Is there an online tool that generates the corresponding LaTeX code of a diagram which can be drawn using a graphical interface? A tool such as latexdraw but only using a web browser (like Detexify)?

    If tikz code counts as "latex code", you can use inkscape to draw svg, and there exists a plugin which saves it as tikz code. For the web browser requisite, you can use svg-edit.googlecode.com/svn/branches/2.5.1/editor/… as editor, but still require inkscape to convert the svg to tikz. – JLDiaz Nov 30 '12 at 10:05

    @Karlo Thanks for the heads up. Apparently github.com/kjellmf/svg2tikz is the new way of doing that. – JLDiaz Jul 19 '17 at 16:00

    github.com/kjellmf/svg2tikz seems no longer under active support now. – Yu Shen May 21 '19 at 19:11

A wonderful option is mathcha: www.mathcha.io

enter image description here

just open the editor, you log in and you make your drawings and equations.

this online program will create different export formats, including Tikz, which is compatible with Latex.

  • Played a bit with it. It seems really solid. Some improvements could still be made (for instance I see no export to PDF/SVG option, and text editing does not respect some keyboard shortcuts), but if it doesn't die I see myself using it in the near future. – levesque May 18 '18 at 15:03
  • Alright, found the PDF/export functions. Never mind that complaint! – levesque May 18 '18 at 15:11
  • Where is the PDF export function? I couldn't locate it anywhere. Besides, I can't export the TikZ code (it exports nothing except some opening and closing tags). – Jim Raynor Jun 13 '18 at 22:23
  • Best tool ever! Thanks! – Jinhua Wang Apr 11 '19 at 20:59
  • I cannot help loving it! – inmybrain Nov 29 '19 at 12:33

The GeoGebra online tool, which can also be installed and run locally, comes to mind. It let's you do geometric drawings: define points, intersections, ellipses given the two foci and a point, etc... It will generate TikZ code for you.

For example, create an ellipse within your browser geogebra online

This can be exported to TikZ (will generate a standalone document), which renders to geogebra tikz

    Note that tikz code exported by GeoGebra is not of highest quality... – mbork Dec 10 '12 at 8:14

    GeoGebra doesn't make any sense. I tried using it and it keeps producing lines even if when I choose circle. – DrB Oct 5 '17 at 4:40
  • The downside seems to be the standalone export. I don't see any option to directly embed the generated TikZ into my own document. – Makan Tayebi Aug 16 '18 at 10:47
  • @MakanTayebi You can easily integrate the file into your own document, see i.e. here. – Viktor Glombik Apr 7 '19 at 19:38

If you're looking for a tool to draw commutative diagrams with tikzcd, there's Yichuan Shen's tikzcd-editor.


TikzEdt is a combined WYSIWYG/text editor designed for editing Tikz code. http://www.tikzedt.org/

    It is a nice tool, but it definitely misses the "Online" part OP asked for. – Clément Oct 5 '17 at 4:44
  • Is there an advantage over the WYSIWYG/text editor overleaf? – Viktor Glombik Apr 7 '19 at 19:40
