When the PDF Cleaner 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
The file is corrupted after cleaning
Start from the original - a damaged source can fail when restructured; repair first if needed.
Savings are small
The document was already tidy - the compressor targets images where real weight sits.
My annotations disappeared
Stray annotation cleanup may remove unused marks - export after confirming visible ones survive.
Personal data is still there
Cleaning targets structure, not privacy - use metadata and redaction tools for data removal.
Something renders differently
Rare dependency was removed - re-run on the original without aggressive cleanup.
Signature broke
Any change invalidates signatures - clean before signing.
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:
- Cleaning a signed document
- Expecting cleaning to fix corruption
- Cleaning repeatedly for more savings
- Assuming cleaning removes personal data automatically
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
What kind of junk gets removed?
Unused objects, orphaned data streams, redundant fonts and leftover intermediate artefacts.
Is cleaning safe?
On healthy files yes - keep the original until you have verified the cleaned output.
Does cleaning remove metadata?
Not automatically - the metadata tools handle document properties explicitly.
Is my file uploaded?
No - cleaning happens entirely in your browser.
