Frequently Asked Questions About PDF Compression
Q.Will compressing my PDF reduce text sharpness or readability?
No. Our compression engine optimizes document structure, removes duplicate metadata, and compresses PDF cross-reference streams without degrading typography or vector lines.
Q.Why should I reduce my PDF file size?
Most email clients (like Gmail, Outlook, Yahoo) cap attachment sizes at 20MB to 25MB. Government portals and university submission forms often enforce strict 2MB to 5MB limits.
Q.Do I need to sign up or install software?
No registration, software, or browser extensions are required. Simply drop your document and download the optimized version immediately.
Q.Are my tax returns or private contracts safe here?
Yes. Files are never uploaded to any cloud server or database. The compression happens entirely in your local browser sandbox.
