It compresses images automatically on upload, batch-converts your entire media library to WebP and AVIF, configures Apache to serve next-gen formats automatically, and scans your site for common technical SEO issues. #### Features **Auto-Compress on Upload** Every JPG/PNG above a configurable size threshold is automatically scaled and compressed before WordPress generates its thumbnail sizes. No extra steps needed. **Bulk Compression** Run a background batch job to compress all existing images in your media library. Progress is tracked and the job runs asynchronously — it won’t block your browser. **WebP Converter** Batch-convert all JPG/PNG/GIF files in your uploads directory to WebP format. Runs in the background using WP-Cron or a loopback HTTP request. Supports both Imagick and GD libraries. **AVIF Converter** Convert images to AVIF — the next-generation format that can be 30–50% smaller than WebP. Requires Imagick 7+ with AVIF support or PHP 8.1+ with GD `imageavif()`. The plugin detects support automatically and warns you if AVIF is unavailable on your server. **Apache .htaccess Configuration** One click adds `mod_rewrite` rules to your `. htaccess` so Apache automatically serves `.webp` files to browsers that support them, with no code changes required in your theme. **Image Dimensions Scanner** Detects images ≥ 1600 px wide that are used in posts or as featured images. Helps you find oversized images that slow down page loads, along with their file sizes, dimensions, and WebP/AVIF conversion status. **Site Audit** Scans your site for the most common technical issues: missing alt text, oversized images, missing SSL, outdated plugins, pages without Open Graph tags, and more. Results include actionable recommendations. **Dashboard Widget** A compact stats panel on the WordPress admin dashboard showing compression savings, WebP/AVIF conversion counts, and a link to the optimizer. #### Requirements * PHP 8.0+, WordPress 6.0+ * GD or Imagick PHP extension (for WebP/compression) * Imagick 7+ with AVIF or PHP 8.1+ GD (for AVIF conversion) * Apache + `mod_rewrite` (for automatic WebP serving via `.htaccess`) #### Privacy This plugin does not collect any personal data and does not make any external HTTP requests. ## Ảnh màn hình * [[ * Main dashboard — image health score, library stats, and optimization overview. * [[ * WebP Converter tab — batch conversion controls, server library status, and progress tracking. * [[ * Site Audit tab — one-click free scan for performance, SEO, and security issues. ## Cài đặt 1. Upload the `mits-image-optimizer` folder to `/wp-content/plugins/`. 2. Activate the plugin via **Plugins Installed Plugins**. 3. Navigate to **MITS Optimizer** in the WordPress admin sidebar. 4. (Optional) Click **Konfiguruj .htaccess** on the WebP tab to enable automatic browser- side WebP delivery. ## Hỏi đáp ### Does this plugin delete my original images? No. Original images are never deleted. WebP and AVIF files are saved alongside originals with a `.webp` or `.avif` extension (e.g. `photo.jpg` `photo.jpg.webp`). ### What happens if my server doesn’t support AVIF? The AVIF tab will display a warning with the reason (e.g. Imagick version too old, or GD `imageavif()` not available). WebP conversion and compression still work independently of AVIF support. ### Does it work with object-cache or page-cache plugins? Yes. The plugin only modifies image files in your uploads directory and your `.htaccess`. It is compatible with all major caching plugins. ### Can I run compression and WebP/AVIF conversion at the same time? It is not recommended. Run one batch job at a time to avoid server load spikes and to keep progress tracking accurate. ### Is the .htaccess change reversible? Yes. The plugin wraps its rules in clearly marked comment blocks (`# BEGIN MITS WebP` … `# END MITS WebP`). You can remove them manually or via the plugin button. ### What image formats are supported? Auto-compression and bulk compression support JPG, JPEG, PNG, and