Free lifetime license

Registration

Complete a free registration to receive a license key. There is no purchase, plan, or donation required to use it.

Why a license exists

Open access was abused by automated traffic and abusive load. The license protects the servers and helps keep DithX reliable and affordable. It is not a paid subscription.

How long it lasts

The license is free and intended for life.

If you see 2050, that is a technical reference date, not an expiry you need to pay to renew.

What you can do with DithX

Dithering

Dithering converts grayscale values into patterns a laser can burn as lighter and darker tones. The method you choose changes detail, contrast, and texture.

Who it is for

Beginners use it to learn, while shops rely on it for real projects without an extra mandatory software subscription.

What DithX does not decide

Laser, material, lens, focus, power, speed, and resolution still define the final result. DithX only prepares the image for the right machine workflow.

For legal boundaries and conditions, see the current DithX terms.

Your images

No permanent archive

DithX does not store your photos as a permanent gallery or archive.

About 5 minutes

An upload stays on the server only while processing runs. After about 5 minutes, the file and temporary data are removed automatically.

That short window exists for the output itself, not to keep a copy of your work.
