→Frequently asked questions
- What is an image mask?
- A mask is a grayscale image that marks which pixels belong to the subject. White is the subject, black is the background, and grays are soft edges.
- What can I use a mask for?
- Masks are used for compositing, selective edits in other software, inpainting, and preparing training data for AI models.
- Can I invert the mask?
- Yes. Turn on invert mask to make the background white and the subject black.
- What kinds of photos work best?
- Photos with one clear main subject, such as a person, pet, or product, give the cleanest results. The subject is found automatically, so no prompt or selection is needed.
- What file formats can I export?
- You can export as PNG, JPEG, WebP, TIFF, BMP, or HEIC.
- Is this tool free to use?
- Yes — completely free, no account needed. Your images are processed entirely in your browser and never uploaded to a server. Downloads have no watermarks.
