Know the limits

Local does not mean unlimited.

Browser processing protects the file from an upload workflow, but the browser, device, output format, and selected settings still matter.

  • JPG does not support transparency, so transparent pixels must be flattened.
  • Lossy conversion can change fine detail and color.
  • Animated WebP is converted as a still image using the browser-decoded frame.

Clear answers

WebP to JPG questions.

Why do I need a background color?

WebP can contain transparent pixels but JPG cannot. The selected color is placed behind the image before JPG encoding.

Is the WebP uploaded?

No. The browser decodes the WebP and creates the JPG locally on this device.

Will the JPG always be smaller?

No. Output size depends on the image, source encoding, chosen quality, and dimensions. The tool reports the exact result.
