Frequently Asked Questions

Does this online gear generator work on Mac, Windows, and Linux?

Yes! Because GearDXF runs natively in any standard modern web browser, it works identically on Windows, macOS, Linux, and Chromebooks.

Are my designs uploaded to an external server?

No. All gear mathematics, geometry calculations, and file exports are computed directly on your local device. Your designs remain completely private.

Can I save my gear designs to come back later?

GearDXF automatically stores your current canvas state in your browser local storage so your work is preserved when you return.
