When the PDF Redaction Tool seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
I can still select text under the black box
That was an overlay, not redaction - use this tool, which removes the underlying content on export.
The black box can be moved
A movable box is annotation - true redaction becomes permanent content at export.
Hidden data remains elsewhere
Check metadata and attached files - redaction covers marked regions; the metadata editor handles properties.
I redacted the wrong area
Keep the original - redaction is permanent by design, so re-run from the untouched source.
The layout shows blank gaps
That is correct - content is gone, not hidden. Design redactions to read cleanly.
The file is still large
Redaction does not shrink files - compress afterwards if size matters.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Drawing a black box over text without removing it
- Assuming editing the box later reverses redaction
- Forgetting metadata still names people
- Redacting on a copy that was already distributed
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
Is redaction the same as a black box?
No - a drawn box can be moved or copied around. Redaction deletes the underlying content permanently.
Can redacted text be recovered?
Not when the content is truly removed at export - only overlays leave recoverable data behind.
Does redaction remove metadata too?
It targets page content - use the metadata tools to clean document properties as well.
Is my file uploaded?
No - redaction runs entirely on your device.
