Frequently asked questions
Is my PDF sent to a server?
No. All PDF tools run in your browser — the file never leaves your device.
Is there a watermark or limit?
No watermark. Very large files (100+ pages) can be slow on phones — a computer works best.
Do password-protected PDFs work?
Unlock the PDF first — these tools cannot open password-protected files.
