Why websites use WebP
A WebP file is smaller than a JPG of the same quality, so pages load faster, especially on phones. Every current browser shows WebP, and WordPress accepts WebP uploads.
| JPG | WebP | |
|---|---|---|
| File size | Larger | Smaller at the same quality |
| Transparency | No | Yes |
| Shown by | Everything | All current browsers |
Keep a JPG for email and forms
Some email programs, forms and older apps do not accept WebP. Use WebP on websites, and send a JPG where you are not sure.
Camera data stays behind
The new files are written from the picture alone, so they carry no camera data: no camera model, no date and no location. That is safer when you post a photo online. If you need that data, keep the original as well.
When the photo itself is the problem
Converting changes the file, not the photo: it cannot fix a blurry, dark or badly framed picture. If the photo is for a CV, a profile or an application and you have no good one, a professional headshot made from a few selfies gives you one.
