Formats suit different kinds of images
JPEG is widely supported and often useful for photographs, but it does not preserve transparency and uses lossy compression. PNG supports lossless encoding and transparency, which can suit interface graphics or screenshots, although the file may be larger. WebP supports lossy and lossless options and transparency, but compatibility requirements should still be checked for the destination.
No format is best for every asset. The source, visible detail, transparency, and audience's software all matter.
Check the exported version
Format conversion may change compression artifacts, transparency, or file size. Keep an untouched source file and inspect the output at its intended display size. A browser's export support can vary, so make sure the resulting file has the format you expect.
The image conversion utility creates a local preview and a downloadable copy for common web formats. Use it as an export step, then verify the file in the application or upload form where it will be used.
