JPG vs PNG: What's the Differenceand Which Should You Use?
A side-by-side comparison of PNG and JPG — file size, image quality, transparency and use cases — with a direct recommendation and conversion options.
Use JPG for photos — lossy compression keeps file sizes small and works great for continuous-tone images. Use PNG when you need a transparent background, crisp text and line art, or screenshots — lossless quality at the cost of larger files. One rule: photos → JPG, graphics/transparency → PNG.
PNG vs JPG at a Glance
| Dimension | PNG | JPG |
|---|---|---|
| Compression | Lossless — no quality loss | Lossy — smaller file size |
| Transparency | Supported | Not supported |
| File size | Larger | Much smaller |
| Sharp edges / text | Crisp, no artifacts | Can produce blocking or fringing |
| Color-rich photos | Large files, no advantage | Efficient compression, ideal choice |
| Re-saving after edits | No quality loss each save | Loses a little quality every save |
Transparency: PNG's Irreplaceable Advantage
PNG supports an alpha transparency channel, allowing image backgrounds to be fully transparent. When layered over any background color, the edges remain perfectly clean. JPG has no transparency support whatsoever — save a transparent image as JPG and the transparent areas are filled with a solid color (usually white or black).
These assets must use PNG
Logos, icons and stickers with transparent backgrounds, crisp UI screenshots and any graphic containing text all belong in PNG. Using JPG for these will introduce fringing, compression artifacts and the loss of transparency.
Which Format to Use and When
Digital photos / landscapes / portraits
Use JPG. Continuous tones compress efficiently — the quality difference is barely visible, and the file is much smaller.
Transparent backgrounds / icons / logos
Use PNG. The only format with full transparency support and clean edges.
Screenshots / text-heavy graphics
Use PNG. Sharp text and line art stay crisp without compression artifacts.
Web performance is a priority
Consider WebP or AVIF — smaller at equivalent quality — with JPG/PNG as fallbacks.
For color-rich photos, JPG wins: smaller files, perfectly adequate quality. For transparency, crisp text or screenshots, PNG wins: lossless and artifact-free. Saving a photo as PNG bloats the file for no benefit; saving a transparent image or screenshot as JPG causes fringing and strips the transparency. Match the format to the content.

PNG vs JPG FAQ
For crisp graphics and text, yes — lossless means no artifacts. But for photos, PNG just means a bigger file with minimal visible quality difference. Photos belong in JPG.
No. JPG's lossy compression permanently discards detail — converting to PNG just wraps that already-degraded image in a lossless container, making the file larger without recovering anything.
Photos in JPG, transparent graphics and icons in PNG is a solid baseline. For maximum performance, prefer WebP or AVIF with JPG/PNG as fallbacks.
PNG-8 is 256-color indexed — smaller, suitable for simple flat graphics. PNG-24 is full-color with transparency, suited for complex images. Most export tools default to PNG-24.
