PDF 工具 — Frequently Asked Questions

Are my PDFs uploaded to a server?

No. All PDF processing happens in your browser. Your documents stay on your device at all times.

Can I merge password-protected PDFs?

Not directly on this site right now. Remove the password with software you trust first, then merge the unlocked files here.

What's the maximum PDF file size?

There's no hard limit — it depends on your device's memory. Most PDFs up to 100 MB work fine.

Will processing affect PDF quality?

No. Tools like merge, split, and reorder preserve the original content exactly. Compression may slightly reduce image quality within the PDF.
