I’ve tried to download many freeware or trial versions in order to convert lots of html files downloaded from internet into some Ebook format, such as chm or pdf. Unfortunately and surprisingly none of them is satisfactory. Some cracked commercial software do exist, but I don’t like to be a victim of Trojan.

What a luck! I found this Chinese guy (strongerhorse, or old horse in Chinese) made many useful programs and releases them as freeware. Two of them are just for the task I mentioned in the beginning.

1. HugeChm compile/decompile CHM file. (from/into html)
HugeChm_chn
2. TextForever contains a lot of functionality including html-to-txt conversion, file combination/splitting, regex search and replace.

Complex jobs could be done if you use them properly.
