What this tool does

What goes in
Reads PDF. One file at a time.
What comes out
You get PDF.
What happens to quality
Vector or page description becomes pixels. Nothing gets blurrier, but the result no longer scales freely — pick the size before you export.
Where it stops
Password-protected files cannot be opened. Very large files are limited by your device's memory, not by a server quota.
Redact a PDF
Rasterises only pages with selected redactions, burns the black areas into their pixels and copies untouched pages directly. The rebuilt document excludes source metadata, attachments and active document actions.

Good to know

Frequently asked questions

Can hidden text be recovered after redaction?

Not from a redacted page: the page becomes an image and each black box is burnt into its pixels. Review the result before sharing because the change cannot be undone there.

What remains unchanged?

Pages without a selected redaction are copied directly. Document metadata, attachments, JavaScript and automatic actions are removed from the rebuilt file.

What files can I use here?

Reads PDF. One file at a time.

What do I get back?

You get PDF.

Does the file lose quality?

Vector or page description becomes pixels. Nothing gets blurrier, but the result no longer scales freely — pick the size before you export.

When does it not work?

Password-protected files cannot be opened. Very large files are limited by your device's memory, not by a server quota.

Does the text stay searchable?

Yes, and compressing keeps it that way too: by default only the embedded photos are recompressed, while text, fonts and layout stay untouched. Merging, splitting and adding images move the pages as they are. Only the second compression method redraws every page as an image — then the text becomes part of the picture, and the tool says so before you start.

Can password-protected PDFs be opened?

No. A PDF locked with a password cannot be read in the browser, and the tool says so rather than producing an empty document. Remove the protection in the program that created the file first.
