How do i use irfanview 3.99 to change the file size of pictures?

Several options:

Save as menue, decrease colors, enhance colors ....



There are a some mime types ( file endings ) that permit e. g.

reduced quality ( either less colors or better compression )

use them (e. g. png, gif, jpg ...) with reduced values.



Example png or gif with reduced number of colors.

(for a number of things about 40 colors, else try 4 good values)



jpg increased compression.

( for a number of things about 70%, else try 4 good values )



Always shop around and try 4 a value that suits You needs.How do i use irfanview 3.99 to change the file size of pictures?
Open the image you want to resize



Go to 'Image' at the top



Click on 'Resize/Resample'



Here you can either 'Set New Size' by specifying the exact width and height in pixels, or choose 'Set New Size as Percentage of Original' - I usually go with the second option.



If you don't like the changes you made go to Edit and Undo and try again.
