Online Photo Blur Tool – Fast, Free and Private
Sometimes you want to share a picture, but not everything inside it. This page explains how to blur a photo online to hide faces, blur the background of a photo or censor sensitive information such as email addresses, license plates and ID numbers.
To actually blur your picture, you can use our secure in-browser editor:
The blur editor runs locally in your browser – your images stay on your device and are not uploaded to our server.
How to Blur a Photo Online (Step-by-Step)
- Open the Secure ID Redactor blur tool in your browser.
- Click “Drop or click to upload image” and choose the photo you want to blur.
- Select the blur mode you want to use: Blur, Pixelate or Blackout.
- Adjust the brush size and intensity until the effect looks strong enough.
- Paint over the part of the photo you want to hide – faces, background, text, logos, etc.
- Use Undo or the Eraser mode if you make a mistake.
- Download your edited photo as PNG, JPG or WebP.
The same tool can work as a photo blur editor, blur background app or blur faces in photos depending on how you use the brush.
What Can You Blur in a Photo?
A flexible online blur tool is useful in many situations. You can quickly:
- Blur faces in group photos or street pictures for privacy.
- Blur the background of a photo to hide your home, office or location.
- Blur text like email addresses, phone numbers or chat screenshots.
- Blur license plates when posting car or traffic pictures online.
- Blur confidential data on passports, ID cards and travel documents.
If you mainly want to blur the background, you can visit the dedicated blur background photo page. If you only need to hide faces, check out the blur face in photo guide.
Why Blur Photos Before Posting or Sending?
Once a picture is shared online, it can be saved, forwarded, downloaded and sometimes indexed or scanned by automatic systems. Blurring sensitive areas helps you:
- Protect your identity and the identity of friends and family.
- Hide children’s faces or school logos in shared images.
- Keep your address, car plate and neighborhood private.
- Avoid leaking confidential work information in screenshots.
- Share proof of documents without exposing every detail.
A simple blur can make the difference between “too much information” and “just enough information”.
FAQ – Blur Photo Online
Is the blur photo tool really free?
Yes. Our blur editor is free for personal use. You can open the page, blur your photos and download them without registration. We may show ads to support development and hosting.
Does it work on iPhone and Android?
Yes. The blur tool runs inside mobile browsers such as Safari or Chrome. Open passport-blur.html, upload a picture from your camera roll and start painting blur directly on your phone.
Can I blur only one part of the photo?
Absolutely. You can zoom your browser, pick a smaller brush size and carefully blur just one face, object or line of text. The rest of the picture will stay sharp.
Does blurring remove the original details forever?
Once you save the blurred version, the visible information is effectively hidden. However, you should always keep an unedited original copy for yourself if you might need it later, and only share the blurred version publicly.
