Resizing multiple images from GIF to JPEG

Here we will learn how to convert multiple images from one format to another.
Make a folder C:\input and put source images inside.
Download the famous program IrfanView (about 1,5 MB) from their site http://www.irfanview.com/ .
Start the program (see screenshot 1).
From the menu choose File->Batch Conversion/Rename
Set up the options according to screenshot 2.
Options are easy to understand:
-choose the source folder
-press the button "Add аll"
-choose the output format from "Output format:"
-choose the destination folder (in our case this is C:\input )
-press the button Start Batch .

Images are ready.

If we want additional options like text over the image or a sharpening mask, then we can press the button "Advanced", which is just besides the section for output images.
Good luck.
