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.

With this plugin, users can add and remove intermediate image sizes. The plugin can also make copies of existing images with these new sizes. You will be able to use the images in your posts or use them in your theme with the ‘Get the image’ plugin or with WordPress 2.9’s <code>the_post_image</code> feature.

Additional image sizes

Allows you to create additional image sizes (in addition to the thumbnail, medium and large size that are default) for your blog.
