LZIP Compress
Compress text or encoded binary data to LZIP online and output the result as Hex or Base64. Read more
What is LZIP compress?
LZIP compresses a single byte stream into one or more members with integrity information. This tool creates a complete .lz stream from text or encoded bytes; it does not create a multi-file archive and does not store filenames.
How to use this tool
Enter text or encoded bytes, select the byte encoding, choose preset level 0–9, and output the LZIP bytes as Hex or Base64. Hex and Base64 input are decoded before compression. Use LZIP Decompress to restore the result.
Choosing the right format
Base64 is more compact for transporting binary data as text; Hex is easier to inspect. Higher presets increase CPU use and memory. Prefer level 6 unless you have a specific reason to choose otherwise.
Important limitations
LZIP is not encryption. Integrity checks detect accidental corruption but do not authenticate the sender. Already-compressed or short data may grow. Browser memory limits make native tools preferable for large input.
Frequently asked questions
Why can another program not open the result?
Decode the Hex or Base64 result into bytes and confirm the receiver expects the .lz container, not XZ, LZMA-Alone, or a .tar.lz archive.
Are my files uploaded?
No. Compression runs locally in the browser. For files or folders, use LZIP Create.
