Animated GIF, WebP, AVIF or PNG files are resized as a still image using the first frame; Doodleden does not keep or create animation. HEIC photos open where the browser can read them, which today means Safari 17 or later on a Mac, iPhone or iPad. Doodleden does not create HEIC or AVIF files: browsers cannot create either format, and the encoders that could are large, and for HEIC covered by patents and copyleft licences. The Image Converter explains these formats in more detail.
