Frequently Asked Questions
Common questions about formula image recognition, free access, and privacy.
What image formats are supported?
+
The tool supports PNG, JPG, JPEG, and WebP formats. For optimal recognition: ensure resolution is at least 384×384 pixels, minimize unnecessary margins around the formula, and avoid images with extreme aspect ratios.
How accurate is the LaTeX recognition?
+
Accuracy depends on image quality. Clear, high-contrast images with standard mathematical notation typically achieve high accuracy. Handwritten formulas may require some manual editing after recognition.
Can I recognize handwritten formulas?
+
Yes, but handwritten formulas may have lower accuracy than printed ones. For best results, ensure the handwriting is clear and the image has good lighting and contrast.
What types of math expressions can be recognized?
+
The tool can recognize a wide range of mathematical expressions including fractions, integrals, summations, matrices, Greek letters, trigonometric functions, and complex equations.
Can I edit the recognized LaTeX?
+
Yes! After recognition, the LaTeX appears in an editable text area. You can modify it directly before copying or using it in your documents.
What copy formats are available?
+
You can copy the recognized formula in multiple formats: raw LaTeX, Typst, ASCII Math, and MathML. Choose the format that best suits your target application.
Is my image data sent to external servers?
+
Recognition runs entirely in your browser. No images or formula data are uploaded to external servers, ensuring your privacy.
How can I use the recognized formula with the derivative calculator?
+
After recognition, you can copy the LaTeX and use it in LaTeX-compatible applications. The formula can also be used as input for our derivative calculator on the main page.
