JPG vs PNG
Compare JPG and PNG for photos, screenshots, transparency, file size, editing, web sharing, and sharp graphics.
Updated 2026-05-18
JPG and PNG are common image formats, but they are optimized for different kinds of visuals. The practical choice depends on whether the image is a photo, a screenshot, a transparent graphic, or something that will be edited and reused.
| Factor | First option | Second option |
|---|---|---|
| Best fit | Photos and complex images with many colors | Screenshots, logos, icons, and sharp graphics |
| File size | Often smaller for photos | Often larger for photos but efficient for flat graphics |
| Transparency | Not supported in standard JPG | Supported in common PNG workflows |
| Compression style | Lossy compression reduces file size by discarding some detail | Lossless compression preserves pixel detail exactly |
| Editing workflow | Repeated saves can slowly degrade a JPG | Better for intermediate screenshots, UI assets, and images that may be edited again |
| Common mistake | Using JPG for logos, text-heavy screenshots, or transparent assets | Using PNG for large photo galleries where file size matters more than pixel-perfect edges |
| Sharing trade-off | Good for fast photo sharing, email, and web galleries | Good when clarity, text edges, or transparency matter more than smallest size |
Choosing between them
Use JPG for regular photos, large image galleries, and casual sharing where smaller file size matters. Use PNG for screenshots, interface captures, logos, diagrams, icons, and transparent graphics. If the image contains readable text, flat colors, or a sharp edge that must stay crisp, PNG is usually the safer first choice.
Common examples
- Vacation photo exported as JPG
- App screenshot saved as PNG
- Logo with transparent background
- Product photo gallery compressed as JPG
- Bug report screenshot kept as PNG
FAQ
Is PNG always higher quality than JPG?
Not always. PNG preserves sharp edges and flat graphics well, but photos can become much larger without looking meaningfully better.
Which format supports transparency?
PNG supports transparency in common workflows. Standard JPG does not.
Which format is better for screenshots?
PNG is usually better for screenshots because text, interface edges, and flat colors stay crisp after saving.
Which format should I use for a website photo gallery?
JPG is usually the better starting point for large photo galleries because file size matters for loading speed.
