Just want to share a small Javascript tool to visualize which image format (type) that has best quality with the lowest file size.
Notes:
- For my usual work, normally I use this to see how much JPG compression I need to apply to accept the quality (before it is pixelated).
- WebP is often giving better image quality with same filesize.
- There is not one image format that always gives the best result, depending on the image itself.
