Redact PDF

1 Open this page and add the file. Redact PDF starts in the browser you already have open.2 Run the tool. If this version cannot do the job honestly, it says so instead of inventing a result.3 Download the file that was built on this device. Closing the tab drops the bytes.
About this tool
Redact PDF should remove the underlying text, not paint over it. A white rectangle leaves the words in the file, where someone can copy them. This version will not draw that rectangle and call it redaction. Until a pass can delete the text and then show that it is gone, there is no button that claims to redact. Do not upload a sensitive file to a website to learn this the hard way.
Redact PDF stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
- No upload: the file stays here, and you are not offered a false black-box download.
- Speed: the file does not travel to a server and back, so the wait is only the work itself.
- Quality: the original is kept when the new file would be worse or is not actually smaller.
FAQ
Does “Redact PDF” upload my file?
Redact PDF reads the file in this tab. There is no upload step and no account.
What will “Redact PDF” actually change?
Nothing is marked redacted in this version, because that mark would be a lie without removing the text.
When is “Redact PDF” the wrong job?
Highlighting, a white shape, or a crop is the wrong tool for names, account numbers, or health details.
How do I check the result of “Redact PDF”?
If you can still select the words or search for them, they were not removed. Do not send that file.
Can I run “Redact PDF” with Wi-Fi off?
Load this page, then turn Wi-Fi off and run Redact PDF again. A finished result is the proof that the file was not sent anywhere.
