FAQ

Is this background blur tool free?

Yes. Upload a photo, apply portrait-style background blur, preview the result, and download a PNG with no account or payment.

Are my images uploaded to a server?

No. AI cutout and blur compositing run entirely in your browser. Your files stay on your device.

Can I control how strong the blur is?

Yes. After processing, use the blur intensity slider to fine-tune softness from a light haze to a strong portrait bokeh look.

Which image formats are supported?

Upload JPG, PNG, or WebP files up to 10 MB. Exports are PNG.

Why does the first run take longer?

The AI model downloads once and is cached by your browser. Later blurs are significantly faster.

Can I use the results commercially?

Yes. PNGs you download are yours to use in headshots, marketing, social posts, and personal projects.

Need a new background instead?

Swap in a solid color or custom photo, remove backgrounds entirely, or upscale photos — Focera keeps everyday image utilities in one fast hub.
