When the PDF to Markdown Converter 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
Headings are all level one
PDF styles rarely encode hierarchy - promote or demote # markers manually to match real structure.
Page numbers litter the text
Running heads and folios came along - strip repeated lines after conversion.
Tables are malformed
Check pipe alignment and header separators; complex tables often need manual repair.
Bold and italic are missing
Font-weight cues can be ambiguous - verify emphasis against the original.
The output is empty
Scanned source - run OCR first so text exists to convert.
Line breaks break paragraphs
Visual line ends carried over - join wrapped lines when you need clean paragraphs.
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:
- Expecting perfect heading levels
- Ignoring page furniture in the output
- Trusting emphasis detection blindly
- Converting scans without OCR
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
Are heading levels preserved?
Approximately - the tool infers hierarchy from size and weight, but manual fixes are common.
Do tables convert correctly?
Simple tables convert well; merged cells and nested layouts need cleanup.
Does it work on scanned PDFs?
Only after OCR adds a text layer to the pages.
Is my file uploaded?
No - conversion happens entirely in your browser.
