Free Image Compressor: Shrink JPEG, PNG & WebP Without Losing Quality
Tooly · 2026-08-02 · 5 min read
A 5MB phone photo is overkill for nearly everything: email limits, web pages, client portals, and CMS uploads all choke on huge files. A free image compressor fixes that in seconds — and the best ones run entirely in your browser, so your photos never leave your device.
Why compress images?
- Email them — most providers bounce files over ~25MB; compression gets you under instantly
- Speed up your website — every 100KB saved loads faster and ranks better
- Save storage — compressed archives and drives go further
- Upload anywhere — portals and forms reject oversized files
Compress images free with Tooly
The Tooly Image Compressor handles JPEG, PNG, and WebP:
- Drag in your images — compress in your browser, nothing uploaded
- Tune quality to balance size vs. fidelity
- Download the compressed files instantly
- Free forever, no account, no watermark, no size caps
How much can you shrink files?
| File type | Typical reduction |
|---|
| JPEG photo (5MB → ~400KB) | ~90% smaller |
| PNG screenshot (2MB → ~300KB) | ~85% smaller |
| WebP web image | ~50-70% smaller at same quality |
Best practices
- Compress a copy, keep your original — never overwrite the master
- Use WebP for web, PNG for logos and transparency, JPEG for photos
- Compress before uploading to your site builder, not after
- For business: InvoiceForge logos and Image to PNG conversions pair well
