Below you will find a large collection of Transformers-inspired typefaces/fonts.
The main Transformers-logo font, SF TransRobotics, was designed by Derek Vogelpohl of ShyFoundry. ShyFoundry has an updated version of the font called "SF Animatron" for sale at their site (for a very reasonable price, if I may say). The remaining fonts are based on other Transformers logos and text which has appeared in Transformers fiction.
Many of these fonts have faction insignia in them, typically in place of either the square brackets or the greater than and less than signs. Some of them have support for extended characters (accented letters, various typographical symbols, punctuation, etc.) and some don't. Similarly, some have bold and italic/oblique versions, and some do not. If in doubt, try it out.
Each font is availabe for an individual download -- just click it's example sentence -- or you can just grab the whole set in one ZIP file. (Revue is not included in the big ZIP, since it's not a TF font.)
Classic Transformers Lettering
By Alden Bates and Iggy Drougge. An extremely old Windows-format ".FON" font file that probably nobody can even use anymore. This font does not scale like a more modern TrueType font. It only comes in one size. So why use it? It's the only font that has the three-dimensional beveled look to it. Note that some of the letter shapes to this font are inaccurate when compared to the real logo; for example the capital A is too narrow. Feel free to use this for fun, but don't put in on officially licensed products, please!
Fonts by Neale Davidson
Based on the word "Transformers" as it appears in the RID, Armada, Energon, and Universe logos. This font is modified from a general-use font called "Revue", so if you like it, try that one as well.
A collection of all the faction insignia from Neale's other fonts. Includes: G1 Decepticon, G2 Decepticon, BW Predacon, BM Vehicon, CR Combatron, Metals Blentron, G1 Autobot, G2 Autobot, BW Maximal, BM Maximal, Dinobot, Mutant, Mini-Con, Playschool, and CR Moon.
Fonts by Jim Sorenson
Based on writing seen on Maximal computers in Beast Wars. All the characters in the font appeared on the show. Additionally, the capital letters and the numbers are show-accurate. That is, those glyphs have been assigned to the same letters that Mainframe used when creating the Maximal computer displays. You can "decode" the text you see in the show, and it often says amusing stuff! (And sometimes it's gibberish...)
Based on writing seen on Predacon computers in Beast Wars. Similar to the Maximal Text font, A-Z and numerals 1-8 are "canonical", as Jim calls it, and can be used to read Predcon writing in the show.
