ABC Tools: Free Online Tools
500+ free calculators & tools that run in your browser

Hi Product Hunt,
I built ABC Tools because most free calculator sites are covered in ads, hide basic features behind signups, and upload your data to a server.
Everything here runs in your browser. Your numbers, photos and word lists never leave your device. No account, no ads.
There are now 500+ tools across 21 categories. A few I like:
Puzzle makers: crosswords, sudoku, word searches, logic grids. Solve on the page, print, or embed on your own site.
Image tools: convert, resize, compress, crop and analyze photos without uploading them anywhere.
Poker calculators for 6 variants, with exact odds instead of simulations.
A cross-stitch pattern maker that turns photos into charts with real DMC floss colors.
The usual stuff done properly: loans, statistics, unit conversion, date math, regex, JSON.
Each tool has a short guide explaining the math behind it.
If something you need is missing, tell me and I'll probably build it.
Made a sudoku and embedded it on my blog in under two minutes, which was way easier than I expected. Love that nothing leaves the browser.
The embed feature for puzzles is genuinely useful, but it would be great if there were an option to customize the styling of embedded crosswords and sudoku to match the host site's color scheme and font, right now they probably look pretty out of place on most blogs.
