Good to know: Strong compression turns each page into an image, so text can no longer be selected or searched. Light compression keeps text but saves less space. If the result would be larger than the original, we keep your original.

Questions
How much smaller will it get?
Scanned and photo-heavy PDFs often shrink by 50–90% with Strong. Text-only PDFs are usually small already.
Is it really free?
Yes. Five tasks a day are free with no watermark and no account. Paid plans with unlimited use are coming.
Where do my files go?
Nowhere. Vellafolio processes files inside your browser. They are not uploaded, stored or seen by anyone.
