Blur and Pixelate Image Area
Before sharing a photo, there is often one thing in it you should not share: a child's face, a car number plate, an address on a parcel, a name badge, or a private document on the desk behind you. This free tool hides exactly the area you choose. Draw a rectangle over the sensitive part, and it is covered with a mosaic pixel effect or a smooth blur, while the rest of the photo stays untouched.
You pick the effect and its strength. Pixelate replaces the region with large visible blocks, which is the strongest and clearest way to hide something; blur softens it into a haze, which looks gentler for backgrounds and faces in group photos. You can cover several areas one after another, undo the last one if you misjudged, or reset and start again. An honest caution: use a high strength for anything truly private. A weak blur can sometimes be partly reversed by software, while chunky pixel blocks remove the information for good. Everything runs locally in your browser, which matters for a privacy tool: the unedited photo never leaves your device.
How to use
- Click the file box and choose the photo you want to make safe to share.
- Choose Pixelate for strong hiding or Blur for a softer cover.
- Set the strength: higher means bigger blocks or a heavier blur.
- Drag a rectangle over the face, plate, or text you want to hide, then release.
- Repeat for other areas, use Undo if one went wrong, then click Download Edited Image.
Frequently asked questions
Which is safer, blur or pixelate?
Strong pixelation is safer. Research has shown that light blurring can sometimes be sharpened or guessed by software, especially on text. Large mosaic blocks destroy the detail completely, so nothing can be recovered from the downloaded file.
Can I cover more than one area?
Yes. Each rectangle you draw is applied in turn, so you can hide several faces or details in the same photo. The Undo button removes only the most recent area, and Reset restores the untouched original.
Does the effect change the rest of the photo?
No. Only the rectangles you draw are altered; everything else keeps its original pixels, and the image is saved as a lossless PNG at the same dimensions.
Are my photos uploaded anywhere?
No, which is the point of a privacy tool. The original and edited versions stay in your browser, on your device, from start to finish.
