Images can be brought in from a variety of image sources, and each browser supports a unique set of formats.
- Some images are decoded and converted so metadata is not preserved.
- Large images are downsampled and limited to 4096 pixels on the longest side. Any image that is larger than 4096 pixels on one side will have its longest edge downsized to 4096 pixels with the rest of the image scaled proportionally.
- Commonly supported formats include PNG, JPEG, GIF.
- Browser-specific formats include TIFF, WEBP, and others.
