Which files and devices work best with BOARD

BOARD runs in the browser, so most people can start from a laptop or phone immediately. The main things to know are file type support, the current upload size cap, and how HEIC photos are handled.

This page covers the practical constraints that most often decide whether a first test goes smoothly. BOARD commonly accepts JPG, PNG, WebP, and HEIC uploads, the current upload UI targets files up to 10MB, and HEIC or HEIF images are converted in the browser before upload. If that conversion fails, the fastest fix is usually exporting a JPG or PNG copy from Photos and retrying. The product works on modern desktop and mobile browsers, so the real question is usually file quality and format rather than device type.

Best file choices for predictable removals

  • Use a sharp, well-lit photo where the unwanted object is clearly separated from the background.
  • PNG and JPG are the easiest starting formats.
  • If a phone photo is in HEIC, BOARD can usually convert it automatically before upload.

Mobile tips

  • Use the original image from your camera roll instead of a heavily recompressed screenshot when possible.
  • If the browser feels slow on a very large image, crop closer to the problem area and retry.
  • Long-press the final export if your mobile browser handles downloads differently.
HEIC conversion issues are usually fixable.

If BOARD cannot convert a HEIC file in-browser, export that photo to JPG or PNG from your Photos app first, then upload the converted copy. That is usually the fastest recovery path.
