Flatten to Image PDF — Troubleshooting Troubleshooting and recovery steps for Flatten to Image PDF. Open tool · How-to · Privacy Flatten to Image PDF troubleshooting Common issues Blank output: the source PDF may use features PDF.js cannot render (rare 3D content, uncommon fonts). Try a lower DPI first. Processing stalls at page N: browser is out of memory. Split the document before page N and flatten each half separately. Output too large: switch from PNG to JPEG, or reduce DPI from 200 to 150. JPEG at 85% quality is 2-4x smaller than PNG with minimal visual difference. Colors look wrong: some CMYK-heavy PDFs render differently in PDF.js (which works in RGB). The content is correct but colors may shift slightly. Recovery steps Retry with a smaller sample file. Refresh and run the tool again. Use an alternative workflow from /tools if needed. Check /status for current incidents. What this does not protect Troubleshooting guidance does not guarantee recovery for damaged files. It does not bypass document owner restrictions when cryptography is enforced.
