Get any photo under 150 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 150 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 150 KB target usually comes from forum and CMS uploads, blog images and forms that sit between the common 100 KB and 200 KB caps. Set it above and download a file that lands just under the cap.
At 150 KB a full-size photo keeps good clarity with only slight quality loss. Dimensions are usually preserved.
If the image only displays small on the page, resize it down first — you will get even cleaner results well under 150 KB. 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 150 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 150 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.
