ASCII RUNNER README

Art and camera processing happens locally in this browser. The website uses Firebase Hosting for delivery and optional Google Analytics only after permission and adult eligibility. No images, camera frames, or art text are sent to Analytics. Read the current product terms before continuing.

FILES ALLOWED

  • PNG, JPG, and JPEG only
  • 10 MB maximum file size
  • 24 megapixels maximum
  • 8,192 pixels maximum per side

CHECKS BEFORE DECODING

  • Filename extension when available
  • Browser MIME declaration
  • PNG/JPEG binary signatures and structure
  • Embedded width and height
  • Decoder result must match the inspected file

IMPORTANT: Failed files are blocked before rendering. These checks reduce risk but are not antivirus software. Only open images you trust and keep your browser updated.

Age 13+ required. Ages 13–17 need guardian permission. Camera and analytics are adults-only. Do not provide a birth date or identity document.

Leave the app

Only process content you have rights and permission to use. Do not capture bystanders, private documents, or children. Exports can lose detail or contain errors; review them and back up your work. The tool is provided as-is to the extent allowed by law; mandatory consumer rights remain unaffected.
