Frequently Asked Questions
How much can I compress a PDF?
Typically 40–85% reduction for image-heavy PDFs. AI Analyze shows compression potential before you compress.
Which compression mode should I use?
Smart AI picks automatically. Use Email Ready for attachments under 5MB, Web for fast loading, or Lossless for text-only PDFs.
Will quality be affected?
High Quality and Print modes preserve readability. Maximum mode targets smallest size. Quality score is shown in the report.
Can I compress multiple PDFs at once?
Yes — batch upload, ZIP import, queue manager, and ZIP download for batch results.
Are password-protected PDFs supported?
Yes. Enter the owner password on upload and compression runs locally in your browser.
Is it safe for confidential documents?
100% browser processing — files never leave your device. Auto-private, no server storage.
Can I compress to a specific file size?
Yes — enable Target file size and set KB (e.g. 200KB for Aadhaar UIDAI upload). AI binary-searches quality until the target is met.
