How to use Blur Background
Keep the subject sharp and soften everything behind it — adjust the blur until it looks natural.
- Choose a photo.
- The subject is found on your device.
- Set the blur strength; fix edges with the brush if needed.
- Download JPG or PNG.
Questions
Are my photos uploaded?
No. The photo is decoded, analysed and edited inside your browser. The only download is the model itself, once, from Pevlika; after that it loads from your browser cache.
How does it work without a server?
A compact U²-Net segmentation model (about 4.6 MB) runs on your device with ONNX Runtime WebAssembly, and an edge-aware filter refines the outline at full resolution. The first run downloads about 19 MB once.
