Questions
Are my PDFs uploaded?
No. PDF Desk opens and writes the file with JavaScript inside your browser tab. Nothing is sent to a server, so it is safe for contracts, IDs and bank statements.
How much smaller will my PDF get?
Scans and photo PDFs usually shrink by 60–90%. PDFs that are mostly text are often already small and may not get smaller.
Why is the text not selectable after compressing?
To shrink the file, each page is re-drawn as a compressed picture. Keep the original if you need to copy text.
