Compress Image — frequently asked questions
Does compressing an image lose quality?+
JPEG and WebP compression is lossy, so there is some quality loss — but at 60–80% quality it is usually invisible while the file shrinks a lot. PNG stays lossless.
Can I compress to an exact file size?+
Yes. Enter a target in KB and the tool binary-searches the quality (and downscales if needed) to land at or just under it.
Is my image uploaded?+
No. The image is decoded and re-encoded with a <canvas> in your browser. It never leaves your device.
What formats are supported?+
JPG, PNG, WebP, plus HEIC/HEIF and TIFF as input.
Do you upload my files to a server?+
No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.
Is there a file size limit?+
There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
