When to convert
- WebP to PNG or JPG. Some editors, forms and older apps still refuse WebP. Converting gives you a file they accept. Read how to convert WebP to PNG for details.
- PNG to JPG. Photos saved as PNG are often several times larger than they need to be. JPG can cut that sharply with little visible change. Transparent areas turn white.
- JPG or PNG to WebP. WebP files are generally smaller at similar quality and are widely supported by modern browsers. Good for websites.
Quality, transparency and repeated conversion
PNG is lossless, so converting to PNG does not degrade the picture, but it cannot restore detail that a lossy source already lost. Converting to JPG or WebP is lossy: choose a quality around 85–92% for good results. Avoid converting back and forth between lossy formats, because each pass can add small artifacts. Keep your original file and convert from it when needed.
Which format should I choose?
| Format | Best for | Transparency | Compression |
|---|---|---|---|
| PNG | Logos, screenshots, graphics with text | Yes | Lossless |
| JPG | Photographs | No | Lossy |
| WebP | Websites, photos and graphics | Yes | Lossy or lossless |

Privacy and limits
The conversion is performed by your browser. Nothing is uploaded. HEIC photos from iPhones only open in browsers that support them, such as Safari; if yours does not, share the photo as JPG from the Photos app first. Animated GIFs are converted using their first frame only.
