Power Batch freeware does batch convert, resize, rename, crop, rotate, adjust, and print out your watermarked photos. Conversion is performed among JPEG, TIFF, GIF, BITMAP, PNG and JPEG2000.
Resizing can use one of the 11 resampling filters. Renaming template uses a combination of EXIF date/time, auto number and any custom string. You create your watermarks the same way as in Photo Watermark Professional and print your watermarked photos in batch mode.
