Reduce a WebP image to under 500 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 WebP in — the 500 KB target is set and WebP output is selected — and the tool keeps the highest quality that stays under 500 KB.
Only as much as needed to hit the target. It shows a preview so you can check before downloading.
No — compression runs in your browser and the file never leaves your device.
The 500 KB WebP limit is common on large, high-quality web images where WebP keeps the file lean. Set it above and download a WebP that fits.
At 500 KB a WebP is visually lossless for a single photo while staying web-fast.
A WebP at 500 KB often matches a 1 MB JPG at the same quality. You can also use the image compressor for JPG and PNG input.
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.
