What makes these tools different

Your files never leave your device
Images, text and data are processed with JavaScript in your browser tab. You can check it yourself: open your browser's developer tools, switch to the Network tab and run a tool. No upload request appears.
No account, no limits, no watermark
Every tool works the moment the page loads. There is no daily cap, no "pro" tier and nothing added to your output.
The math is shown, not hidden
Calculators show the formula they use next to the result, so you can check the numbers or reuse the method in a spreadsheet.
