The CHM file format is a binary format that uses the LZX algorithm to compress the HTML data found in the file. The format supports full text searching, indexing, and table of contents, among other useful features.
The RAR archive format supports compression, file spanning, and error recovery. Compression is carried out using a prediction by partial matching algorithm and the lossless compression algorithm LZSS. The RAR file format has a range in file size from as low as 20 bytes to 8 exbibytes less 1. It also supports AES encryption at 256bits as well as the CRC32 checksum and BLAKE2 file hash algortihms.
Upload your document file in the CHM format from your device, Dropbox, or Google Drive.
Select RAR as the output format and click Convert. Adjust optional settings if needed.
Download the converted archive file. Each file stays available for up to 5 downloads.
