Corridor Key vs Pixelcut

Corridor Key is a free browser-based AI green-screen keyer that removes a video background and replaces it with a solid color, still image, or video. It accepts standard MP4 clips and returns re-encoded H.264 MP4 files. The service says its AI preserves details including flyaway hair, fur, glass, eyewear, and sheer fabric. Fast Mode processes an eight-second clip in seconds; Full Mode takes longer for sharper edge detail. No account or installation is required, and the free plan has no daily or monthly usage cap, although each clip can be up to eight seconds. It runs in desktop, tablet, and mobile browsers, with processing on its servers. Uploaded clips are sent to a Hugging Face Space running BiRefNet. Corridor Key says it does not store clips or outputs on its own servers; Hugging Face terms apply while files are there. HTTPS protects transmission. Availability can depend on Space downtime or GPU queues, and quality varies with edges, motion, lighting, and source quality.

Pixelcut is an AI photo and video editor focused on product photography, with tools for background removal, upscaling, image expansion, retouching, product shots, ads, and video. Its web background remover accepts JPG, PNG, and HEIC images up to 50 MB and 6000 × 6000 pixels, and offers free HD downloads without a watermark or sign-up. The editor can upscale images up to 16×, use generative fill for retouching, generate shadows, and batch edit hundreds of files. The background-removal page lists bulk processing for up to 10,000 images in one batch, with ZIP export. The API costs 5 credits per image, shown as $0.05 per image, and accepts PNG or JPEG inputs; outputs include transparent PNG, alpha masks, and ZIP files. Pixelcut is available on Android, iOS, and web, with API access. Its free plan includes limited background removal and upscaling, with exports without a watermark. Pixelcut describes its intended users as sellers, creators, and brands working on product photos, e-commerce catalogs, ads, and social content.
