JPG to WebP
Convert JPEG photos to WebP in the browser to cut page weight. Adjust quality, then download the .webp without uploading.
Pick a .jpg or .jpeg when you want WebP for a photo-heavy page. This converter accepts JPEG only, not PNG screenshots.
Encoding uses canvas in this tab. The photograph is not sent to a conversion farm.
How to use
- Choose a JPEG file.
- Set WebP quality and process.
- Download the .webp and compare the byte size.
How it works
JPEG photos already use lossy compression. Re-encoding to WebP at a similar visual quality often yields fewer bytes for the same pixel grid.
Quality below 1.0 is lossy WebP. Very high quality may not beat a well-tuned JPEG, so compare the download size on your own shot.
Examples
Hero photo
A 1600-pixel JPEG banner often drops 20 to 40 percent in bytes as WebP at quality 0.8.
Gallery
Batch one image at a time in the tab, then replace .jpg references in HTML with .webp where browsers allow.
FAQ
Can I drop a PNG here?
No. Use the PNG to WebP tool for graphics and screenshots.
Will animation survive?
This path encodes a still frame via canvas. Animated JPEG is not a typical input.
Is WebP smaller every time?
Usually for photos, not always. Compare the compressed size on the page.
Does conversion leave the browser?
No. JPEG to WebP is local.
