There is no single best image format for every job. Choose based on what the image contains, whether it needs transparency, where you plan to use it, and which formats that destination accepts.
At a glance
| Format | Good for | Trade-off |
|---|---|---|
| JPG / JPEG | Photographs and broad compatibility | Does not support transparency; repeated edits and saves can reduce quality |
| PNG | Transparent graphics, screenshots, and crisp edges | Can produce larger files for photographs |
| WebP | Web images where smaller files are useful | Check that the apps or services in your workflow accept it |
Choose JPG for many photos
JPG is widely supported and often produces compact photographs. It uses lossy compression, which means some image information is discarded to reduce file size. For best results, keep an original copy and avoid repeatedly opening and resaving the same JPG during editing.
Choose PNG for transparency and sharp edges
PNG preserves sharp boundaries well and supports transparent pixels. It is a practical choice for logos, icons, screenshots, and graphics that need a transparent background. For a large photo, a PNG can be much larger than a comparable JPG or WebP.
Choose WebP for many web uses
WebP supports both lossy and lossless compression and can handle transparency. It can be a good option when you want a smaller web image, but confirm that the site or application receiving the file accepts WebP before converting.
Convert a copy and compare
Keep the original, convert a copy, and compare both appearance and file size at the dimensions where the image will actually be used. The Image Converter can convert between PNG, JPG, and WebP in your browser.
