Image Compressor — frequently asked questions
Will compression reduce quality?
At 70–85% quality, the difference is usually invisible while the file is much smaller.

Yes. Qu-Outil is completely free with no sign-up, no watermark and no usage limits.
Are my files uploaded?
No. The work is done in your browser on your own device, so your files are never uploaded or stored anywhere.
