What This Tool Does
This tool converts a RAR archive to the 7Z format. It extracts every entry from the RAR using a real archive engine, then packs the contents into a 7Z archive with LZMA compression and offers the result for download.
Converting to 7Z is useful when you need to standardize on one archive format or take advantage of 7Z compression on systems that support it.
How It Works
The RAR is decompressed entry by entry into a staging area, then every entry is written into a new 7Z archive using the engine's LZMA compressor. The resulting 7Z is opened again to confirm it is readable before download.
