Instructions

Software Usage Instructions

Enter a LaTeX formula: Enter or paste a LaTeX math formula in the code input box, and the page will automatically generate a preview on the right. You can also click “Load Example” to quickly view the formula effect.
Insert symbols and templates:
- Common symbols: Supports fractions, radicals, superscripts and subscripts, summations, integrals, limits, Greek letters, relation symbols, arrows, and more.
- Structure templates: Supports structures such as matrices, piecewise functions, multi-line alignment, vectors, partial derivatives, and chemical formulas.
Set export parameters:
- Formula mode: You can choose display formula or inline formula.
- Image parameters: You can set formula scaling, PNG scale, image margins, background color, and formula color.
- File parameters: You can set the export file name and copy code format.
Check the live preview: After confirming that the preview area displays correctly, proceed to download or share. The status bar will show the character count, command count, bracket check, and rendering status.
Download or copy the result: You can download a PNG image, SVG vector graphic, or TeX source code, and you can also copy the LaTeX code, SVG source code, or share link.
Save settings: Frequently used export parameters can be saved by clicking “Save Settings”, so the same parameters will continue to be used the next time you open the tool.

FAQ

A: First check whether the brackets are paired, whether any backslashes are missing, and whether command names are spelled correctly. You can also use the symbol panel or an example formula to replace the handwritten part, then modify it step by step.

A: PNG is suitable for direct insertion scenarios such as courseware, question images, and document illustrations; SVG is suitable for scenarios that require scaling, further editing, or embedding in web pages; TeX is suitable for saving formula source code.

A: Go to “Export Settings,” set the background color to “Transparent,” then go to “Download & Share” to download a PNG or SVG. A transparent background is suitable for overlaying onto documents and courseware with different colors.

A: In the “Structure Templates” area, click “Matrix” or “Piecewise Function.” The tool will insert the corresponding LaTeX structure at the cursor position, then you can replace the variables and conditions as needed.

A: You can copy plain LaTeX code, or copy it wrapped in dollar signs or square brackets. Plain code is suitable for further editing, while wrapped formats are suitable for text environments that support math formulas.

A: Dark-colored formulas are recommended for light backgrounds, and light-colored formulas are recommended for dark backgrounds. The tool provides quick options such as transparent, white background with black text, light gray background, and dark background with white text.

A: The share link includes the current formula content, so the formula input can be restored after opening it. Export settings such as color, margins, and file name can still be adjusted on the page as needed.
