TIFF compression

If you export an image in TIFF format with "compression", what type of compression does it use, and is it lossless?

Also is there any way to batch convert files to TIFF format with compression? I tried the Automator action "Change Type of Images", but there's no option there to enable compression.

Pixelmator uses losless compression. I cannot tell which compression algorithm but the most common for TIFF files is the Lempel-ZiV-Welch algorithm.

Thanks, that's good to know.

However it would appear that batch conversion to lossless tiff is not possible - even using Automator.
