Batch Convert Jpeg Size

The CDIL uses an action in Adobe Photoshop to run a batch process to produce 300 dpi Jpeg copies of the full resolution processed Jpeg files. The 300 dpi Jpeg files are smaller in size and suitable for web publication.

Note: Non-batch related instructions for processing material can be found on the Processing Images and Processing Documents pages.
