Reduce a WebP image to under 100 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 100 KB target is set and WebP output is selected — and the tool keeps the highest quality that stays under 100 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 100 KB WebP limit is common on fast-loading web images and thumbnails capped at 100 KB. Set it above and download a WebP that fits.
At 100 KB a WebP looks sharp at full size — and smaller than the equivalent JPG.
Use WebP for sites you control for the best size-to-quality ratio. You can also use the image compressor for JPG and PNG input.
Drop your image into the box above — the 100 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 100 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 100 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.
