JPG / PNG / WebP — Stays on your device — nothing is uploaded.

How it works

Drop a JPG, PNG, or WebP image, adjust the quality if you like, then compress. The image is re-encoded entirely in your browser — nothing is uploaded.

Frequently asked questions

Does this tool upload my image anywhere?
No. Your image is decoded and re-encoded entirely in your browser using the Canvas API. It never leaves your device.
Is there a file size limit?
No hard limit from us — the tool runs in your browser, so very large images are limited by your device’s memory rather than a server quota.
Why didn’t my PNG get much smaller?
PNG is a lossless format — there’s no quality slider to trade off, so savings depend on how the original file was encoded rather than how much you compress it here.
