What this tool does
Some websites accept only JPG, others want PNG, and photos saved from the internet are often WEBP. This tool converts between the three in your browser. Transparent PNG areas become white when you convert to JPG, so the result looks right on forms.
How to use it
- Choose your images.
- Pick the format you need: JPG, PNG or WEBP.
