Blur Part of an Image
Blur only the area you choose, with a rectangle, circle or brush.
Quick answer: Choose a picture, set the effect to blur and drag over the part you want to soften. Everything else stays sharp. Your picture is not uploaded.
⚠ Blur and mosaic can be reversed or read back in some cases. Do not rely on them for passwords, ID or card numbers, addresses or faces you must protect. For anything private, choose Cover (solid black): it cannot be recovered.
How to use it
- Choose a picture or drop it on the box.
- Pick a shape (rectangle, circle or brush) and an effect (mosaic, blur or solid cover). Use the Strength slider for how strong the effect is.
- Drag over the part of the picture you want to change. Repeat for other areas. Undo removes the last one.
- Press Download PNG.
Blur and mosaic can be reversed
Blur and mosaic are not safe for private information. They can be partly or fully reversed in some cases, and a light blur or a small mosaic block may still be readable. Software can sometimes sharpen a blurred picture or guess the hidden characters, and the larger the picture the easier it gets. For passwords, card numbers, ID numbers, addresses, licence plates and faces you must protect, use Cover (solid black). It replaces the pixels completely, so nothing can be recovered. The downloaded PNG contains only the edited picture, with no copy of the original inside. This tool does not detect faces by itself: you draw over the area.
