About CompressPrivacy
From the official readme · v1.0.0Description
CompressPrivacy Private Image Compression compresses images locally to WebP or AVIF entirely in your browser, using your own CPU — no server-side processing, no external API, no usage limit.
All compression happens on one dedicated screen: Media → Bulk Optimizer. Drop or select any number of images there, adjust the quality slider if you like, and each one is compressed and uploaded straight into the Media Library, with live per-file and total percentage-saved shown as it goes.
Uploading anywhere else in WordPress — the Media Library’s own upload tab, a product image, a featured image, a gallery — is untouched by this plugin by design. The workflow is: compress what you need on the Bulk Optimizer page first, then select the already-compressed file from the Media Library wherever you actually need it.
How it works
- On the Bulk Optimizer page, each selected image is drawn to an in-memory
<canvas>and re-encoded viacanvas.toBlob()to WebP, or AVIF where the browser supports it. - The compressed file is uploaded to a dedicated endpoint that inserts it into the Media Library the standard WordPress way (
wp_handle_upload()+wp_insert_attachment()). - If compression fails, isn’t smaller than the original, or the browser doesn’t support the required APIs, the original file uploads unmodified — nothing is ever blocked.
- Up to a few files compress and upload concurrently, so large batches don’t process one at a time.
Notes
- Animated GIFs are skipped by default (canvas conversion would drop the animation); this is configurable.
- AVIF encoding support varies by browser; the plugin detects support automatically and falls back to WebP.
- Already-optimized formats (WebP, AVIF, SVG) are left untouched.
Installation
- Upload the
compressprivacy-private-image-compressionfolder to/wp-content/plugins/. - Activate the plugin through the ‘Plugins’ menu in WordPress.
- Go to Media → Bulk Optimizer to compress and upload images. Go to Media → Image Optimizer to set defaults (format, quality, max dimensions, batch size).
Frequently asked questions
Does this compress images automatically when I upload them normally?
No. Compression only happens on the Media → Bulk Optimizer page. Compress what you need there, then select the compressed file from the Media Library wherever you actually want to use it.
Does this replace or resize existing images already in my library?
No. It only affects images you run through the Bulk Optimizer page.
Does it need an API key or account?
No. All processing happens locally in the browser using standard Canvas APIs.
What if a browser doesn’t support the Canvas/Blob APIs?
The plugin detects this and uploads the original file unmodified — nothing is blocked.
