IMPLEMENTATION

Viewers responsible for this format

The LZ4 frame format adds block sizes, checksums and optional content size around fast LZ4-compressed data. Anyfile exposes recognized frame metadata without expanding the payload into local files.

Common question

Is an LZ4 frame the same as raw LZ4 blocks?

No. This page covers the framed format identified by its header; raw blocks lack that self-describing wrapper.
