Troubleshooting
Fixes for slow tools, files that won't open, conversions that look different, and downloads that don't start.
A tool is slow or stops responding
Close other memory-heavy tabs and try again. For very large documents, use Split PDF first and process the parts separately. See Large documents.
A file won't open or shows an error
The PDF may be damaged. Run Repair PDF, then use the original tool on the repaired file. If the file is password protected, see Password-protected PDFs.
A converted document looks different
Complex layouts, unusual fonts and scanned pages don't always convert perfectly. For scanned documents, run OCR first so the text can be recognized, then convert.
The download didn't start
Check whether your browser blocked the download or asked where to save it, and make sure your device has enough free space.
Something still isn't right
Reload the page and try again. Reloading clears files from the tool, so download any results you want to keep first.
