Compress to 1 MB

Add an image to enable compression.

Compress an image to 1MB free and privately in your browser. A 1MB cap is common on forums, support ticket systems, web portals and email providers — and while it sounds roomy, photos straight off a phone or camera are routinely 3–10MB and get rejected.

This tool brings any JPG, PNG or WebP under 1MB automatically, choosing the highest JPEG quality that fits. At this budget virtually every photo keeps its original dimensions and looks exactly like the source — the savings come almost entirely from smarter encoding. Nothing is uploaded: the compression runs on your device, free, with no sign-up.

Frequently asked questions

Will I notice any quality loss at 1MB?

No — 1MB is a large budget for a single image. Photos keep their full dimensions and compress at high JPEG quality, so the result is visually identical to the original for on-screen use and most printing.

My PNG screenshot is 4MB — will this work?

Yes. Large PNGs compress especially well because the tool re-encodes them as high-quality JPEG, which stores photographic and screenshot content far more efficiently. A 4MB PNG typically lands well under 1MB. Note the output is JPG, so PNG transparency is filled with white.

Is the compression private?

Yes. It runs entirely in your browser with the Canvas API — your image is never uploaded to a server. The tool is free with no account needed.
