File Size Reduction
Posted: Wed May 05, 2021 11:51 pm
Hi,
I recently bought Batch Photo Pro (ver.4.4) to add a simple 15 pixel border to 3,271 images.
All the images are 1920 x 1080.
After noting that most images with a border were a smaller size than the original image,
I ran a Dir on each of the 2 folders and put the results into Excel.
Results were:
Original images Images with border
2,417,198,898 1,992,401,972 Total bytes
425,168,046 sum of difference of each image (original-border images)
2,521,582 Max difference between individual images
-623,422 Min difference between individual images
So generally most images were reduced in size, but some were increased in size.
I would expect each and every image to be ONLY INCREASED in size.
Does any one have an idea what is going on?
Thanks
