Reporting a rendering problem

If a stereogram renders incorrectly — blank areas, visible seams, or an image that never fuses — please include:

  • your browser and version (e.g. Chrome 126, Safari 17),
  • your device and operating system,
  • the settings you used: subject, pattern, and depth value.

Because generation is fully client-side, we never see your inputs — these details are the only way we can reproduce an issue.

Usage and licensing questions

Stereograms you generate are free for personal and non-commercial use. If you'd like to use them commercially — in a product, publication, or campaign — email us with a short description and we'll sort it out quickly.

Before you write

Two pages answer the majority of messages we receive: the viewing guide (for "I can't see the image") and the FAQ (for everything else, from eye safety to phone viewing). If they don't cover it, we're happy to help directly.
