JPG to WebP
At matching visual quality, WebP typically produces meaningfully smaller files than JPG, which is why it's become the default format modern websites serve photos in.
This is a common step in speeding up a website's page-load time, since smaller image files download faster with no visible quality difference.
As a rule of thumb: stick with JPG when you need it for photos, where small file size matters most, and convert to WebP when web pages that need small, fast-loading images is what you actually need instead. Converting also gains you transparency support, which JPG doesn't have.

Frequently asked
- Is my JPG file uploaded to a server?
- No — the conversion runs entirely in your browser using the Canvas API. Your image never leaves your device.
- What's the maximum file size?
- There's no hard limit, but very large images (over ~50 megapixels) may be slow to process since everything runs on your device rather than a server.
- Can I convert multiple files at once?
- Yes, the converter above accepts multiple files and lets you download them all at once as a zip.