GIF. WebP and AVIF conversion support the same formats. GIF files are converted to static WebP/ AVIF (animation is not preserved). ## Đánh giá ![](https://secure.gravatar.com/avatar/47d3fbbacac6c1bb5a24cbbedd50749371a5d69fcd16ad90702bd2dc0d0289cd? s=60&d=retro&r=g) ### 󠀁[Does exactly what it promises](https://wordpress.org/support/topic/does-exactly-what-it-promises-38/)󠁿 [programistawp](https://profiles.wordpress.org/programistawp/) 28 Tháng 5, 2026 Does exactly what it promises. Auto-compression on upload works out of the box, WebP batch conversion runs smoothly in the background without blocking the browser, and the .htaccess configuration for automatic WebP serving is a one-click setup. The Image Dimensions Scanner is a nice bonus for catching oversized images before they become a performance problem.

[Duyệt code](https://plugins.trac.wordpress.org/browser/mits-image-optimizer/), check out [SVN repository](https://plugins.svn.wordpress.org/mits-image-optimizer/), hoặc theo dõi [nhật ký phát triển](https://plugins.trac.wordpress.org/log/mits-image-optimizer/) qua [RSS](https://plugins.trac.wordpress.org/log/mits-image-optimizer/?limit=100&mode=stop_on_copy&format=rss). ## Nhật ký thay đổi #### 1.2.12 * Fix: ajax_import_settings now checks actual .htaccess file state (htaccess_is_active) instead of DB value when deciding whether to remove rules — previously if DB already said false but file still had rules, removal was skipped. * Improve: conflict banner on settings page now has a one-click “⚡ Zastosuj zalecane ustawienia” button — no need to scroll to the import section. * Improve: after applying settings, conflicts list updates inline without page reload — form fields, top banner and inline list all update in place. * Improve: “Wygeneruj i zastosuj” can be triggered directly from the conflict banner button (generates recommended + applies in one click). #### 1.2.11 * Fix: mits_import_settings and mits_recommended_settings were missing from the AJAX registration array — WordPress returned 0 for both actions causing “Błąd.”/“ Błąd zapisu.” errors. #### 1.2.10 * Add: Competing plugin detection in conflict checker — warns when WebP Converter for Media, ShortPixel, Smush, Imagify, EWWW, Optimole, TinyPNG or other optimization plugins are active alongside MITS. * Add: WP Super Cache + PHP WebP Serving conflict detection — warns about cache serving wrong format to non-WebP browsers. * Add: Autoptimize + PHP WebP Serving conflict hint. * Add: Import settings — new card on settings page with “Wygeneruj zalecane” button( picks optimal config for detected server: .htaccess for Apache/LiteSpeed, PHP WebP Serving for Nginx) and “Zastosuj” to apply JSON. * Add: mits_recommended_settings and mits_import_settings AJAX endpoints. * Add: After import, post-apply conflicts are shown inline without full page reload; page refreshes after 1.4s. #### 1.2.9 * Add: Server detection (Apache / LiteSpeed / Nginx) — settings page now shows “ Twój serwer” badge on the relevant section, disables .htaccess controls on Nginx with an explanatory banner, and highlights the Nginx config block. * Add: Settings conflict detection — plugin detects and displays warnings for conflicting configurations (e.g. .htaccess enabled on Nginx, double WebP serving, setting enabled but no .webp files exist). * Add: Conflicts section in settings page — shown as an orange banner above settings cards whenever conflicts are detected. * Add: Extended JSON debug export — now includes server info, Imagick format capabilities( WebP/AVIF read/write), disk free space, active plugins list, memory usage, PHP SAPI, WP_DEBUG state, locale, timezone, and conflict list. * Improve: Dashboard suggestions and score now server-aware — on Nginx, suggestions point to PHP WebP Serving / srcset instead of .htaccess; php_webp_serving counts toward webp_served score. * Improve: Audit no longer flags missing .htaccess on Nginx when PHP WebP Serving or srcset is active. * Improve: server type passed to JavaScript