Blur Part of an Image

Hide just one area — drag a box over the part to blur and leave everything else sharp, free and in your browser.

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

  1. Open your image. Drag it onto the tool, choose a file, or paste it.
  2. Drag over the area. With Selected areas chosen, drag a box over just the part you want to hide. Add more boxes if needed.
  3. 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.

Comment fonctionne blur part of an image

Ce que ça fait
Flou sélectif d'une ou plusieurs zones
Comment l'outil procède
Vous tracez un cadre uniquement sur la zone à masquer et choisissez le flou, la pixellisation ou une barre pleine ; l'effet est appliqué par zone et borné à ce cadre, de sorte que chaque pixel hors de votre sélection conserve sa pleine résolution d'origine.
À quoi ça sert
Le masquage sélectif sert quand vous devez cacher une seule chose — un visage dans un coin, un panneau en arrière-plan, un numéro sur un écran — sans adoucir ni dégrader le reste de la photo.
Est-ce réversible ?
Seules les zones encadrées sont modifiées et le résultat est aplati dans le fichier téléchargé, donc les parties masquées ne peuvent pas être récupérées tandis que les zones intactes restent identiques pixel par pixel à l'original.

Conseil : Tracez le cadre un peu plus grand que le détail pour que rien d'identifiant ne dépasse aux bords ; pour redimensionner un cadre, supprimez-le avec son ✕ et tracez-en un nouveau.

Questions fréquentes

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.
