Photo Quality: How to Maintain Resolution in PDFs
Keep photo resolution and clarity when converting to PDF. Learn DPI/PPI basics and compression tips.
DPI vs PPI
DPI (dots per inch) relates to printing; PPI (pixels per inch) to image resolution. Match your export to your use case (screen vs print).
Target resolutions
For screen viewing, 150–200 PPI is typically fine. For high‑quality prints, aim higher (300 PPI or more).
Avoid generation loss
Convert once from HEIC to PDF rather than HEIC → JPEG → PDF. Each lossy step may reduce quality.
Review before exporting
Rotate sideways pages and delete low‑quality duplicates to keep the final document clean.
