When the PDF Signature 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
The signature landed on the wrong spot
Position before export - drag it into place and verify page numbers first.
It looks too small or too large
Scale it to match any existing signature lines on the document.
The recipient says it is not valid
Some jurisdictions and documents require certified e-signature platforms - check requirements before sending.
My signature is faint
Draw with a dark stroke; scan or photo uploads need good contrast to look crisp.
I signed before reviewing
Always review the final version - keep the unsigned original so corrections are possible.
The signed PDF is heavy
Compress with the PDF compressor before sending large attachments.
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:
- Signing the wrong page of a long document
- Using an illegible scribble for formal papers
- Not keeping a copy of the unsigned original
- Assuming every document accepts electronic signatures
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 an electronic signature legally valid?
In many contexts yes, but requirements vary by document and jurisdiction - certified platforms add audit trails when legal weight matters.
Can I save my signature for reuse?
Keep the drawn signature image and upload it next time - sessions do not persist it.
Does it fill form fields too?
Use the form filler for fields; this tool handles the signature itself.
Is my file uploaded?
No - signing happens entirely on your device.
