About converting JPG to WebP
This converts JPG images to WebP entirely in your browser. JPG is the universal format for photographs, with small lossy files and no transparency. WebP is a modern format that is usually smaller than JPG or PNG at the same quality and supports transparency, though a few older programs cannot open it. Converting JPG to WebP is a common way to make photos smaller for a faster website. The conversion runs on your device using the Canvas API, so your images are never uploaded.
How it works
Your JPG image is decoded and redrawn onto an HTML canvas, then re-encoded as WebP. Because WebP is a lossy format, a quality slider lets you balance file size against detail. The pixel dimensions are kept the same — only the format changes. WebP supports transparency, so transparent areas are preserved.
Good to know
A few older programs and systems still cannot open WebP, so keep a JPG copy where broad compatibility matters.
Privacy
Conversion happens entirely in your browser with the Canvas API. Your JPG images and the WebP result are never uploaded or stored. Re-encoding also strips any embedded metadata, such as camera info or GPS location.
