Formatswap.com is an excellent online tool for converting files. I've used it several times, and I'm really impressed with its performance. The website is user-friendly and offers a wide range of conversion options, making it incredibly versatile.
Does a good job at converting image files. I have not tested the other file conversions as they aren't available yet but I wouldn't be surprised if it worked just as well. No "premium" bs seen on other file conversion sites.
I'll be adding this to my bookmarks!
I like this tool because you do not need to download any software to be able to use it. You just load up https://formatswap.com/png2jpg and drop your files. Then they automatically download as png. My favorite part is that it works on all operating systems including mobile.
