PDF editing & conversion
Choose a PDF-to-image resolution that keeps text readable
Avoid creating unnecessarily large images while preserving small print.
Resolution controls pixel detail
Rendering a PDF at a higher DPI creates more pixels for the same page area. That can help small text remain legible, but it also increases processing work and often the output file size. It does not restore detail missing from an embedded scan.
Start with the purpose
For a simple on-screen reference, a moderate setting may be enough. For a document containing small numbers, inspect those numbers closely before deciding. FormFile caps PDF rendering resolution at 216 DPI in this version to limit device memory use.
Test one page first
Select a representative page with the smallest text. Convert it, preview the image, and check the byte count. Increase the resolution only if the current output lacks useful detail and the destination's size limit permits more data.
Separate rendering from compression
A high-resolution image heavily compressed to a tiny target can still look poor. Adjust both settings thoughtfully. When accuracy matters, preserve the original PDF and use an image copy only if the receiving system requires it.
