I Built a Free Image Compressor That Never Uploads Your Files

#privacy #webdev #opensource #javascript

The Problem

Every time you use an online image compressor, your files get uploaded to someone else computer. TinyPNG does it. Compressor.io does it. Even most so-called free tools collect your data.

Images can contain sensitive stuff -- screenshots, private photos, business documents, unreleased designs. Why should making them smaller require handing them to a stranger?

The Solution: Squash

Squash is a free, open-source image compressor that runs entirely in your browser.

?? No uploads -- everything stays on your device
? Instant compression -- no waiting for network round-trips
?? Multi-format -- JPEG, PNG, WebP support
?? Batch up to 50 images (PRO) or 5 (free)
??? Quality slider -- full control from 1% to 100%
?? Dark mode -- works great at night

How It Works

Squash uses the browser Canvas API to decode images, apply compression settings, and re-encode them at your chosen quality level. All processing happens on your device.

No server. No upload. No privacy concern.
