Terms of use
A few practical ground rules.
Using the tools
The current tools are free to use without a Toolnest account. You are responsible for checking that outputs are appropriate for your task. Keep original files before applying image transformations or text conversions.
Accuracy and limitations
Calculations follow the formulas described on each page. Browser rounding, image codec behavior and institutional policies may affect how a result should be interpreted. The tools are provided as available without a promise that every use case or browser will be supported.
Acceptable use
Use the tools only with content you are entitled to process. Do not attempt to disrupt the service, bypass hosting access controls or use the site unlawfully.
