How to use Blur background
- Add a photo of a person, pet or object.
- Tap or drag on the picture to put the sharp oval over your subject, and use the width and height sliders to fit it.
- Raise Blur amount until the background looks as soft as you like.
- Use Paint sharp and Paint blur to correct the edges, then download the result.
Why use this tool
A blurred background pulls attention to the subject and hides clutter such as a messy room or passers-by. Phones do this with depth sensing; this tool gives you the same look on any photo, and you stay in control of where the sharp area ends. Your picture is never uploaded.
How it works
The tool makes a blurred copy of your picture and blends it with the original. Where the blend is fully sharp is the focus area you choose, and the Soft edge setting controls how gradually it fades. It does not recognise people or objects automatically, so for subjects with an unusual outline use the brushes to follow the edge.
Tips for best results
- Use a large Soft edge for portraits so the fade looks like a real lens, and a small one for products with clear edges.
- Brush with a small size near hair and fingers, and a large size across empty areas.
- Try Horizontal band for landscapes or a tilt-shift look: a sharp stripe with blur above and below.
- If you want the opposite, choose None, paint sharp over your subject and let everything else stay blurred.
Frequently asked questions
Is my photo uploaded?
No. The blur is calculated in your browser and the picture stays on your device.
Does it find my subject automatically?
No. You choose the sharp area and fine-tune it with the brushes. This keeps the tool fast and private, and it works on any kind of picture.
Is the picture made smaller?
Photos larger than 2400 px on the longest side are scaled down so the tool stays quick on phones. Smaller pictures keep their full size.
Why do I see a dashed outline?
It shows where the focus area is while you move it. It is not part of the saved picture.
