Image compression that runs in your browser: works on any hosting, better quality, no external servers, and compresses before upload.

Squeeze uses browser-side codecs (the same family as Squoosh.app)—not Imagick on your server and not a remote API. That means it works on weak shared hosting, your images never leave for third-party optimization servers (privacy- and GDPR-friendly), and files can be squeezed before they hit the Media Library. Convert to WebP, bulk-optimize existing images, and tune per-format quality—with no API keys and no monthly quotas.

Why Squeeze:

🖥️ Works on any hosting — compression runs in the browser, so you do not need Imagick, binaries, or a powerful server.
🔒 No external servers — image bytes stay on your site; nothing is uploaded to a cloud optimizer.
⬆️ Compress before upload — shrink images in Gutenberg, GenerateBlocks, Instant Images imports, and the Voxel theme before (or right after) files hit the Media Library (Elementor on-upload squeeze is available in Premium).
📝 Form uploads — compress visitor photos in Contact Form 7 file fields before submit (Gravity Forms single- and multi-file fields in Premium).
⚡ Direct WebP conversion — convert JPG/PNG to WebP and replace the original file on disk (no duplicate copies cluttering storage).
♾️ No compression quotas — squeeze your entire Media Library; the plugin does not impose a monthly image cap.
🛡️ Safer huge uploads — soft megapixel limits reduce browser OOM; very large uploads skip after-upload thumbnail re-squeeze and stay marked as client-compressed.

The result: smaller files, faster page loads, and lower hosting storage—without SaaS fees or API keys.

🌟 New in 1.8.3

Optional anonymous usage telemetry (off by default): opt in under Settings Squeeze to share feature events such as a settings_saved snapshot on Save, bulk/single squeeze, and upgrade clicks — never image bytes or filenames. See the Privacy section.

Also in 1.8

Squeeze form uploads: compress images in the visitor’s browser on front-end forms — Contact Form 7 (free) and Gravity Forms single- / multi-file fields (Premium).
Safer huge uploads: soft megapixel limits, skip after-upload thumbnail re-squeeze on oversized files, optional full-size WebP sidecar, and clearer client-compressed markers so precompressed uploads are recognized on attach.
Bulk savings: site total on Media Squeeze Bulk Tools (tracked since 1.8.0) and a completion summary after each run.

How does Squeeze work?

Open the Media Library, run Bulk Squeeze, or upload a new image — Squeeze runs Google Chrome team–backed codecs (the same family as Squoosh.app) inside your browser via Web Workers. No account, no API key, no off-site upload queue.

Privacy

Image compression runs in your browser; Squeeze does not upload your images to a third-party optimizer.

Optional anonymous usage telemetry is off by default. If you opt in (Settings Squeeze, or the one-time notice on Squeeze admin screens only), Squeeze may send named feature events—for example settings_saved (a snapshot of options such as WebP mode, form uploads, backup, and selected formats when you save), bulk/single squeeze start or finish, upload squeeze, and upgrade UI clicks. Events go to a first-party endpoint (telemetry.pluginarium.com) and are processed with PostHog EU Cloud. They include plugin version, free/premium edition, and an anonymized site id—not image bytes, filenames, attachment IDs, or media URLs. Individual setting toggles are not sent until you save. Opting out never blocks features; you can change your choice anytime under Settings Squeeze.
