Why convert JPG to PNG?
JPG is excellent for photographs because its lossy compression gracefully discards detail the human eye barely perceives. But that same compression introduces blocky artifacts around hard edges and text — exactly the things you want to preserve in logos, screenshots, and UI mockups.
PNG uses lossless compression. Once you re-save a JPG as PNG, every subsequent edit is non-destructive: you can crop, recolor, and re-export without watching the quality slowly bleed away. PNG also supports a full 8-bit alpha channel, so you can drop your image onto any background and the edges will composite cleanly.
The trade-off is file size — a PNG of a typical photograph is usually 3–5× larger than the equivalent JPG. For photos destined for the web, WebP is usually a better target. But when you need transparency or pixel-perfect fidelity, PNG is the right answer.
Common use cases
- Adding transparency to a photo background
- Preserving screenshot text and UI elements
- Preparing images for further editing in Photoshop or GIMP
