Single Page Helpers

Inspired by Simon Willison's collection, I am also building a small collection of small helpers for common tasks that I usually get done using some free web tool. In this collection I list a series of webpages, each completely self-sufficient, that can be used to perform a basic task like cropping an image, generating a QR code, or visualizing timezones. All the tools are open-source, so feel free to copy them for your own personal use.

You can find them here: Single Page Helpers.
