Convert JPG to WebP

What goes in JPG

The classic photo format: smaller files by discarding detail your eye barely notices, which makes it ideal for photographs but poor for crisp graphics or text. It's always opaque (no transparency). Lolly tags it sRGB, can write an HDR version for bright displays, and embeds provenance and Content Credentials.

What comes out WebP

A modern web image format that packs smaller than PNG or JPG while still supporting transparency, and can be either lossless or lossy depending on what you need. Widely supported in browsers. Lolly can embed Content Credentials; it does not do HDR in WebP (the format's 8-bit).

Most tools like this are upload sites: your file goes to their server, and ads pay the bill. Lolly runs on your device, so your file stays with you.

What Lolly supports

  • Pixel raster image
  • Alpha transparency
  • Lossless quality
  • Compressed (lossy)
  • Content Credentials (C2PA)

What carries over: EXIF, XMP - The converter moves the description, author, copyright and capture date into the new file. Location stays behind unless you turn it on, and a Content Credential cannot be copied: it is bound to the original bytes.

Content Credentials survive this format
