About Ontool
Ontool is a free online toolbox for the small jobs that should not need an account, a subscription or a sign-up wall. It lives at ontool.xyz.
At a glance
- 18 practical tools in one place. Writing, images, video, barcodes, email checks, invoices and money maths.
- Most work happens in your browser. 15 of the 18 tools process files on your device; only Temp Mail and the two AI tools use a server.
- No ads, no tracking cookies, no paywall. Every tool is free to open and use, and nothing is hidden behind a trial.
- An account is optional. Signing in only ties account settings together; every tool still works without one.
What Ontool is
Ontool is a collection of focused online tools for tasks that come up every day: editing Markdown, compressing an image, extracting frames from a video, making a QR code or barcode, checking a disposable email address, creating an invoice, or working through a fee or revenue calculation.
The goal is simple: open the tool you need, use it, and get on with your day. You do not have to create an account, start a trial, enter a card or install anything. Browse the full toolbox to see everything that is available.
How the tools work
Most Ontool tools run entirely in your browser. Your files stay on your device, are not uploaded to Ontool, and disappear when you close the tab. The browser-first approach keeps the tools fast and keeps your documents private.
A few tools need a server to do their job: Temp Mail receives messages, and Explain My Report and Parent Translator send a document to an AI model for processing. Those tools explain their limits on the page, and the privacy policy describes what reaches the server and what does not.
Why it is free
Ontool is built as a small, independent project rather than an ad-supported content site. There are no advertising embeds, tracking pixels or paid tiers. The AI tools have a daily free-use limit so that server costs stay manageable, but the browser tools do not need an allowance.
We do not sell personal data, and we do not keep a history of the documents you process. The terms of use set out the practical limits and the few rules for using the service.
Who runs Ontool
Ontool is an independent project operated by the team behind this site. If you have a question, found a bug, or want to suggest a tool, email ontoolsupport@gmail.com. Include the tool you used and, if relevant, the browser and device so the issue can be reproduced.
