Questions & answers
How much smaller will my PDF get?
Scanned and photo-heavy PDFs often shrink by 50–90%. Text-only PDFs are usually small already.
Will the text still be selectable?
No. Pages are rebuilt as images to save space, so this tool works best for scans and photos.
What if my PDF is already small?
Kindkit checks the result. If compressing wouldn’t help, it tells you and keeps your original.
Is it really free?
Yes. Every Kindkit tool is free with no limits, no watermarks and no sign-up. There is no paid version.
