Welcome to

uRlTeX is an online TeX engine, targeted for generating images of equations from the url for simple embedding in a webpage.

This is an equation created with uRlTeX:

To create a png image, request the url urltex.com/png/[equation mode TeX code].

To create a svg image, request the url urltex.com/svg/[equation mode TeX code].

Note that backslash has to be url-encoded as "%5c" which makes the TeX-code a bit annoying to read.

Here is another example creating an svg:

And another one:

Usage

Embedding in a page

<img src="http://urltex.com/png/F(%5comega) = %5Cint_{-%5cinfty}^%5cinfty f(t) e^{-i%5comega t} dt" alt="Fourier transform" />

This will redirect to the image

Generating images for use anywhere

Two formats are suported: png and svg.

Fill in the TeX code for the wanted equation below and press OK to get the image and a properly formatted url for its generation.

For png, the URL to paste in your html is:

And for svg it is:

If you do not know TeX, perhaps this site is not super useful, but I would think it is still the easiest way to get a pretty equation to a website, so might be worth reading up a bit.

Things to do

• Create an interface that can take parameters like size and color
• Send some error image on invalid TeX
• Add capability to scale image (partially solved by svg-creation)
• Manage background color/transparency

There is a discussion on Reddit where you can post comments or wishes.
