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
File Size Reduction
Hi,
This happens because you save your output images as JPG/JPEG which is a lossy image format. This means some data will be lost each time you re-save the image. No matter if you save with BatchPhoto or Photoshop or any other editor.
There are two solutions to this problem:
* In Step 3 select the Output Format as JPG, then click on Settings and adjust the Size/Quality slider to get an image size close to the originals;
* Save your images in a lossless image format like PNG or TIF with much bigger file sizes.
Here are more details about image formats:
