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:
<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
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.
