What to expect
- Supported inputs
- JPG and JPEG images, and any other picture: PNG, HEIC, AVIF, SVG, BMP, or GIF.
- What happens
- Each JPG is saved as a WebP at 85% quality and its full size. Lower the quality for a smaller file, or raise it to keep more detail.
- Limits
- Safari, and every browser on iPhone and iPad, loads a WebP encoder the first time, which takes a moment. Very large images can be too much for a phone's browser.
