  • It accepts JPG, PNG, and WebP, one image at a time, with a 10 MB limit.
  • The library-returned blob defines output; format, dimensions, transparency, and metadata can vary.
  • The result can be the same size or larger and visual loss can occur. This flow processes in the browser and does not send the file to a server.
