Frequently Asked Questions

Redact vs black highlight — different?

Both only cover text visually: highlights draw over text that copies out underneath, and this tool paints opaque black rectangles over the selected pages or areas — the underlying content stays in the file. For permanent removal, use a tool that strips content streams.

What should I redact?

Names, IDs, account numbers, prices, and signatures per your policy. Search all occurrences — one missed instance on page 47 defeats 46 redactions.

Can redaction be reversed?

Treat it as one-way visually, but not as removal: the black regions hide content on screen and in print, yet the text stays in the file and can be recovered. Keep an unredacted master under access control; distribute only redacted copies.

Does redaction upload my file?

No — redaction runs locally in your browser. Only the final save touches the network — downloads are unlimited.
