→Frequently asked questions
- How do I add a neon outline to a photo?
- Upload your photo. The main subject is detected automatically and traced with a glowing outline in the color you choose.
- Why is the background darker?

- Can I change the glow color?
- Yes. Pick any color for the outline and its glow.
- 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.
