Reduce a JPG photo to under 50 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 50 KB target is set — and the tool finds the best JPEG quality that stays under 50 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 50 KB JPG limit is common on passport-style photos on exam and visa forms that ask for a JPG under 50 KB. Set it above and download a JPG that fits.
A cropped JPG headshot fits 50 KB cleanly. The tool keeps the highest JPEG quality that stays under the cap.
Match the required 3.5×4.5 proportions before compressing so quality is not wasted on pixels you will crop away. You can also use the image compressor for PNG and WebP.
Drop your image into the box above — the 50 KB target is already set — and the tool runs a rapid binary search over quality levels, measuring the true output size at each step until it lands on the highest quality that still fits under 50 KB. You get a preview before downloading, so there are no surprises. If the image is very large for a tight target, it also gently reduces the pixel dimensions, because a slightly smaller but clean image always looks better than a full-size one riddled with compression artefacts.
Upload forms reject anything over their stated limit, so "roughly smaller" is not good enough — you need to land under 50 KB on the first attempt. Aiming for the exact size gives you the best-looking image that still passes, instead of over-compressing out of caution and ending up with something needlessly blurry.
