Turn an equation into a reusable image
A formula pasted as ordinary text can lose fractions, roots and superscripts when you move it between apps. This renderer turns supported LaTeX math into an equation image you can place in notes, slides, worksheets or a website. Enter the math expression, generate a preview and download either SVG or PNG. SVG preserves vector paths for scaling; PNG gives you a familiar raster image. The math engine is bundled with this tool, and the equation is processed locally rather than sent to a rendering API. The output is a visual representation, not a proof that the equation is correct.
Enter math rather than a full document
Paste a mathematical expression without dollar-sign delimiters. For example, use \frac{a}{b}, x^{2}, x_{i} or \sqrt{x}. Group the numerator and denominator with braces, and use braces around multi-character subscripts or exponents. Do not paste a complete LaTeX document containing documentclass, packages or a document environment. This is an equation renderer, not a document compiler. If input copied from a paper includes surrounding $ or $$ characters, remove those delimiters first. Keep the expression under 3,000 characters. Try the supplied quadratic-formula example to check that the engine loads before building a more involved expression.
Generate and choose an export
Select Generate and inspect the white preview area. Both downloads become available after successful rendering and PNG conversion. The SVG uses black ink and vector glyph paths, making it useful when a publishing tool supports SVG import. The PNG uses the chosen white or transparent background. Transparent output works best on a light surface because the equation ink remains black. PNG scale can be set from 1 to 6. A larger scale increases the pixel dimensions while keeping the same equation layout. The status message states the actual PNG width and height so you can judge whether it suits your intended slide or print size.
Understand resolution and SVG sizing
The base image height is 120 pixels, with width calculated from the rendered equation aspect ratio. PNG scale multiplies those dimensions. It does not add mathematical detail or change the expression. Vector SVG can be resized without the same pixel-boundary limitation, although the importing app must support SVG correctly. Very wide expressions are rejected above the base-width limit of 4,000 pixels, and PNG output is limited to 16 million pixels. These limits help prevent browser memory problems. For a long derivation, split the expression into shorter lines or create separate equation images and arrange them in your document.
Fix errors and check mathematical meaning
If the tool reports invalid or unsupported LaTeX, check paired braces and the spelling of commands. An error should clear old output so that you do not accidentally download an earlier equation. If a command depends on an extra package, rewrite the expression using supported math commands or use a full LaTeX environment elsewhere. Custom macros, links, HTML injection and file-loading commands are intentionally disabled. The renderer does not simplify algebra, solve an equation or verify a theorem. Compare each sign, exponent, bracket and fraction against your intended formula. A beautifully rendered typo is still a typo.
Privacy and practical uses
No external equation-rendering API receives your input. The surrounding site can still load normal resources. Output download links are temporary browser object URLs; regenerating, editing or clearing the result removes the old links. Download the image before moving away from the page. For teaching, keep the source LaTeX in your notes so you can edit the formula later. For accessibility, add an understandable text description when you insert the image into a document or webpage. Screen readers cannot recover every mathematical relationship from an ordinary PNG. Include the source expression or a readable explanation alongside the visual when it matters.
FAQ
Does this compile a complete LaTeX document?
No. It renders supported math expressions. Full documents, package loading and arbitrary file access are outside the tool.
Should I include $ or $$?
No. Enter only the mathematical expression. The renderer already uses display-math mode.
Which file is best for scaling?
SVG stores vector paths and is usually the better choice when the receiving app supports it. PNG is more widely accepted.
Can I export transparent PNG?
Yes. Choose Transparent. The equation remains black, so place it on a light background for readable contrast.
Why is a custom command blocked?
Macros, HTML, links and file-loading commands are restricted to keep the local renderer focused and predictable.
Does it check my formula?
It checks whether supported LaTeX can render, not whether the mathematics is true. Review the expression yourself.
Advice
Before submitting or sharing the result, compare it with your original input and the requirements of your project. Keep the source text or declared assumptions so another person can review the output. A generated file is useful only when its content and format match the job you need it to do.
