BG Remover Online removes video backgrounds and exports real-alpha WebM or ProRes 4444 for overlays and editing. It also turns photos into transparent PNGs. Upload a clip (up to 60 seconds/200 MB), preview the cutout against different backdrops, and download a file with actual transparency—not a checkerboard baked into pixels. New Google sign-ins receive 5 free credits (about 5 seconds of video); original audio is not retained. Fine edges may need review.
