Most conversion problems fall into a handful of patterns. The notes below draw on the support guidance archived for the Quick PDF tools, rewritten as general advice that applies to most desktop converters.
Keep a copy of the failing file
When a conversion goes wrong, the original PDF and the faulty output are the two most useful pieces of evidence. Hold on to both. If you ever need to ask a vendor or a colleague for help, sending the pair lets them compare the source and the result directly, which usually gets to the cause faster than a written description.
Check the log and the summary
Some converters write a short summary after each run and keep a log file. If a job fails, the log normally names the page or the feature that caused the stop. The program’s built-in help file is the next place to look, because it lists the option combinations that are known to conflict.
Common symptoms
- Blank pages in the Word file. Output modes such as “text only” and “formatted text” discard pictures on purpose. Switch to a flowing-text or “as is” mode if the images matter.
- Locked PDFs. A document protected with a master password can only be converted if you know the password. The program will ask for it and continue once it is entered.
- Scanned pages that come out as pictures. A scan is an image, not text. Use the OCR option so the characters become editable.
- Activation problems. Firewalls and security software sometimes block the one-time activation check. Ask a network administrator to allow it, or pause the antivirus for the few seconds the check takes.
- A “file is missing” message. Reinstalling the program normally restores the missing component.
- Poor print-outs. Open the page setup and make sure the paper size matches the printer, for example Letter or A4.
Updates and licences
Keep the software current, since new releases often fix font and layout edge cases. Registration keys are typically tied to a single computer, so a reinstall on a different machine may need a fresh key from the vendor.
