The difference between PNG, JPG and WebP
Each image format uses a different compression method and supports different features. Picking the right one can cut file size dramatically while keeping quality.
| Format | Compression | Transparency | Strength | Typical use |
|---|---|---|---|---|
| JPG | Lossy | No | Small size for photos | Photos, social uploads |
| PNG | Lossless | Yes | Sharp edges & transparency | Logos, icons, screenshots |
| WebP | Lossy & lossless | Yes | Best efficiency (smallest) | Web images |

Frequently asked questions (FAQ)
What happens to a transparent background when I convert PNG to JPG?
JPG does not support transparency, so transparent areas are filled with a white background. To keep transparency, convert to PNG or WebP.
Can WebP be opened everywhere?
Modern Chrome, Edge, Safari and Firefox, plus the default viewers on Windows and macOS, all support WebP. Some older programs may not open it, so if compatibility matters, JPG or PNG is safer.
Does converting reduce quality?
Converting to PNG is lossless, so there is no quality loss. Converting to JPG or WebP applies lossy compression, but at 90%+ quality the loss is barely noticeable.
Are my photos sent to a server?
No. Conversion runs 100% inside your browser, and your photos are never uploaded or stored.
