Frequently Asked Questions

What image formats are supported by the Measure tool?
Our tool supports JPEG, PNG, WebP, and GIF formats. You can upload any image in these formats and perform precise measurements with high accuracy.
Are my images uploaded to your servers?
No, absolutely not. All image processing and measurements happen locally in your browser using JavaScript. Your images never leave your device, ensuring complete privacy and security.
How does the calibration system work?
The calibration system allows you to set a reference scale by measuring a known distance in your image. Once calibrated, all measurements are automatically converted to real-world units like centimeters, inches, or millimeters.
What measurement tools are available?
The tool supports four measurement types: Distance (between two points), Area (polygon area), Angle (between three points), and Perimeter (sum of distances around a shape).
Can I export my measurement data?
Yes! You can export all your measurements, calibration data, and metadata in JSON format for further analysis or record-keeping.
How accurate are the measurements?
Measurements are pixel-accurate and can be calibrated to real-world units. The precision can be adjusted from 0 to 4 decimal places depending on your needs.
Can I use different units for measurements?
Yes! The tool supports pixels, millimeters, centimeters, inches, and feet. You can change units at any time and all measurements will be automatically converted.
Is there a limit to the number of measurements I can make?
No, you can make unlimited measurements on a single image. Each measurement is saved and can be individually deleted or exported.
