Blur only what you choose
Sometimes you only need to hide one thing — a face in the corner, a sign in the background, a number on a screen — while keeping the rest of the photo crisp. This tool lets you drag a box over exactly that area and blur, pixelate, or black it out, leaving everything outside the box at full resolution.
Add as many boxes as you like, each obscured independently, and adjust the strength to taste. When you download, only the selected areas are changed and the effect is flattened into the file — so the rest of your image is untouched and the hidden parts can't be recovered.
How to blur part of an image
- Open your image. Drag it onto the tool, choose a file, or paste it.
- Drag over the area. With Selected areas chosen, drag a box over just the part you want to hide. Add more boxes if needed.
- Adjust and download. Set the blur strength (or switch to pixelate/redact), then download in your original format.
Resize by re-drawing
To change an area, remove it with the small ✕ on the box (or Undo) and drag a new one. Draw the box slightly larger than the detail so nothing identifying peeks out at the edges.
Cómo funciona blur part of an image
- Qué hace
- Desenfoque selectivo de una o varias zonas
- Cómo lo hace la herramienta
- Arrastras un recuadro solo sobre el área que quieres ocultar y eliges desenfoque, pixelado o una barra sólida; el efecto se aplica por zona y se recorta a ese recuadro, así que cada píxel fuera de tu selección conserva su resolución original completa.
- Para qué sirve
- La ocultación selectiva es para cuando necesitas tapar solo una cosa —una cara en una esquina, un cartel al fondo, un número en un monitor— sin suavizar ni degradar el resto de la foto.
- ¿Se puede revertir?
- Solo se alteran las zonas recuadradas y el resultado se aplana en el archivo descargado, así que las partes ocultas no pueden recuperarse mientras que las zonas intactas siguen siendo idénticas píxel a píxel al original.
Consejo: Dibuja el recuadro un poco más grande que el detalle para que nada identificativo asome por los bordes; para cambiar el tamaño de un recuadro, elimínalo con su ✕ y dibuja uno nuevo.

Preguntas frecuentes
How do I blur only one part of an image?
Choose Selected areas and drag a single box over the part you want to hide. Everything outside the box stays sharp.
Can I blur several separate parts?
Yes. Drag a box over each part; every box is blurred independently, and you can remove any one of them.
Does the rest of the image stay sharp?
Yes. Only the areas you box are blurred; the rest keeps its full resolution. The effect is baked in when you download.
Where is my image processed?
The blurring happens in your browser, so the new file is created on your own device. How any data associated with the tool is handled is described in our privacy policy.
