Hi. Another way to do this is by selecting the *png file, right click on it and then select save a copy, in the saving window simply name the file adding the *jpg extension and save it, that's it.  ;D

Thanks Moltke - I overlooked that detail - thankyou for pointing it out to me as I didn't know about that option.
I quite like the terminal method for changing the image format as it's so simple & direct.
I mentioned batch files in post #1 - do you know if Ristretto can also convert the format of those too?

Cheers

You're welcome! I do agree with you about the terminal method being simpler and direct, I only thought of sharing the "save a copy" method with ristretto too, not because I think it's better but because it's possible. Regarding your question about Ristretto being able to convert between formats, according to this manual https://docs.xfce.org/apps/ristretto/getting-started seems it's not meant for converting images. However, I did changed the *.png extension to *.jpg but it didn't recognize it as a *.jpg img while image magick did. If I right click the *jpg img and check its properties it does says it's a *.jpg file though.

Regarding whether "save a copy" in Ristretto actually converts the file:

I don't have the system in front of me. But if a .PNG is converted to a .JPG, the .JPG file should be noticeably smaller. So if the two files (before and after) are exactly the same size, then I'm pretty sure no conversion took place.

Can't say for sure about Ristretto, but I do know that Mirage will convert from one file type to another when choosing to "save as" and then change the extension type.
