Batch convert multiple screenshots in PNG to JPG

Question

I have multiple screenshots in PNG format to print but cannot get them converted to JPG on my Galaxy S6 phone.

How can I convert multiple PNG screenshots to JPG photos so I can print them on a photo website?

Answer 1

imagemagick

You can use mogrify (or convert) from imagemagick

To install it, use the following command:

sudo apt install imagemagick 

Then go to the folder with the PNGs and:

mogrify -format jpg *.png

Notes

• You could also rm *.png
• Also useful to convert all to a single PDF: mogrify *.jpg naughtyphotos.pdf
• Format shouldn't be an impediment to print your photos.
• You may also want to remove all the EXIF metadata content.
• Another way is with ufraw-batch
