Frequently asked questions
Does editing metadata change the visible content?
No — only the file properties change. Text, images and layout stay identical.
Will search engines pick up new keywords?
Metadata is one of several signals search engines use for PDFs. It helps but doesn't guarantee ranking on its own.
Is this tool safe to use with confidential files?
Yes. Every file is processed locally inside your web browser using JavaScript and WebAssembly. Nothing is uploaded to a server, stored, or shared — so contracts, invoices, medical records and personal documents stay 100% private on your device.
Is it really free? Are there any limits or watermarks?
Yes, it's completely free with no sign-up, no daily limits, and no watermarks stamped on your output. Process a single file or hundreds — the only limit is your device's memory.
