Use this JPEG to PNG converter to turn JPEG files into PNG right in your browser — ideal for screenshots, logos and icons and graphics with transparency. JPEG uses lossy compression and PNG uses lossless compression, so file size and quality can change.
When should you convert JPEG to PNG?
- When you need it for screenshots
- When you need it for logos and icons
- To open your files in apps that prefer PNG
- To share PNG files more easily
What happens to your file
PNG output is lossless, then run through a size optimizer: pngquant is used when it is available on the worker, with Pillow's own quantizer as the fallback. Drop the quality setting below 80 (or switch on Optimize) and the palette is reduced up front instead.
Settings this conversion runs with
| Engine | Pillow (Python Imaging Library) |
|---|---|
| Compression | Lossless |
| Optimizer | pngquant when available, Pillow quantize as fallback |
What changes
- PNG is lossless, but it cannot undo JPG. The detail your JPG already threw away stays gone — and because PNG does not compress photographs well, the file usually gets bigger, not better.
