Show HN: Created 60 free useful tools in one place

So I'm one of those people who like to build their own tools/utilities whenever they a) want to get something done, or b) want to learn something. c) don't want to spend ages finding a utilty and going through walls of ads.

I gradually built 66 tools, all free, fast, ad-free, and zero login.

I (and my family/friends) use these daily, so thought some of you will find it useful!

Any suggestions, improving current tools or adding new ones, please let me know.
