How to convert PNG to JPG (or JPG to PNG ) in bulk?

Didnt work unfortunately

Does it work for gif to png too?

ah, though it really did change png to jpg but the size didnt really decrease png files its too large of an file for an image it takes too much space 30-70mb per image is just ludicrous multiply it by hundreds or thousands and it gonna fill up your storage rather quickly. But nice try though maybe i can still see some usage out of it in the future.

Thank you for this valuable trick!! :)

very bad tutorial it only changes the format extension without actually compressing and making the picture smaller with jpg format

This blew my mind. Now I can upload all of my photos to iCloud with ease. (it only supports JPG for some dumb reason)

You are a genious!

thank you

great guy u are

Thank you so much

freakin Awesome! wish I would have found this about 1000 pics ago! thank you so much!

This is the best thing I've found on the internet so far.

alhamdulillah, this 1min tutorial made life easy. Thanks

Perfect!

after about 2 hours of trying to search for free solutions this helped thank you

Thank you!

This only changes the extension but doesn't actually convert the pictures to a smaller jpg format.

Thank you so much! Finally, I could rename all files after wasting almost 3 hours searching for solutions!

Shit of video! You are only renaming the file, this doesn't convert. Please delete this video now.

This is wrong, dont waste your time. It only renames them to JPG not actually converting them. the file size will still be the same....

Completely useless task...don't do it

thank you ...:))))

grate job man

It works quickly and very easier

Jimbo below is correct, this does not change the .png to .jpg. I needed the smaller .jpg for printing pictures, and it does not do that.....

Seriously that best, easiest thing ever. I looked at a couple of software for this, and your video is so much easier and uses built in features. Love that. Thank you so much!

WRONG!!! simply renaming a .png file to a .jpg will not convert it since they are 2 completely different graphics formats. Yes, the DOS command line 'ren' command will successfully rename the file, and it will appear properly, but it will still be a .png file. You can tell because the file size will not change at all. If you convert a .png file to .jpg you will find that the resulting file size is tiny by comparison. This is because the simplistic jpeg format does not contain all of the graphics information present in the original .png file, such as alpha-transparency data, etc.

Sincios - You should immediately delete this video as it is incorrect and you're not helping anybody.
