It is easy to set up a batch job using multiple methods on a large amount of files.

With Rename Photos you can construct new file names by adding, removing, replacing, changing case, or giving the file a brand new name based on known information about the file.

Before performing the operations on the files you can verify that the output will be correct and if you perform the rename and regret it, you can undo the complete batch.

Some of the Features
-> Rename multiple files quickly: according to many flexible criteria
-> Convert file formats: convert image formats with a click.
-> Rename files in many ways: add, replace, add capture and other date, insert text into file names, Convert case, add numbers. Remove or change file extensions.
