How it works

OpenToola decodes the image in your browser, draws it to a canvas and exports JPG, PNG or WebP. HEIC/HEIF and TIFF are decoded locally; animated images export the first frame.

Steps

  1. Select any supported image.
  2. Choose the output format.
  3. Adjust quality if needed.
  4. Convert and download.