via mitsOptData.server for future JS- side hints. #### 1.2.8 * Fix: .htaccess toggle button now keeps the database setting in sync with the actual .htaccess file state — previously toggling via the UI button could leave htaccess_webp option out of sync with reality. #### 1.2.7 * Add: JSON export / debug button on Settings page — downloads a full status snapshot: plugin version, system info (PHP, GD, Imagick, memory), all settings, compression/ WebP/AVIF/lossless stats, and last dashboard scan results. * Fix: Settings and About pages now inherit the full-width dark background layout matching the main optimizer page. #### 1.2.6 * Fix: Settings page (?page=mits-settings) now renders a clean standalone view — plugin header + settings panels only, no tab navigation. Settings is only accessible from the WordPress sidebar menu. * Remove: Settings tab and panel removed from the main tabbed interface. #### 1.2.5 * Fix: visiting ?page=mits-settings or ?page=mits-about now redirects to the main plugin page with the correct tab pre-selected, instead of rendering the full interface again from scratch. #### 1.2.4 * Fix: “Ustawienia” tab added to the main navigation bar — visiting ?page=mits- settings now correctly opens the settings panel instead of showing the dashboard.. htaccess and compression controls are now always reachable via the tab. #### 1.2.3 * Fix: dashboard suggestion buttons for “.htaccess” and “Settings” now navigate correctly to the Settings submenu page instead of silently failing (the settings panel is a separate WP admin page, not a tab). #### 1.2.2 * Fix: JPEG WebP scanner now finds ALL JPEG attachments, including those that already have a .webp sidecar (created by bulk WebP Converter). Previously these were skipped, showing “no files found” on sites where WebP Converter had already run. * Improvement: JPEG WebP conversion reuses an existing .webp sidecar file instead of re-encoding, then removes the original JPEG and updates WordPress metadata. Column in results table shows current WebP size alongside JPEG size. #### 1.2.1 * Fix: .htaccess block now includes AVIF serving rules before WebP — browsers receive. avif when the file exists, falling back to .webp then original. Existing installations with .htaccess active are updated automatically on next save. * Fix: PHP WebP Serving now also activates for browsers that send image/avif in the Accept header; AVIF is preferred over WebP when both exist. * Fix: WebP/AVIF srcset filters (WebP in srcset + PHP Serving) now prefer AVIF over WebP when the browser accepts it. * Fix: image scanner (bulk compress, WebP/AVIF scan) no longer skips files in directories with unreadable subdirectories; uses CATCH_GET_CHILD to continue past permission errors instead of aborting silently. * Fix: removed false-negative check in scan_images that could exclude .jpg files in edge-case directory structures. * Improvement: Nginx configuration snippet updated — dual map variables for AVIF and WebP with try_files fallback chain. #### 1.2.0 * Add: JPEG WebP converter in the PNG JPG tab — scans all JPEG attachments without a .webp counterpart, converts each one and replaces the original, updates WordPress metadata, thumbnails, and all content URLs. * Change: PNG scan now finds all PNG files regardless of size (previously filtered to ≥ 150 KB). #### 1.1.0 * Add: PNG backup restore — lists saved backup ZIPs, one-click restore extracts original PNGs, reverts WordPress metadata, content URLs, and removes .webp files. * Fix: PNG WebP table no longer clips the action button — removed conflicting overflow:hidden from card. * Fix: Admin notices from other plugins (AccessiYes, Rank Math, etc.) are now suppressed on all MITS pages. #### 1.0.9 * Fix: PNG WebP conversion now handles the case where a .webp file already exists( created by WebP Converter) — instead of blocking with “file exists”, it skips re-encoding and proceeds to delete the PNG source and update WordPress metadata. #### 1.0.8 * Add: PHP WebP Serving — replaces image URLs in HTML output with .webp versions when the browser supports WebP and the .webp file exists. Works on Apache and Nginx without any server configuration. Sends Vary: Accept header for correct caching behaviour. Off by default. #### 1.0.7 * Add: “Pobierz ZIP (backup)” button on PNG JPG/WebP tab — creates a ZIP archive of all found PNG originals for safe local backup before conversion. * Change: “Konwertuj wszystkie” now automatically creates a backup ZIP before starting batch conversion; conversion is blocked if backup fails. #### 1.0.6 * Add: “Konwertuj wszystkie” bulk button on the PNG JPG/WebP tab — converts all found PNG files in one click without losing the per-file option. #### 1.0.5 * Add: Nginx WebP serving configuration snippet in Settings (alongside Apache . htaccess). * Change: .htaccess and Nginx sections moved into the Settings page; removed separate. htaccess tab. * Change: Settings and O MITS moved to WordPress sidebar submenu for easier access. #### 1.0.4 * Add: Welcome notice shown after plugin activation with 3-step quick-start guide and a dismiss button. #### 1.0.3 * Fix: Dashboard scan no longer scans the filesystem — uses WordPress database queries instead, making it instant even on stores with 100k+ products. * Fix: WebP/AVIF coverage is now estimated from a 500-attachment sample (extrapolated to full library) rather than iterating all files. #### 1.0.2 * Add: “Settings” quick-link on the Plugins list page. * Fix: Missing logo-mits.svg causing 404 in the admin header. #### 1.0.1 * Fix: AJAX handlers now return proper JSON error responses instead of HTTP 500 HTML on unexpected PHP errors. * Add: Built-in error logger — errors are saved to a log file in the uploads directory for easier debugging. * Add: Hidden diagnostic page at wp-admin/admin.php?page=mits-debug showing system info (PHP, GD, Imagick, upload directory permissions, WP-Cron status) and the error log with a clear button. #### 1.0.0 * Initial release. * Auto-compression on upload with configurable quality and max-width. * Bulk compression with background batch processing and progress tracking. * WebP Converter with Imagick and GD support. * AVIF Converter with Imagick 7+ and GD imageavif() support. * Apache .htaccess automatic WebP serving configuration. * Image Dimensions Scanner detecting oversized images in use. * Site Audit with checks for missing alt, SSL, Open Graph, plugin updates, and more. * WordPress Dashboard Widget with optimization statistics. ## Meta * Phiên bản **1.2.12** * Cập nhật lần cuối **7 giờ trước** * Số lượt cài đặt **Ít hơn 10** * Phiên bản WordPress ** 6.0 hoặc cao hơn ** * Đã kiểm tra lên đến **7.0** * Phiên bản PHP ** 8.0 hoặc cao hơn ** * Ngôn ngữ * [English (US)](https://wordpress.org/plugins/mits-image-optimizer/) * Thẻ * [AVIF](https://vi.wordpress.org/plugins/tags/avif/)[compress](https://vi.wordpress.org/plugins/tags/compress/) [image](https://vi.wordpress.org/plugins/tags/image/)[image optimization](https://vi.wordpress.org/plugins/tags/image-optimization/) [webp](https://vi.wordpress.org/plugins/tags/webp/) * [Nâng cao](https://vi.wordpress.org/plugins/mits-image-optimizer/advanced/) ## Đánh giá 5 trên 5 sao. * [ 1 5-star review ](https://wordpress.org/support/plugin/mits-image-optimizer/reviews/?filter=5) * [ 0 4-star reviews ](https://wordpress.org/support/plugin/mits-image-optimizer/reviews/?filter=4) * [ 0 3-star reviews ](https://wordpress.org/support/plugin/mits-image-optimizer/reviews/?filter=3) * [ 0 2-star reviews ](https://wordpress.org/support/plugin/mits-image-optimizer/reviews/?filter=2) * [ 0 1-star reviews ](https://wordpress.org/support/plugin/mits-image-optimizer/reviews/?filter=1) [Your review](https://wordpress.org/support/plugin/mits-image-optimizer/reviews/#new-post) [Xem tất cả đánh giá](https://wordpress.org/support/plugin/mits-image-optimizer/reviews/) ## Những người đóng góp * [ wpaluchmits ](https://profiles.wordpress.org/wpaluchmits/) ## Hỗ trợ Có điều gì muốn nói? cần giúp đỡ?
