In their own words
FuzzPuppy Video Background Remover
FuzzPuppy Video Background Remover is a free web tool for removing video backgrounds in a browser. It uses AI removal or green-screen chroma key, then exports transparent WebM or MOV files, or MP4 with a replacement color, image, or video background. Processing happens locally in the browser; Fuzz Puppy says video is not uploaded to its servers for processing. MP4 and MOV inputs can be approximately 600 MB, with shorter, lower-resolution clips described as more reliable on modest GPUs. MODNet is the faster AI model, while BEN2 targets more detailed subjects and requires FP16 WebGPU support. AI removal requires WebGPU; green-screen removal does not. The maker lists current desktop Chrome, Edge, or Safari with WebGPU enabled for AI work. Supported mobile browsers process only the first 15 seconds at up to 720p and 24 fps with MODNet or green-screen removal. No signup or watermark is listed, and transparent MOV can be composited in compatible CapCut, Blender, and other alpha-video editors.
Knockout API
Knockout API provides image and video processing through a browser app and API. Its image tools cover background removal and replacement, batch processing, masking, smart crop, stickers, outlines, shadows, and inpainting; the API also handles upscaling, portrait restoration, colorization, and object removal. Video background removal runs asynchronously, with job polling for progress. The browser Canvas supports layered designs with text and effects, and users can save canvases and cutouts to a free account. Developers can connect through REST, any HTTP client, or official Node, React, Python, and CLI options. The service says it manages GPU processing, endpoint updates, usage records, credentials, teams, and billing. Its privacy policy says uploaded images are processed in GPU worker memory, not retained after the response, and not used to train models. The Free plan is free, with 30 images per month and 60 requests per minute. Pay-as-you-go is $0.02 a month, with metered usage billed monthly; Plus is $10 a month. Paid tiers have no monthly cap and a 600-request-per-minute limit.
