Free online TEX to PNG converter

Source format: TeX

TeX is a typesetting markup language created by Donald Knuth for producing high-quality mathematical and technical documents. A .tex file is usually plain text containing commands for structure, equations, fonts, and formatting rather than final visual output. TeX is widely used for papers, books, lecture notes, and formula-heavy snippets.

In many workflows, TeX is compiled into a PDF or DVI file before it is viewed, printed, or converted into an image.

Target format: PNG

PNG is a raster image format with lossless compression and broad compatibility. It supports transparency and sharp rendering of text and graphics, which makes it useful for screenshots, diagrams, web graphics, and formula images. Unlike vector formats, PNG does not scale infinitely without losing quality.

For TeX content, PNG is often used when you need a rendered image of an equation, symbol, or short TeX fragment for slides, websites, or documentation.

How to convert TeX to PNG

The best method depends on whether your TeX file is a full document or just a formula snippet. In most cases, the most reliable workflow is to compile TeX to PDF first, then convert the PDF page or cropped output to PNG.

Option 1: Use the built-in converter on 101convert.com

1. Open the TeX to PNG conversion page on 101convert.com.
2. Upload your .tex file.
3. Start the conversion.
4. Download the generated .png image.

This is the simplest way to convert online for free without installing software.

Option 2: Convert locally with TeX tools and image software

1. Compile the TeX source with a TeX distribution such as TeX Live or MiKTeX. For example, run pdflatex file.tex to produce file.pdf.
2. Convert the PDF to PNG using an image tool such as ImageMagick. A common command is magick -density 300 file.pdf file.png.
3. If you only need the equation area or a small portion of the page, crop the image afterward with an editor such as GIMP or use command-line cropping options.

Option 3: Use a TeX editor with export features

Some editors and LaTeX front ends can render a TeX snippet directly and export it as an image. In such tools, look for menu paths like File → Export or Tools → Convert to image. This is convenient for equations and short fragments.

Quality and compatibility tips

• Use a higher render density, such as 300 DPI or more, for crisp text and math.
• Crop the output if you only need a formula or a small section of the page.
• Use a standalone TeX document for equations or snippets so the output stays minimal.
• Check fonts and packages during compilation, because missing dependencies can change the result or cause errors.
• Remember that PNG is raster-based, so it is best for fixed-size images, not scalable editable output.

When PNG is the right choice

PNG is practical when you want to place TeX content on the web, in slides, or in documents that need a ready-to-use image. If you need infinite scaling or editable text, keep the output in PDF or use a vector format instead.
