Nexa Convert Overview
Nexa Convert is a set of media tools — image conversion, background removal, watermark removal, and audio/video conversion — with one thing in common: everything runs in your browser. No file you process is uploaded to a server.
Tools
| Tool | What it does |
|---|---|
| Convert | Convert images between common formats |
| Background | Cut a subject out from its background using an AI segmentation model |
| Watermark | Paint out a watermark or unwanted object from a photo |
| Audio & Video | Convert audio and video files between formats |
Why local processing matters
Because processing happens on your device, your files never leave your browser tab. This also means very large files or complex operations depend on your device's own performance, not a server's.
First use may take a moment
The Background and Watermark (AI mode) tools use real neural network models that run locally via WebAssembly. The first time you use either, your browser downloads the model (roughly 200MB) and caches it — subsequent uses are fast since the model is already cached.
