Converting images with LZW might require a separate license from Unisys. Deflate Deflate or Zip compression is a variant of Lempel-Ziv that is not encumbered. That makes it more amenable to use. Deflate is supported in most PDF readers. ImagePDF can write color or grayscale image data, as well as text, using Deflate compression.
Deflate compression is lossless, meaning all data is recovered by compression.
