About OnDevice Tools
Free file tools that run in your browser. Your files never leave your device.
Why we built it
Converting a photo or joining two PDFs should be simple. But most free online tools ask you to upload your file to their server first. That means a copy of your photo, contract or bank statement sits on a computer you know nothing about.
Today's browsers are powerful enough to do this work themselves. So we built tools that do exactly that: they load once, then convert your files right on your own computer or phone.
Our promise
Your files never leave your device.
We do not upload, store or look at your files. We do not use cookies, analytics or advertising trackers. There is no account to create. You can read the details in our privacy policy and check them yourself with the steps on How it works.
How we work
- Private by design. The site has no upload feature at all, and a strict security policy blocks data from being sent to other websites.
- Free and simple. No sign-up, no watermarks, no limits on how often you use a tool.
- Honest. Every listed tool is live and runs on your device. File limits and browser requirements are shown on each tool page.
- For everyone. Plain English, works on phones and computers, and built to be accessible. See our accessibility statement.
Who is behind it
OnDevice Tools is a small, independent project. We build each tool carefully and add new ones over time. If you have an idea for a tool or found a problem, please get in touch.
