Free online TEX to WEBP converter

Source format

TeX is a plain-text markup language used to describe documents for typesetting. It is widely used by academics, scientists, mathematicians, and technical writers for papers, theses, books, and documents with complex formulas. A .tex file usually contains source text, commands, and structure rather than a finished visual layout. To convert TeX to an image format such as WebP, the document must first be rendered by a TeX engine into a visual page or figure.

Target format

WebP is a modern image format developed by Google. It supports lossy and lossless compression, transparency, and good file size reduction compared with older formats like PNG or JPEG. WebP is commonly used for web graphics, previews, documentation images, and situations where smaller image files are desirable without sacrificing too much quality.

How to perform the conversion

The most reliable way to convert .tex to .webp is to render the TeX document to a PDF or image first, then export that rendered output to WebP. For a single-page document or a figure, this workflow is usually best:

1. Compile the TeX file to PDF using a TeX distribution such as TeX Live or MiKTeX. For example, run pdflatex file.tex or xelatex file.tex depending on the document.
2. Open the resulting PDF in a graphics or document tool that can export images. A practical desktop option is ImageMagick, which can convert rendered pages to WebP.
3. Convert the PDF page to WebP with a command such as magick -density 300 file.pdf[0] file.webp. The [0] selects the first page. Increase or decrease -density to control output resolution.
4. If you need a specific crop or transparent background, adjust the TeX source or use image-processing tools before saving as WebP.

If your TeX content is a standalone figure, another common approach is to compile it to PDF and then use a vector or raster editor to export the page as WebP. In desktop software such as GIMP or Inkscape, you can open the rendered PDF and then use File → Export As or File → Export to save as WebP, if the application supports it.

Notes on quality and limitations

TeX is not an image format, so the conversion is really a rendering process. That means the final WebP quality depends on the chosen font rendering, page size, and resolution. For sharp text and formulas, use a high rendering density such as 300 DPI or higher. If the TeX document has multiple pages, you must decide whether to export only one page or create separate WebP files for each page.

Because WebP is raster-based, it is not ideal for preserving the infinite scalability of TeX output. Fine mathematical notation may become blurry if the resolution is too low. For best results, render at the intended display size or larger, and prefer lossless WebP when text clarity matters more than file size.
