JPG to WebP Converter

Your JPG is already lossy. The converter decodes it and encodes a new WebP at quality 0.92, which is lossy as well, so the picture goes through compression twice. At this setting the extra loss is small, but it does add up if you keep re-converting copies of copies.

Keep your original JPGs, and convert from the best version you have, ideally the file straight from the camera or phone.

The result line shows the old and new size side by side. Don't assume the WebP is smaller. A JPG that was already squeezed hard, such as an image downloaded from social media, can come out about the same size or even larger, because 0.92 is a fairly high setting for a file that started at low quality.

There's no quality slider on this page, so if the WebP is bigger, keep the JPG.

The WebP is built from canvas pixels, which carry no EXIF data. GPS coordinates, camera model, lens and capture time are all left behind. That's useful when you're publishing photos taken at home, but it's a loss if you rely on the capture date to sort your library.

Photos stored sideways with an orientation tag are rotated by the browser while decoding, so the WebP is saved upright. The file stays on your device the whole time.

1. Start with the original photo.
2. If it's wider than the space on your page, shrink it with the Image Resizer. Note that the resizer saves JPG input as a new JPG at 92%, which adds one more lossy step.
3. Convert the resized JPG here.
4. Compare the size line, and keep the JPG as a fallback if your platform needs one.

Converting to WebP doesn't change the width or height, so resizing is what makes the big difference for oversized photos.
