Convert almost any image format into another, online, fast, and free.
Faster than launching your own graphic editor, if it even supports that format (the not-so-frequent webp, for example)
The site also converts presentations, movies, and CAD files into multiple formats. 2D is well supported, and we particularly like the vector for mart available, such as AI to SVG or SVG to AI conversion.
Freed up to 25 conversions per day.
Note: not this site in particular, but like all online sites where you upload your own material, do know what you do, the trust you can have -or not-, particularly how your data are handled and potentially kept or republished.
