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.
Who runs 99digest
Sandeep Khanagwal, founder
99digest is run and maintained by Sandeep Khanagwal, a web developer with more than 15 years in the IT industry, working across WordPress, WooCommerce and SEO. The tools are developed with AI coding assistance and covered by automated tests. Read his profile.
How we make the tools and guides
Each tool follows a documented method and is covered by automated tests. We use AI to help draft the guides, glossary entries and comparisons. The numbers, examples and sources are then checked before publishing, and we keep improving them. AI-assisted drafts can still contain mistakes, which is why every page tells you how to report one.
If you find an error, please tell us on the Contact page with the page address and what needs fixing. We correct confirmed mistakes.
How the site is funded
The tools are free. To cover hosting and development, some pages show advertising from Google AdSense. Ads never appear inside a tool’s input or result area, and we do not show them on legal or information pages like this one. Read more in the Privacy Policy.
