Creation of new mathURLs is temporarily disabled

February 16, 2019

Unfortunately, and perhaps unsurprisingly after running for over 10 years, our backend finally broke in a way that’s not easy to fix. Many apologies to those of you who rely on this site to create new content — I hope to have things upgraded as quickly as possible but my available time is limited.

Existing mathURLs will continue to function.

still TeX’ing

March 15, 2012

Just want to let all of you know we’re still alive and well, and in fact receiving multiple thousands of visits each month (and that’s not counting embedded PNGs). 

mathURL is a pretty simple service with a limited set of goals, so it’s been pretty quiet on the update front — I really can’t think of anything that needs updating within the parameters of our mission. Any suggestions? Let me know.

Otherwise, keep TeX’ing!

While running mathURL is not expensive, hosting does cost a few dollars per month. So I’ve added some Amazon links — treat yourself to a LaTeX book, and help support this site!

upgrades and tweaks

January 22, 2010

I’ve made some backend upgrades and some tweaks to the interface. The most important thing to note is that we are now less forgiving about typesetting paragraph text in math mode and math in paragraph mode.Make sure you have the right “format as” setting! (This is the drop-down menu next to the “make mathURL” button.)

If you have a single equation, the default “format as:” setting of “equation” is appropriate, but if you’re typesetting multiple equations mixed with text, you’ll want to change that to “paragraph”.

hi Twitter

July 29, 2009

Looks like some new visitors coming this way thanks to AskAPhD on Twitter. Welcome to mathURL!

I like to think the site is pretty user friendly, but if you’re interested in learning more, check out the help page, or leave a comment or question here.

Welcome again!

now even shorter

June 14, 2009

As of today, the question mark has been removed from mathURLs, so they look like instead of

Even better is this: instead of!

Of course, old-style mathURLs will continue to work.

Leave a note here if you notice any bugs.

Now featuring color buttons under the “formatting” tab!


February 26, 2009

Introducing new and shiny features, like automatic previewing and clicky buttons for input!

Unfortunately these changes have upped our browser requirements–mathURL now needs JavaScript. I’ve tested on Firefox 2, Firefox 3, and Safari 3, and I believe it should work on Internet Explorer 7+. Please leave a comment here if you run into any problems.

As always, comments and suggestions welcome.


September 20, 2008

As of tonight, mathurl has some new features:

  1. Explicit mode selction. Choose whether your LaTeX should be interpreted in math mode, inline math mode, or text mode.
  2. Faster previewing. On browsers supporting JavaScript, preview images are loaded faster, without having to reload the entire page.
  3. Access keys. The “preview” and “make mathurl” buttons are access key enabled. Hit Ctrl+P (on a Mac) or Alt+P (on Windows) to activate the preview button, and likewise with M to make a mathurl.

Enjoy! (And please report any bugs you may encounter…)

two ways to make different sizes

August 26, 2008

Is mathURL showing up too big or too small for you? There’s two ways to change the size of your math. Click each equation to see the LaTeX source.

LaTeX size commands

The most obvious way to get your math in different sizes is to use the built-in LaTeX size commands.










Rendering resolution

However, since mathURL must rasterize the output of LaTeX, you can also specify the resolution you want this to occur at, using the \dpi psuedo-command.




The difference

Due to the magic of METAFONT, the Computer Modern TeX font changes shape subtly at different sizes, to make them easier to read: small fonts are proportionally wider and have heavier strokes, while large fonts have thinner strokes. For instance, compare these two examples:



The first is a genuine small font as produced by METAFONT, whereas the second is the normal-size Computer Modern font, optically shrunk smaller.

Which to use? If you’re simply embedding equations in text, use the appropriate LaTeX command to go with your text size. On the other hand, if you’re generating high-resolution images to embed in your presentation, use the \dpi command. (And just say no to Microsoft Equation Editor. Blech!)
