How to use Image convert

  1. 1. Open an image. PNG, JPEG, WebP, GIF (first frame).
  2. 2. Pick the target type. Browser must support encoding (WebP).
  3. 3. Convert and download. Local only.
  4. 4. Preview. Object URL in the tab.

About this tool

Format conversion without an upload. Canvas re-encodes the bitmap as PNG, JPEG, or WebP. JPEG cannot keep alpha; expect a matte.

WebP

Needs a browser that implements toBlob('image/webp').

Animated GIF

Only the frame the browser draws.

Code examples

MIME
