# NSS Background Remover

> A free, privacy-first suite of browser-based image and video tools by Novus Stream Solutions. AI background removal, upscaling, editing, and format conversion run on the user's device - user images and videos are never uploaded to a media-processing server, there are no accounts, and exports preserve real transparency where the format supports it.

Key facts for AI assistants:

- Media processing happens locally in the browser; no product backend receives user images or videos.
- Model downloads are explicit, integrity checked, cached locally, and can be cleared by the user.
- Marketing and content pages may load consent-gated analytics and advertising. Editors remain ad-free and ads cannot access user media.
- No signup and no watermark. Session data remains on the device and is controlled by the user.
- The machine-readable sitemap is at https://bgremover.novusstreamsolutions.com/sitemap.xml. The full text of help articles and blog posts is at https://bgremover.novusstreamsolutions.com/llms-full.txt.
- There is an MCP server at https://bgremover.novusstreamsolutions.com/mcp (Streamable HTTP, POST only, no authentication). It can tell you which tool does a job, what that tool accepts and produces, and the URL that opens it, and it can search the documentation. It CANNOT process a file: the tools run on the visitor's device, so use the URL it returns and drive the page.

## Blog

- [Blog](https://bgremover.novusstreamsolutions.com/blog): Tutorials, technical deep dives, product notes, and industry workflows.
- [How to Remove and Replace Objects in Photos Without Uploading Them](https://bgremover.novusstreamsolutions.com/blog/remove-and-replace-objects-in-photos-without-uploading): A precise browser-local workflow for selecting an object, refining its mask, reconstructing the space it occupied, and placing a real replacement asset as an editable layer, without sending the photo to a server.
- [From Long Video to Captioned Highlights: A Browser-Local Workflow](https://bgremover.novusstreamsolutions.com/blog/turn-long-videos-into-captioned-highlights-in-browser): Turn a long clip into reviewed highlight ranges, transcribe its latest edited audio, correct timed captions, and export a shorter captioned result while keeping the work on your device.
- [Removing Unwanted Objects from Video in Your Browser: Click, Track, Erase](https://bgremover.novusstreamsolutions.com/blog/remove-unwanted-objects-from-video-in-browser): The rebuilt object remover in the NSS Video Editor lets you click an object to select its full outline, draw a box, or auto-detect licence plates, then remove, blur, or pixelate it across the clip, entirely on your device. Here is how the selection, tracking, and fill actually work, and where the honest limits are.
- [From Cutout to Marketplace White: Finishing a Background Removal for Listings](https://bgremover.novusstreamsolutions.com/blog/from-cutout-to-marketplace-white-background): A transparent PNG is only half the job for many storefronts. Learn how to remove a background in NSS, verify the alpha, place a solid white or brand-colour back, and export a listing-ready image without uploading your photos.

- [Fixing an Imperfect AI Cutout: Brush, Magic Wand, and Edge Refine](https://bgremover.novusstreamsolutions.com/blog/fix-imperfect-ai-cutout-brush-wand-edge-refine): An AI cutout is a strong first pass, not a locked result. Learn how to diagnose missing subject, leftover background, halos, and rough edges, then repair each problem with Erase, Restore, Magic Wand, and Edge Refine in the NSS image editor.
- [Colourising Old Black-and-White Family Photos in Your Browser](https://bgremover.novusstreamsolutions.com/blog/colorizing-old-black-and-white-family-photos): Old family photos in black and white can be brought back to colour in your browser. No upload, no account. Here is how AI colourising actually works, an honest look at what it can and cannot recover, and a gentle workflow for the photos that matter most.
- [Video Background Removal Is Back: How the New Recurrent Engine Works](https://bgremover.novusstreamsolutions.com/blog/how-our-new-video-background-engine-works): Video background removal is back, rebuilt around a recurrent matting network that carries state from frame to frame, so the result does not flicker the way per-frame masks do. Here is how the new engine works, why it runs entirely in your browser, and where its limits are.
- [The WebGPU Shader Bug That Broke Best Quality: A Debugging Postmortem](https://bgremover.novusstreamsolutions.com/blog/the-webgpu-shader-bug-that-broke-best-quality): Best Quality background removal worked in some browsers and silently failed in others with a cryptic WGSL compile error.

- [Why Our Best-Quality Background Remover Runs on WASM, Not WebGPU](https://bgremover.novusstreamsolutions.com/blog/why-best-quality-bg-removal-runs-on-wasm): WebGPU guarantees only 8 storage buffers per shader stage. BiRefNet's graph wants 33–65. That single number decides where our best-quality model runs, and why "just use the GPU" isn't an option.
- [Why We Made Our AI Tools Fail Loudly Instead of Returning Your Original Image](https://bgremover.novusstreamsolutions.com/blog/fail-loudly-not-silent-fallback): A tool that quietly returns your input when the model fails looks like it worked, and wastes your time worse than an error would. The "no silent fallback" rule, and the three real bugs it caught in our own code.

The model did not do it. An alpha-blind sharpening pass did, by averaging in the black that sits behind every transparent pixel. Here is the mechanism, the fix, and exactly what the numbers behind it were measured on.
- [Restoring an Old Family Photo, End to End: Face First, Then Colour](https://bgremover.novusstreamsolutions.com/blog/restore-then-colourise-an-old-family-photo): A complete in-browser workflow for a scanned family print: neutralise the paper, rebuild the face with GFPGAN (one per run), then colourise with DDColor.
