Open-source credits

Our free tools stand on other people's open-source work. Thank you. Each project below keeps its own licence. Where a licence asks for its text to travel with the code, the file sits next to the code on this site (linked below).

Everything here runs in your browser. None of these projects receives your photos, numbers or text from our pages.
