Compress PDF — frequently asked questions
How does the compression work?
Each page is redrawn as an optimised image at the level you choose. This shrinks scans and photos a lot. Text becomes part of the image, so for text-only PDFs keep the original if you need to select text.
How do I compress a PDF to under 200 KB?
Choose Strong compression. If it is still too large, split the PDF first or remove pages you do not need.
Is it really free?
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.
