Overview

JPG to WebP creates a WebP copy of a JPEG image through the shared browser-local image worker path. The source image is checked for bytes, dimensions, and pixels before decoding.

Use Cases

  • Prepare a WebP copy of a JPG for modern web publishing workflows.
  • Create a browser-encoded WebP image without installing desktop software.
  • Keep source image bytes on the device while testing the image conversion path.

Limitations

  • The final WebP encoder behavior depends on browser support.
  • Input bytes, dimensions, and total pixels are capped before decoding.
  • This preview processes one still image at a time.

FAQ

Does this JPG to WebP converter upload my image?

No. The selected JPG is read by the browser and converted through a local worker for this preview tool.

Does every browser support WebP output?

The preview checks local browser encoding support and returns a clear unsupported-browser error if WebP output is unavailable.
