Reduce a JPG photo to under 20 KB with the best quality that fits — no upload, no watermark.
JPG, PNG, or WebP — up to 40 MB
🔒 100% private — files are processed in your browser and never uploaded to any server.
Drop your JPG in — the 20 KB target is set — and the tool finds the best JPEG quality that stays under 20 KB. The output stays a JPG.
Only as much as needed to hit the target. It keeps the highest quality that fits and shows a preview before you download.
No — compression runs in your browser and the file never leaves your device.
The 20 KB JPG limit is common on signature uploads and very small photo fields that cap a JPG at 20 KB. Set it above and download a JPG that fits.
A tightly cropped JPG headshot or a signature fits 20 KB while staying legible.
A plain background compresses far smaller than a busy one — crop out the clutter first. You can also use the image compressor for PNG and WebP.
