Are you asking for a program with which you can make drawings? If yes, check out Google Drawings.

While there is a web based version,
I like to use the desktop version.
When posting for PF, I’ll take a screenshot of a region. Exporting the view to various formats is also possible, but isn’t 100% reliable.

You can export svg files from geogebra, then edit the svg files in inkscape $-$ https://inkscape.org $-$ then export as png files from inkscape . . .

When submitting figures from GeoGebra for a paper,
I do that: export to svg, clean up in inkspace if needed, then convert to .eps.

For physicsforums (or stackexhange), I just do a screenshot of the region I want... SnagIt gets that into my clipboard. I can directly paste into PF without first creating a png file.

(Exporting .eps isn't reliable. Exporting various TeX-package graphics commands isn't reliable.
... at least in GeoGebra 5 classic. [I prefer it to GeoGebra 6].)
