Runs in your browser, files stay on your deviceBy choosing a file you agree to our Terms of use and Privacy policy.

Blur face areas in your photos in a few clicks before you post, publish or send them. FileKiwi's AI detects the faces in your picture and covers them with a blur or pixel effect.

Detection runs in your browser, so the original picture is never uploaded. Click a face to include or skip it, and draw your own box over anything else that should stay private, like a license plate, a name badge or a computer screen. Download the result as JPG or PNG.

Why use FileKiwi for this

Finds faces for you

No need to trace every person by hand in a group shot or a crowd.

You stay in control

Keep your own face visible and hide only strangers, or the other way around.

Blur or pixelate

Choose the look you prefer and raise the strength until nobody can be recognized.

Private from start to finish

Detection and blurring happen on your device. The unblurred photo is never uploaded.

When to blur face details before sharing

Not everyone in a photo agreed to be online. Blurring is a simple way to respect that. People often use it for:

  • School and club events, where other people's children appear in the background.
  • Street and travel photos full of passersby.
  • Car and property listings that show license plates, house numbers or neighbors.
  • Screenshots and office photos with names, badges or open screens.
  • Reports and news posts about protests, incidents or sensitive topics.

The draw a box feature covers anything the face detector does not handle, so one tool takes care of faces, text and objects together.

Make sure the blur really hides identity

A face can stay recognizable if the effect is too gentle, especially in a large photo. Compare the two styles:

StyleLookGood for
BlurSoft, blends into the photoSocial posts, news style images
PixelateBlocky, clearly hidden on purposeScreenshots, documents, evidence style photos

Before you download, zoom in and check:

  1. Every face was found. Small, turned away or shadowed faces can be missed, so draw a box over them.
  2. Reflections in mirrors, windows and sunglasses.
  3. Hair, tattoos or clothing that could still identify someone.

Share only the new file and keep the original private. If people in the frame should simply disappear, crop the image instead. To soften a whole scene, use Blur Background.

Tips for group and crowd photos

In a busy picture, the detector may find dozens of faces. Start by deciding who should stay visible, then click those faces to exclude them, rather than adding the rest one by one. For very small faces far in the background, raise the strength a little, because a light effect on a tiny face can still hint at who it is. When a whole area is full of people, a single drawn box over that area is often quicker and safer.

Blur Face: frequently asked questions

How do I blur face details in a photo automatically?

Drop the photo onto the page and the AI marks every face it detects. Choose blur or pixelate, adjust the strength, and download. You can click any face to skip it, for example your own, before you save.

What if a face was not detected?

Faces that are tiny, turned away, in shadow or partly covered can be missed. Check the preview carefully and draw a box over any face the AI skipped. The same box tool works for anything else you want hidden.

Can I blur license plates or text too?

Yes. Draw a box over a license plate, a name tag, a document, a screen or a house number, and FileKiwi hides that area along with the faces. This is useful for car listings, property photos and screenshots.

Is the photo uploaded to a server?

No. Face detection uses the YuNet model inside your browser, and the blurring happens on your device too. Your original, unblurred picture is never sent anywhere.

Should I choose blur or pixelate?

Both hide identity when the strength is high enough. Blur looks softer and blends into the picture. Pixelate shows clearly that something was hidden on purpose. Whichever you choose, zoom in and check the result before you share it.

Can someone undo the blur?

The download is a new image where the hidden area has been replaced by the effect. A very light setting can still leave a face recognizable, though, so use a strong setting for sensitive photos and never share the original.
