FAQ
How much can I reduce my PDF size?

Text typically stays sharp. Images may lose some quality at higher compression. Choose "Low" if image clarity is important.

Up to 20 PDFs, 50 MB each.
Is my PDF secure?
Your file is uploaded securely, processed, and then deleted after processing. We donโt store your documents long-term.
Can I compress password-protected PDFs?
Password-protected PDFs may fail to compress. Remove protection first if possible.
Does compression remove any content?
No. Compression reduces file size by optimizing resources (like images) and removing redundant data.
