JPG vs PNG

JPG vs PNG: which image format belongs in your PDF?

Picking the right image format makes a big difference in PDF size and visual quality. JPG is usually best for photos, while PNG is better for graphics with sharp edges or transparent backgrounds.

When to use JPG

  • Photos, illustrations, and scanned pages where a small amount of compression is acceptable.
  • Large images that need to stay lightweight for sharing.

When to use PNG

  • Logos, diagrams, and screenshots with text or fine edges.
  • Images where transparency or crisp contrast matters.

In PDF workflows, you can often convert graphics to PNG and photos to JPG to get the best balance between preview quality and file size.
