Image to LaTeX
TexPixel's core feature is converting formula images — from photos, scans, or screenshots — directly into LaTeX code you can paste anywhere.
How It Works
- Upload your image — Drag and drop a JPG or PNG into the upload zone, or click to browse. You can also paste from your clipboard.
- AI processes it — Our model detects the formula region, runs OCR, and generates structured LaTeX in under a second.
- Copy the result — Click the copy button next to the LaTeX output. Paste directly into Overleaf, VS Code, Word, or any LaTeX editor.
Input Requirements
| Requirement | Details |
|---|---|
| File formats | JPG, PNG |
| Max file size | 10 MB |
| Recommended DPI | 150 DPI or higher |
| Background | White or light backgrounds work best |
What Gets Recognized
TexPixel handles a wide range of mathematical content:
- Algebra — equations, inequalities, polynomials
- Calculus — derivatives, integrals, limits
- Matrices — 2×2 up to large arrays
- Greek letters — α, β, γ, Σ, Π, and more
- Subscripts and superscripts —
x_i^2,a_{n+1} - Fractions —
\frac{a}{b}, nested fractions - Square roots and radicals —
\sqrt{x},\sqrt[n]{x}
Example
Uploading an image of the quadratic formula gives you:
x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
An image of an integral:
\int_0^\infty e^{-x^2}\, dx = \frac{\sqrt{\pi}}{2}
Tips for Best Results
- Use clear images — avoid blur, shadows, or low contrast
- Crop tightly — the less background, the better the focus
- Dark ink on white paper — ideal for handwritten formulas
- Avoid rotated images — keep the formula horizontal
- One formula per image — for complex multi-part work, crop each formula separately
Limitations
- Extremely faint or pencil-written formulas may have lower accuracy
- Hand-drawn arrows or annotation marks outside the formula may be ignored
- Very large matrices (10×10+) may have reduced accuracy
Copy Options
After recognition, you can copy output in multiple formats:
- LaTeX — raw LaTeX string
- MathML — for web embedding
- Markdown —
$...$inline or$$...$$block - Plain text — Unicode approximation
