Blur Photo Background
Blur a whole photo in one tap, then paint the person or object back into focus by hand. Saves a JPG.
How to use
- Choose a photo or drop it in.
- Set the blur strength (2–40 px) and press Blur everything to blur the whole picture.
- The tool switches to the restore brush. Rub over the person or object to bring it back into focus. Use a big brush (8–220 px) for wide areas and a small one at the edges.
- If an edge looks odd, switch to the blur brush and rub over what should be blurrier. Undo steps back through the last 8 strokes; Reset returns to the original.
- Press Download to save a JPG.
FAQ
Does it detect the person and blur only the background?
No. There is no subject detection or background removal. You blur everything first, then paint the part to keep sharp with the restore brush; a small brush along the edge gives the most natural result.
What is the difference between strength and brush size?
Blur strength (2–40 px) is how heavy the blur is; brush size (8–220 px) is the size (radius) of the circle you paint with.
I restored or blurred the wrong part.
Use Undo to step back through up to 8 strokes, or Reset to go back to the original photo.
What happens if I change the blur strength?
The strength is applied when you press Blur everything. Change it and press again, and the photo is re-blurred from the original with the new strength, so anything you restored is blurred again.
What size and format is the saved photo?
A photo whose long side is over 1,600 px is scaled down to 1,600 px for editing and saving. The format is JPG (quality 92%).
Does this change my original file?
No. The result is saved as a new file named background-blur-WIDTHxHEIGHT.jpg and the original stays as it is. The saved file carries no EXIF data such as shooting location.
Does it work on a phone?
Yes, paint with your finger. A bigger brush covers wide areas fast; a smaller one is better for narrow edges such as hair.
Are my settings remembered?
The brush mode, brush size and blur strength are stored in this browser and return next time. Add the photo again after reopening the page.
