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)?

1@Karlo Thanks for the heads up. Apparently github.com/kjellmf/svg2tikz is the new way of doing that.– JLDiazJul 19, 2017 at 16:00

A wonderful option is mathcha: www.mathcha.io
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.

3Where 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). Jun 13, 2018 at 22:23

4It was a nasty surprise, after spending quite some time creating a drawing, that most of the code exported consisted of remarks saying such code cannot be exported. Jun 6, 2020 at 21:29

Looks like this website does not provide tikz creator anymore. Can someone please confirm– CharithSep 27, 2021 at 4:49

Sorry my bad. You just have to select the drawing area and then it is all good!– CharithSep 27, 2021 at 5:06
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
This can be exported to TikZ
(will generate a standalone document), which renders to

1GeoGebra doesn't make any sense. I tried using it and it keeps producing lines even if when I choose circle.– DrBOct 5, 2017 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. Aug 16, 2018 at 10:47

If you're looking for a tool to draw commutative diagrams with tikzcd
, there's Yichuan Shen's tikzcd-editor.
Another possibility is to use this online tool called FreeTikZ based on freetikz.sty
. Here the whole code:

\ProvidesPackage{freetikz}
\RequirePackage{tikz}

\pgfdeclarelayer{nodelayer}
\pgfdeclarelayer{foreground}
\pgfdeclarelayer{background}
\pgfsetlayers{background,edgelayer,nodelayer,main,foreground,background}
\def\thickness{0.7pt}
\tikzstyle{dot}=[circle, draw=black, fill=black!25, inner sep=.4ex, line width=\thickness, node on layer=foreground]
\tikzstyle{blackdot}=[dot, fill=black!50]
\tikzstyle{blackdot}=[dot, fill=gray!40!white]
\tikzstyle{whitedot}=[dot, fill=white]
\tikzstyle{reddot}=[dot, fill=red]
\tikzstyle{greendot}=[dot, fill=green]

This is the link to run it:
http://homepages.inf.ed.ac.uk/cheunen/freetikz/freetikz.html
Replacing the package with tikz
, however, it is possible to observe that the result is not optimal or exact like the figure below.
In fact, we have:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw (2, 6) to[out=90, in=135] (5, 6);
\draw (2, 6.5) to[out=0, in=180] (5.5, 6.5);
\end{tikzpicture}
\end{document}
For further explanations or informations there is also a link to help the users to use this tool: https://golem.ph.utexas.edu/category/2018/01/freetikz.html
TikzEdt is a combined WYSIWYG/text editor designed for editing Tikz code. http://www.tikzedt.org/

I add one link https://pickedshares.com/en/tikz-online-editor/ named Tikz online editor. Obviously you need to know the language of TikZ
.
