Shape
Distinguish similar symbols such as a letter, digit, operator, or Greek character.
Convert formula images to Markdown or LaTeX
Formula OCR converts visible mathematical notation into editable LaTeX and Markdown math. It preserves symbols rather than solving the expression, so verify superscripts, subscripts, fraction boundaries, roots, matrices, and ambiguous handwritten marks.

The tool transcribes notation and does not solve it. Check superscripts, subscripts, grouped expressions, matrix boundaries, and similar-looking symbols before reuse.
Transcribe notation without changing its meaning
Mathematical OCR has to distinguish position as well as shape. A small shift can turn an index into an ordinary character or change which terms belong inside a fraction, root, or matrix.
- Compare superscripts, subscripts, accents, and limits at source size.
- Check the opening and closing boundary of every grouped expression.
- Render the final code in your destination editor before relying on it.
Transcribe the expression without pretending to solve it
Use this route for one focused equation or a compact formula block that needs reusable math code. The output is a code draft. Mathematical correctness and the truth of the expression remain separate questions.
Position
Preserve indices, limits, accents, and aligned lines because vertical placement carries meaning.
Grouping
Check which terms belong inside each fraction, radical, bracket, case, or matrix.
Capture the full notation at a readable scale
A tight but complete crop reduces competing text while protecting the strokes that define fractions, radicals, brackets, and multiline alignment.
Crop to the expression
Remove surrounding prose, page numbers, and unrelated diagrams. Keep enough margin to preserve fraction bars, root strokes, matrix brackets, and equation labels.
Protect vertical spacing
Do not flatten a low-resolution image until superscripts and subscripts touch the main line. Their position carries meaning even when the character shape is clear.
Check grouping before symbols
Confirm braces, parentheses, fraction boundaries, radicals, and matrix rows first. A correct symbol inside the wrong group still changes the expression.
Test the destination renderer
Paste the result into the Markdown or LaTeX environment where it will be used. Package support and delimiter rules differ between editors.
Use a fixed order for formula review
Start with the large structure, then move inward. This catches errors that a symbol-by-symbol reading can miss.
- Outline the groupsFractions, roots, brackets, matrices, cases, and aligned lines.
- Verify positionsSuperscripts, subscripts, limits, accents, and equation labels.
- Compare symbolsOperators, Latin and Greek characters, digits, punctuation, and spacing commands.
- Render onceConfirm that the destination editor displays the same expression as the source.
Use formula OCR for reusable notation code
For handwritten sources, start with How Handwriting OCR Works, Fails, and Needs Review.
For capture quality and careful transcription decisions, use the formula capture and recognition accuracy guides.
Best for
Printed equations, textbook notation, presentation formulas, and clean digital captures.
Not designed for
Solving equations, proving correctness, or interpreting diagrams and surrounding scientific prose.
Review first
Subscripts, superscripts, limits, fraction scope, root bars, matrix boundaries, and similar symbols.
Move checked notation into a math-aware editor
Copy LaTeX for a TeX document or use Markdown math in a compatible editor. Keep the source image beside the code until grouping, indices, limits, and symbol choices have been rendered and checked.
Formula transcription questions
Does formula OCR solve the equation?
No. The tool transcribes the notation that is visible. It does not calculate, simplify, prove, or validate the mathematical statement. Read the recognition methodology.
Can it read handwritten mathematics?
Clear separated symbols may produce a useful draft, but connected handwriting and personal notation need close source comparison. Understand handwriting limits.
