Why convert JPG to WebP?
WebP often beats JPG on size at similar visual quality and can keep an alpha channel if you need one later. Use this when the destination supports WebP — modern browsers do.
What changes in the file
- Both formats are lossy; a fresh encode may change fine detail and file size
- WebP can keep an alpha channel for later edits
- You can resize, adjust quality where relevant, and strip EXIF on export
- Conversion runs on this device — the file is not uploaded
How to convert JPG to WebP
- Drop one or more JPG files onto the converter (or pick them from disk).
- Confirm the output is set to WebP, then adjust quality, size, or metadata if needed.
- Download the converted WebP file — processing never left your browser.
About JPG
JPG (JPEG) is a lossy raster format built for photographs. It shrinks file size by discarding detail the eye is less likely to notice, which makes it a default for cameras, email, and the open web.
About WebP
WebP is a modern web image format from Google. It can encode lossy or lossless images and supports transparency, often beating JPG and PNG on size at similar visual quality.
