Relight AI: Photo Background Changer
Relight AI is a browser-based photo-lighting tool. The official page presents a preset-driven Quick mode and a Prompt mode for describing the desired light. Its examples concern portraits, product shots and consistent lighting across several images. The current presentation centers on relighting, even though an older-looking instruction section also discusses changing backgrounds.
Describe the light you want
Quick mode uses ready-made presets; Prompt mode accepts a written description of lighting. The page recommends describing direction, mood, color and intensity, with examples such as soft studio lighting from the left. Specify those properties around the existing subject rather than relying on a vague request for a professional result.
Uploads accept JPG, PNG or WebP up to 5 MB. The FAQ says clear photos with a visible, sharp subject work best. Choose a representative image that you are authorized to edit, then compare the result with the original before processing an entire set.
Inspect skin tones, shadows, reflective surfaces and the subject's edges. A generated lighting change can alter the appearance of a product or scene, so check factual details if the image will inform a purchase or document an event. These are suggested checks, not results from a photo we uploaded.
Evaluate consistency and the selected mode
The page describes uploading multiple photos and applying one lighting prompt across the batch. That is useful to evaluate for product sets, but a shared prompt does not establish identical output or a complete batch allowance. Check several different poses, backgrounds and exposure levels before relying on consistency.
The how-to section refers to a Background Prompt and changing the photo background, while the current controls and FAQ describe lighting modes. Confirm what the selected interface actually does instead of assuming relighting always includes a full background replacement.
The site's comparison with Clipdrop is its own marketing description, not an independent speed or quality test. Judge the intended edit on your source material rather than using that comparison as evidence of superiority.
Confirm credits and image handling
One section advertises unlimited free generations without signup, but the FAQ instead describes free credits and subscriptions for more features and credits. Those statements do not establish a reliable unlimited allowance. Check the account or credit conditions before planning a batch.
The privacy answer mentions deletion after a limited period without giving a precise retention interval. Review current terms before uploading sensitive photographs. The captured source does not establish export resolution, commercial licensing or independently verified privacy controls.
