What 99digest is
99digest is a collection of free online tools for everyday tasks: counting words, converting units, formatting JSON, merging PDFs, calculating percentages and much more. There are currently 90 tools across 16 categories, and we keep adding more.
Private by design
Every tool is built to run in your browser. The text, files and images you work with are processed on your own device and are not uploaded to our servers to produce a result. There is nothing to sign up for and no usage limits.
Why we built it
Most tool websites are slow, cluttered, push you to create an account or upload your files. We wanted tools that are quick, clear and respectful of your data, with a short guide alongside each one so you understand what the tool is doing.
How we keep the tools accurate
Each tool follows documented methods and is covered by automated tests. Guides include worked examples that we check by hand. If you find a mistake, please tell us and we will correct it.
Early access
99digest is in early access. Tools are free while we grow, and we are improving the site continuously. You can reach us on the Contact page.
