Batch editting the file size of images

The_KiD · 19 Jul 2007 at 09:53

We have a load of images stored in folders like this:

Archive
Archive\00\
Archive\01\
Archive\02\

etc

Thousands of them.

They are all in Tif format and some are up to 100Mb in size, even though 90% are black and white scans.

I want to find a program to go through all the folders and subfolders and reduce the quality (not the size) down to something a lot more acceptable.

There is no reason for these images to be so large.

I need to keep the images in the folders they are in keep their file names in tact too.

So does anyone know of such a program?

Hello!

Have you tried Irfan View.

It's very good, it's free for non-commercial use and it has a good batch file changing utility.

Is this for Work

? What is your job?

If the B&W Tiffs are group4 compressed then there is little you can do to reduce their size. This is extremely high ratio way to compress this type of image.

As for the larger TIF files (colour) there are a few ways to reduce the size.

Ifthey are currently uncompressed, then you could save them as LZW / ZIP but beware of compatibilty problems.

IRanview is very good. Supports batch processing.
Also check out imagemagick. It's command line, but very very powerful and if you can do a little Script you can knock this on on the head in about 5 minutes.

Get the 'Q8' version (unless you are going to be handling 16bit images)
