Squishify flips the order. Drag a batch of images into the Squishify editor (right inside wp-admin), resize, tune format and quality with a live before/after comparison, and nothing touches your site until you click Upload. Only the finished, optimized files reach your Media Library. * Real encoders — libavif (AVIF), libwebp (WebP), MozJPEG, and Oxipng (PNG), running as WebAssembly in your browser * Batch queue with per-image format, quality, and effort controls * Resize images individually or all at once to the exact size needed * Batch rename three ways — one image, a numbered sequence, or a name per image * Number a sequence with or without a prefix (gallery-01… or just 1, 2, 3), zero- padded so it sorts correctly * Live before/after comparison loupe * Upload straight to the Media Library when you’re ready * No cloud API, no credits, no quotas — the work happens on your machine * Your images stay private until you upload them to your own site Images are capped at 2560px on the longest edge before encoding — the same threshold WordPress core itself uses (`big_image_size_threshold`). Because the file you upload is already at or under that size, WordPress never generates its own separate `-scaled` copy: what you see in the editor is what ends up in your Media Library, one file, no server-side duplicate. ### Credits Squishify’s WebAssembly encoders are provided via [jSquash](https://github.com/jamsinclair/jSquash)( MIT/Apache-2.0), which wraps libavif (BSD-2-Clause), libwebp (BSD-3-Clause), MozJPEG( BSD-style), and Oxipng (MIT) — all GPL-compatible. The `.wasm` files are unmodified upstream builds. ## Screenshot [⌊The Squishify button, right next to Add New Media File on the Media Library screen.⌉⌊ The Squishify button, right next to Add New Media File on the Media Library screen .⌉[ The Squishify button, right next to Add New Media File on the Media Library screen.

Upload the `squishify` folder to `/wp-content/plugins/`, or install the zip via Plugins Add New Upload Plugin. 2. Activate the plugin. 3. Open Media Squishify, or click the Squishify button on the Media Library screen. ## FAQ ### Are my images sent anywhere for processing? No. All compression, conversion, and resizing happens locally in your browser. The only network transfer is the final upload of finished files to your own WordPress site. ### What formats can it produce? AVIF, WebP, JPEG (MozJPEG), and optimized PNG (Oxipng). AVIF uploads require WordPress 6.5+. ### Uploads fail with an error mentioning a security plugin or firewall Some security hardening (Sucuri, ModSecurity, host firewalls) can block media uploads through the WordPress REST API before WordPress ever sees them. If uploads fail with that message, review your security plugin’s hardening options or ask your host to allowlist REST media uploads (`/wp-json/wp/v2/media`). Squishify uses the same standard upload format as WordPress’s own uploader. ### Does it work with multisite? Yes. Squishify checks the standard `upload_files` capability on whichever site you’re on, so it works whether the plugin is network-activated or activated per-site — no separate configuration either way. ### What happens to my original files? Nothing — Squishify never touches them. Everything happens in your browser on a copy of the image; your source file is only read, never modified. Only the optimized output you choose to upload leaves the editor, and only after you click Upload. ### Why is the first AVIF encode slower than the rest? The AVIF encoder is a WebAssembly module that has to be downloaded and compiled by your browser the first time it’s used in a session. After that one-time warmup, your browser caches the compiled module and subsequent encodes are much faster. ### What browsers are supported? Any current version of Chrome, Firefox, Safari, or Edge. All processing uses standard Web APIs (WebAssembly, Web Workers) with no browser-specific requirements. ## Recensioni Non ci sono recensioni per questo plugin. ## Contributi e sviluppo “Squishify” è un software open source.

[Esplora il codice](https://plugins.trac.wordpress.org/browser/squishify/) segui il [repository SVN](https://plugins.svn.wordpress.org/squishify/), segui il [log delle modifiche](https://plugins.trac.wordpress.org/log/squishify/) tramite [RSS](https://plugins.trac.wordpress.org/log/squishify/?limit=100&mode=stop_on_copy&format=rss). ## Changelog #### 1.3.0 * Rename now has three modes — rename this image, number a whole sequence, or type a name for every image in one pass. * Sequences can skip the prefix entirely, so you can number files 1, 2, 3. * Sequences are zero-padded automatically, so 12 images sort correctly instead of running 1, 10, 11, 12, 2. * Add more images to a numbered batch and they pick up the sequence instead of arriving unnamed. * Switching between rename modes keeps what you already typed. * Fixed an error that could interrupt the first image of a batch with an “Encode failed” message when it was added. * Various interface adjustments. #### 1.2.2 * Adding a batch now eases in: a brief loading pass, then your images arrive in the queue one after another — so you can see at a glance how many landed. * The file heading now shows where you are in the queue (“1 of 15”), next to the filename and dimensions. * “Apply to all” is now a checkbox on the main button instead of a second button competing with it — tick it and Next file becomes Finalize, which processes everything and takes you straight to the summary. * Slimmer format and quality bar, leaving noticeably more room for the image you’re actually working on. * Images scaled down to the maximum working size are now reported once, with a count of how many were affected, instead of a separate notice per image. * Notices and toasts no longer sit on top of dialogs. #### 1.2.0 * Batch rename is now part of the free tier — give a whole set a base name and automatic numbering, no licence needed. #### 1.1.2 * Fixed resized images looking softer or jagged compared to a desktop editor’s export, especially on small or heavily cropped outputs — resizing now uses a sharper algorithm, with safeguards to keep large source photos fast. #### 1.1.0 * Drag a whole folder of images onto the dropzone to queue everything inside it at once. * SVG images now rasterize at a proper working size instead of their (often tiny) declared dimensions. * Added an in-app “what’s new” modal so you’ll see a quick summary the next time a new version ships. #### 1.0.1 * Fix: guard against a file being added to the queue twice from a single drop/select action. #### 1.0.0 * First public release: editor overlay, batch queue, upload to Media Library. #### 0.1.0 * First development release: editor overlay, batch queue, upload to Media Library. ## Meta * Versione **1.3.0** * Ultimo aggiornamento **2 giorni fa** * Installazioni attive **Meno di 10** * Versione WordPress ** 6.5 o superiore ** * Testato fino alla versione **7.0.4** * Versione PHP ** 7.4 o superiore ** * Lingua * [English (US)](https://wordpress.org/plugins/squishify/) * Tag * [AVIF](https://it.wordpress.org/plugins/tags/avif/)[image optimization](https://it.wordpress.org/plugins/tags/image-optimization/) [media library](https://it.wordpress.org/plugins/tags/media-library/)[resize images](https://it.wordpress.org/plugins/tags/resize-images/) [webp](https://it.wordpress.org/plugins/tags/webp/) * [Visualizzazione avanzata](https://it.wordpress.org/plugins/squishify/advanced/) ## Valutazioni Non sono state ancora inviate recensioni.
