NSS Background Remover Platform is a free browser suite for removing backgrounds, editing images and video, and upscaling images. Image removal accepts PNG, JPG, WebP, AVIF, and HEIC files, handles batches of up to 100 images, and exports straight-alpha transparency. Video removal can isolate people or process other subjects frame by frame, producing transparent WebM or composited MP4 while keeping audio. Image tools include erase and restore brushes, a magic wand, edge refinement, background replacement, layers, and 3D mode. Video tools include scenes, object removal, grading, text overlays, layers, trimming, and export. The platform lists 40 free tools, 32 cinematic presets, four alpha-capable formats, and 66 help articles. Processing occurs inside the browser; NSS says files stay on the device and are not sent to its servers. No account, quota, watermark, or installation is required. Supported browsers include current listed versions of Chrome, Edge, Opera, Firefox, Safari, and iOS Safari. Limits include a 4096-pixel working side, 100 MB images, 500 MB videos, and duration caps.
