COMPRESSING JPEG (JPG) IMAGES

When we find ourselves involved in groups where a lot
of email is generated and when that email contains
many images it is only good manners to reduce the size
of the image in KB's, to save on huge downloads for
the receiving party.

To compress a .jpeg (.jpg) image
go to FILE >>> SAVE AS >>>

This window below will appear..
Name your file
Click the 'down' arrow to the right of the 'Save as type:' box
Click on 'JPEG - JFIF Compliant.....'

THEN click on the 'OPTIONS' tab

This window will then open
Ensure the 'Encoding is set to STANDARD
Set the COMPRESSION FACTOR to somewhere between 25 and 50
Click 'OK'

These are examples of the different Compression factors on
the same Image.

From left to right
Image 1 = 25% Compressed (10.3kb)
Image 2 + 50% Compressed (7.5kb)
Image 3 = 75% Compressed (5.5kb)

Note the distortion the more the image is compressed
