PNG vs JPEG — When to Use Each
PNG is better for: - Screenshots and UI captures (sharp text edges) - Graphics, logos, icons with transparency - Images that will be further edited - Illustrations with flat colors
JPEG is better for: - Photographs and real-world images - Web images where page speed matters - Social media sharing - When file size is more important than preserving sharp edges
Transparent PNG to JPG — Handling Transparency
JPEG doesn't support transparency. When you convert a transparent PNG to JPEG:
Default: PDFBro fills the transparent areas with white, the standard background for most use cases.
If you need a different background color: 1. Open the PNG in any image editor 2. Create a new layer below with your desired background color 3. Flatten and export as JPEG
Or: If you need to keep transparency, save as PNG or WebP instead of JPEG.
Pro Tips
- 1
For website optimization: screenshots and UI images → keep PNG and compress it. Photos → convert to JPEG or WebP.
- 2
Don't double-compress: avoid saving a JPEG as PNG then converting back to JPEG. Each lossy encode cycle degrades quality.
