It uses Imagick (preferred) or GD (fallback) — no external dependencies or API keys needed. **Features:** * Automatic optimization on every upload * Bulk optimization of the existing media library * Optional WebP conversion for every image * Optional automatic .webp serving via .htaccess under the same original URL (no redirects) * WordPress thumbnail optimization * Automatic backup of the original file before processing * Optional thumbnail backups (disabled by default) plus a Maintenance screen to scan, download and purge accumulated backups * Detailed savings statistics per file type * Copyright/authorship EXIF metadata preserved after stripping * Optional automatic resizing with configurable maximum width and height * Compatible with Imagick (preferred) and GD (fallback) * No external dependencies — works on any shared hosting ### Requirements * WordPress 5.8 or higher * PHP 7.4 or higher * Imagick or GD extension enabled on the server ## Screenshots [⌊Settings — image resizing, compression quality (JPEG/PNG/WebP) and processing options⌉⌊Settings — image resizing, compression quality (JPEG/PNG/WebP) and processing options⌉[ Settings — image resizing, compression quality (JPEG/PNG/WebP) and processing options [⌊Bulk Optimization — reoptimize your entire existing media library with a progress bar⌉⌊Bulk Optimization — reoptimize your entire existing media library with a progress bar⌉[ Bulk Optimization — reoptimize your entire existing media library with a progress bar [⌊Savings Statistics — totals by file type and a log of the most recent optimizations⌉⌊ Savings Statistics — totals by file type and a log of the most recent optimizations⌉[ Savings Statistics — totals by file type and a log of the most recent optimizations [⌊Diagnostics — Imagick/GD availability, WebP support and uploads folder permissions⌉⌊ Diagnostics — Imagick/GD availability, WebP support and uploads folder permissions⌉[ Diagnostics — Imagick/GD availability, WebP support and uploads folder permissions [⌊Settings — backup options and the new automatic WebP serving via .htaccess (no redirects)⌉⌊Settings — backup options and the new automatic WebP serving via .htaccess( no redirects)⌉[ Settings — backup options and the new automatic WebP serving via `.htaccess` (no redirects) [⌊Maintenance — scan, download and purge accumulated .niquelao-bak backup files in batches⌉⌊Maintenance — scan, download and purge accumulated .niquelao-bak backup files in batches⌉[ Maintenance — scan, download and purge accumulated `.niquelao-bak` backup files in batches ## Installation 1. Upload the `niquelao-image-optimizer/` folder to `/wp-content/plugins/` 2. Activate the plugin from **Plugins Installed Plugins** 3. Configure it under **Niquelao Optimizer Settings** ## FAQ ### Does it work on shared hosting? Yes. It uses the PHP Imagick or GD libraries, available on virtually all shared hosting providers. ### Are the original images saved? Optionally. Enable “Save backup” in the settings to keep a `.niquelao-bak` copy alongside each processed file. ### My hosting has limited disk space / inodes, how do I clean up backups? By default only the full-size original is backed up, not every thumbnail size. Go to **Niquelao Optimizer Maintenance** to scan for accumulated `.niquelao-bak` files, download a ZIP copy, and purge them in batches. ### Is copyright information preserved? Yes. The EXIF/IPTC Copyright, Artist and Author fields are preserved after stripping the rest of the metadata. ## Reviews ![](https://secure.gravatar.com/avatar/0c247cdef5cf26b990356c513524cba5a4d550bef468c028676190079fcbf555? s=60&d=retro&r=g) ### 󠀁[De lo mejor en optimización de imagen](https://wordpress.org/support/topic/de-lo-mejor-en-optimizacion-de-imagen/)󠁿 [Carlos](https://profiles.wordpress.org/cvaneyk/) October 2, 2026 Te optimiza todas las imágenes de la galería, mantiene la calidad y no altera nada en el frontend, incluso te hace una copia si quieres.

No functional change. #### 1.5.1 * Fixed: Plugin Check findings — replaced direct `unlink()` calls with `wp_delete_file()` in the Maintenance ZIP download and cleanup routines * Fixed: added justified `phpcs:ignore` annotations for the unavoidable direct ` is_writable()`/`readfile()` filesystem calls used to manage `.htaccess` and stream the temporary backup ZIP (no WP_Filesystem equivalent exists for these specific operations) * Fixed: added justified `phpcs:ignore` annotations for `$_POST['offset']`/`$_POST[' token']` reads in Maintenance AJAX handlers, where the nonce is already verified via `check_ajax_referer()` inside `check_permissions()` earlier in the same method * Fixed: removed the remote Google Fonts `@import` in the admin stylesheet (present since the first approved version) — admin UI now uses a local system-font stack, with no third-party assets loaded * Fixed: missing i18n wrapper on the “No Imagick/GD detected” troubleshooting copy in the Diagnostics page * Fixed: hardcoded Spanish strings in the Media Library inline JS (single-image optimize button) now routed through PHP `__()` and passed to the script as a translatable object * Changed: README.md rewritten to match the current version and defer to readme. txt as the single source of truth for the changelog, instead of duplicating ( and drifting out of sync with) it #### 1.5.0 * Added: optional setting “Servir WebP automáticamente” — inserts/removes a `.htaccess` block (via WordPress’ insert_with_markers()/extract_from_markers()) that serves the `.webp` version under the same original URL when the browser supports it, with no redirects and no URL changes * Added: status indicators for mod_rewrite availability, `.htaccess` writability and whether the rule block is actually installed * Added: the `.htaccess` block is automatically removed on plugin deactivation and uninstall, leaving no leftover server rules #### 1.4.0 * Added: optional “Keep thumbnail backups” setting (off by default) — when disabled, only the full-size original gets a `.niquelao-bak` copy instead of every generated thumbnail size, saving disk space and inodes * Added: new Maintenance screen to scan, download (as ZIP) and bulk-purge accumulated`. niquelao-bak` files, processed in batches via AJAX to support shared hosting with execution time/inode limits * Added: uninstall routine now also removes the temporary ZIP folder and the new backup-thumbs option #### 1.3.5 * Fixed: settings page hook suffixes were calculated manually and didn’t match the real hook suffixes generated by WordPress (which derive from the top-level menu_title, not the menu slug), causing CSS/JS to fail to load on Bulk Optimization, Statistics and Diagnostics pages * Fixed: admin styles/scripts now use the real hook_suffix returned by add_menu_page()/ add_submenu_page() instead of a hardcoded guess * Fixed: media library “Optimize” button (upload.php/post.php) registered its own style/script handle instead of relying on a handle that wasn’t enqueued on those screens * Fixed: synced plugin version number across the main file header, the NIQUELAO_VERSION constant and readme.txt Stable tag * Fixed: missing i18n wrapper on one bulk-optimization status string #### 1.3.2 * Unified license to GPL-2.0-or-later across all files * Added full internationalization (i18n) via **() and esc_html**() functions * Updated Text Domain header to match plugin slug (niquelao-image-optimizer) * Removed deprecated load_plugin_textdomain() call (auto-loaded since WP 4.6) * Created uninstall.php to clean up table, options and postmeta on uninstall * Fixed require_once order: all includes at the top of the main file * languages/ folder ready for translations #### 1.3.1 * Updated Plugin URI to kokeperez.es #### 1.3.0 * Added automatic resizing with configurable maximum width and height * EXIF Copyright/Artist metadata now preserved after stripping (Imagick and GD) #### 1.2.0 * Atomic file writes using a temporary file * Improved diagnostics page #### 1.1.0 * Bulk optimization with progress bar * WebP conversion support * Statistics page #### 1.0.0 * Initial release ##
