# 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
|
||
|
||
1. **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.
|
||
2. **AI processes it** — Our model detects the formula region, runs OCR, and generates structured LaTeX in under a second.
|
||
3. **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:
|
||
|
||
```latex
|
||
x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
|
||
```
|
||
|
||
An image of an integral:
|
||
|
||
```latex
|
||
\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
