Get any photo under 500 KB at the best possible quality — 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 it in — the 500 KB target is already set — and the tool binary-searches the highest quality that still fits, then hands you the file. No slider guesswork.
No. Compression runs entirely in your browser; the image never leaves your device.
JPG, PNG and WebP input. Output is JPG (works everywhere) or WebP (smaller).
The 500 KB target usually comes from high-quality web images, portfolio shots and any upload capped at half a megabyte. Set it above and download a file that lands just under the cap.
At 500 KB compression is effectively invisible for a single photo. Use it when quality matters more than tiny size.
For a website you control, exporting to WebP fits even more quality into 500 KB — convert after compressing. For other targets, use the image compressor hub.
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 500 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 500 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.
Every limit below uses the same tool with a different target, so you can go straight to the one your form or inbox actually asks for. If you only need a smaller file size in general and no exact number, pick the next limit up from where you are now and keep more quality.
Not sure which limit you need, or want to type an exact number of your own? The image compressor takes any target you give it.
