About XPRESS LZ77+Huffman Decompress
Decompresses data using the XPRESS LZ77+Huffman algorithm (MS-XCA section 2.2). The uncompressed size must be known in advance, as it is from the WOF chunk table or WIM header, so it is taken as an argument.
Input: binary bytes. Output: binary bytes.

- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
