|---|---|---|
| Compression | Lossy | Lossy or lossless, your choice |
| Transparency | No | Yes |

| Opens in | Everything | All modern browsers, Windows 11 Photos, macOS Preview |
| Typical size | Baseline | Usually smaller at the same visual quality |
Does WebP lose quality?
Lossy WebP throws away detail your eye is unlikely to notice, the same idea as JPG. Lossless WebP keeps every pixel exactly. For a photo that is already a JPG, a quality of 80 to 90 normally looks identical while the file gets lighter. That is the usual reason for the WebP vs JPG size gap.
WebP browser support
Chrome, Edge, Firefox, Safari, Opera and Samsung Internet all display the WebP format today. Older desktop programs and some email clients may still not open it, so keep your originals if you share files outside the web.
JPG to WebP without losing quality
Good results depend on picking the right mode for the picture. These tips help you convert JPG to WebP without losing quality you care about, whether the job is JPG to WebP high quality for a portfolio or the smallest file for a banner.
Pick a quality between 80 and 90
For JPG to WebP lossy output, move the quality slider to about 85 for most camera photos. Zoom up to 16× on the result and use hold to compare (the B key) to check skin, sky and fine text. Drop the value only if the file is still too heavy.
What about lossless?
JPG to WebP lossless keeps the decoded JPG pixels exactly, but the file is often larger than the JPG you started with. Use it only when a later edit must not add another round of compression.
Camera data
A web page does not need the camera data, and removing it keeps location out of public images. The option to keep date & camera applies to JPG output, so JPG to WebP keep EXIF is not offered; your WebP files come out clean.
Set a longest-side limit
A 4000 px image is too big for a blog column. Set the longest side to 1920 or 1200 px while you convert, a simple JPG to WebP resize that makes the file much smaller. For exact pixel sizes or social presets, use the image resizer first.
Check the size after converting
Every result shows the JPG to WebP size before and after, plus totals for the batch. If one file came out larger, it was probably already well optimised; keep the original for that one.
