Every time you upload an image, WordPress doesn’t just store your file — it generates a separate cropped copy for every registered image size. A fresh install already creates three (thumbnail, medium, and large) on top of the original, so a single upload becomes four files on your server.
Themes and plugins add many more. A typical site might register hero, slider, product thumbnail, team member, and testimonial sizes — and WooCommerce adds several of its own. With six registered sizes, one upload turns into seven files, even when the page only ever displays one of them. The rest sit on disk doing nothing but consuming space.
Multiply that across hundreds of posts, pages, and products and the waste adds up fast: bloated storage, slower backups, and longer upload processing. It’s especially painful on WooCommerce sites, where uploading a single banner or hero image also generates the full set of product thumbnail sizes you’ll never use for that image.
WP Image Sizes fixes this by letting you decide which sizes WordPress is allowed to create.
<ul>
<li>Per post type control — Assign the exact image sizes that matter to each post type from a simple settings page. A slider post type might only need one large size; testimonials might only need a thumbnail.</li>
<li>Choose sizes at upload time — When you add media, the uploader shows the available sizes so you can pick what gets generated for that specific upload.</li>
<li>Disable thumbnails entirely — Skip generating any additional sizes for a post type or a single upload when you only need the original.</li>
<li>No lock-in — WP Image Sizes never caches or alters your files. Any images already generated stay intact, even if you deactivate or remove the plugin.</li>
</ul>
The result is a leaner media library, less wasted disk space, and a faster, lighter WordPress site.
<h3>PRO</h3>
The free plugin controls which sizes get generated on new uploads. WP Image Sizes Pro extends this to your existing media and adds automation:
<ul>
<li>Bulk Create Image Sizes — Generate selected image sizes for all existing images of a chosen post type. Perfect after registering a new size or switching themes.</li>
<li>Bulk Delete Image Sizes — Remove unwanted image size files from existing media to reclaim server space in one click.</li>
<li>Create Images on Runtime — Automatically generate a missing image size the moment it is first requested on the front end, instead of pre-creating every size.</li>
</ul>

WP Image Sizes

Take control of the image sizes WordPress generates. Pick only the sizes you actually use, per post type, and reclaim wasted server space.

Every time you upload an image, WordPress and your theme create several extra copies — often eight to ten files per image. On shared hosting with inode (file count) limits, this fills your quota fast, slows down backups, and wastes disk space.
ShinPix gives you back control:
<ul>
<li>Choose which image sizes are generated. See every size registered by WordPress and your theme, with dimensions, and disable the ones you do not use.</li>
<li>See your savings. ShinPix shows how many files each upload stores now versus the maximum, so you can see the inodes you save at a glance.</li>
<li>Safe by default. ShinPix flags the sizes the WordPress admin and block editor rely on, and warns you before you disable them.</li>
<li>Cap oversized uploads. Automatically scale down huge phone photos (often 4000px+) to a sensible maximum, keeping web quality while cutting file size.</li>
<li>Convert to WebP. Create a lighter WebP copy of every new upload and serve it automatically to browsers that support it — with the original kept as a fallback. ShinPix detects whether your server can produce WebP and disables the feature gracefully if it cannot.</li>
<li>Compress on upload. Set the quality used for the images WordPress generates, so every size is leaner.</li>
<li>Optimize your existing library. Scan what is already in your Media Library and convert it to WebP in the background, batch by batch, with a progress bar you can pause and resume. Optimize or re-optimize a single image right from the Media Library, and retry anything that failed.</li>
</ul>
ShinPix is built for the real world of budget shared hosting. It is lightweight, adds no front-end overhead, and only changes what happens at upload time.
Coming soon (and on the roadmap):
<ul>
<li>AVIF conversion (Pro)</li>
<li>Scheduled, fully automatic background processing (Pro)</li>
<li>Offload to S3, Cloudflare R2, Wasabi and other object storage to remove image files from your server entirely</li>
</ul>
ShinPix is part of the ShinKit family of WordPress tools.
