JPEG, PNG, WebP, GIF, BMP — up to 25MB
100% private: compression happens entirely in your browser using the canvas API. Your images never leave your device — nothing is uploaded to any server.
Compress an image down to an exact file size target, like 100KB or 500KB. The tool tunes the compression quality first and reduces dimensions only if needed, outputting JPEG or WebP — and it tells you honestly if the target is not achievable for your image.
Frequently asked questions
How do I compress an image to under 100KB?
Upload the image, enter 100KB as the target, and the tool searches for the highest quality that fits under that size, shrinking the dimensions only as a last resort. You then download the result and see the exact final size.
Why can’t my image reach the target size?
Very small targets can be unreachable for large or detailed images without making them unusably small or blurry. If that happens the tool says so rather than silently producing a poor result — try a slightly larger target or accept smaller dimensions.
Should I choose JPEG or WebP?
WebP usually reaches the same visual quality at a smaller size, so it is the better choice where supported. Choose JPEG if you need maximum compatibility with older software or strict upload requirements.
Is my image uploaded during compression?
No. The compression runs entirely in your browser, so photos never leave your device — safe for documents, IDs and personal pictures.
