DEFLATE is a widely used lossless compression algorithm based on LZ77 and Huffman coding. For many software implementations that support creation or extraction of ZIP archive files, DEFLATE is the only compression algorithm supported. It is also used by gzip and PNG. The PDF specification permits a variety of compression schemes, including DEFLATE, which is tagged as FlateDecode.
