Blur Sensitive Details or Faces Before Sharing Your Photos
A screenshot can reveal more than you intended, and a photo taken in a public place may include people who do not want their faces shared online. An address, license plate, email address, or account reference can also appear in an image without immediately catching your attention. Before publishing or sending a photo, it helps to decide which details should remain visible and which ones should be obscured.
Imagesmint's Blur Image tool offers two approaches to image editing: manual blur for areas you select yourself, and AI Faces, which uses artificial intelligence to help detect and blur faces. You can also apply blur to an entire image when you want a softer appearance for a background or a graphic design.
These options serve different purposes. AI Faces is useful when faces are the main concern, especially in photos containing several people. Manual blur gives you direct control over specific areas, including text, license plates, and other details that are not faces. Using both approaches in the same editing session can help you prepare an image for sharing while keeping the parts you want to show intact.
The editor accepts JPG, PNG, and WebP images. If your photo is saved as HEIC or AVIF, convert it first with our HEIC to JPG converter or AVIF to JPG converter.
AI Faces: Blur Faces Without Selecting Every Face Manually
When a photo contains a group of people, manually placing a selection over every face can become repetitive. The AI Faces feature is designed to help with this task by using AI-assisted face detection to identify faces for blurring. It can be a practical starting point for group photos, public-event pictures, and images that include people in the background.
This approach is particularly useful when you want to reduce the visibility of people's faces without blurring the entire scene. For example, a photo may still communicate the atmosphere of a gathering or show the setting of an event even when the faces of individual attendees are obscured.
Automatic detection should not be treated as a guarantee that every face will be found. Small faces, unusual angles, partial obstructions, and poor lighting can affect detection. Review the processed image carefully and check the areas that matter to you. If a face has not been blurred as intended, or if another sensitive detail remains visible, use manual blur to address it.
When is AI Faces a good choice?
- Group photos: Help reduce the need to select every visible face individually.
- Street and public-event photography: Prepare a photo for publication when the people in the background are not the focus.
- Social media posts: Make faces less prominent before sharing a scene with a wider audience.
- Photos containing background faces: Preserve the overall setting while reducing the visibility of people who are not central to the image.
Manual Blur for Text, License Plates, and Specific Details
Not every private detail can be identified as a face. Screenshots may contain phone numbers, email addresses, order references, financial figures, or account names. Photographs may show vehicle plates, house numbers, or other identifying information. In these situations, manual blur allows you to place the selection directly over the area you want to edit.
You can position the selection frame, adjust its dimensions, choose the blur intensity, and apply the effect to that specific region. The rest of the image can remain visually unchanged, making this approach useful when you want to retain the surrounding context.
Manual editing also gives you more control when only one face needs to be blurred or when you want to refine a result produced by AI Faces. For a photo containing both people and confidential text, you can use AI-assisted face blurring first, then inspect the image and manually blur any remaining sensitive areas.
Choosing the Right Blur Intensity
The editor offers quick settings of 3 px, 8 px, 15 px, and 25 px, together with an intensity slider that reaches 50 px. The most suitable setting depends on the image's dimensions, the size of the selected area, and the amount of detail you need to obscure.
- 3 px — Light blur: A subtle effect for softening details without substantially changing the appearance of the selected area.
- 8 px — Moderate blur: A useful starting point when you want a softer look while retaining some of the original shapes.
- 15 px — More pronounced blur: Worth testing on small details or text in some screenshots, depending on the image size and content.
- 25–50 px — Stronger blur: Useful when a more visible effect is needed, especially on larger images. The actual result still depends on the content being edited.
These values are not universal privacy levels. A 15 px blur may have a strong effect on a small screenshot but a less noticeable effect on a high-resolution photograph. For faces, numbers, and confidential text, judge the actual preview rather than assuming that a particular slider value guarantees that the information is hidden.
How to Blur Multiple Areas in One Image
-
Open your image:
Upload a JPG, PNG, or WebP file from your device.
-
Choose your editing method:
Use AI Faces when your main goal is to blur faces, or choose manual selection to work on a particular area.
-
Position the selection frame:
For manual editing, drag the blue frame over the detail you want to obscure. Use the handle in its bottom-right corner to adjust the selection's width and height.
-
Adjust the intensity:
Select one of the quick presets or move the intensity slider to choose the amount of blur.
-
Apply and review:
Click Apply and inspect the edited region. Repeat the process for other areas that need attention.
-
Undo an edit if necessary:
Use the Undo button or
Ctrl + Z to return to an earlier state within the available editing history. The editor retains up to five recent applied modifications.

Download the result:
Once you have reviewed the image, click Download to save your edited file.
Blur the Entire Image for a Softer Background
Selective blur is useful when you need to hide particular details, but a full-image effect serves a different creative purpose. Blurring the entire image can soften a busy photograph and make it more suitable as a background for a title, presentation, banner, or social media graphic.
To use this approach, enable Blur entire image in the Mode panel and click Apply. Unlike a manually selected blur, this mode affects the full image. Review the result at the size where it will be used, since an effect that looks balanced in a large preview may seem too strong in a small thumbnail.
Blur, Pixelation, or Cropping: Which Is Better?
These editing methods create different results. Blur softens details and transitions, while pixelation replaces finer detail with visible blocks of color. Cropping removes parts of the image from the frame rather than changing their appearance. The best option depends on whether you want to soften a region, create a mosaic effect, or remove an unwanted section completely.
- To blur faces: Start with AI Faces, then review the result and use manual editing for any areas that still need attention.
- To hide text or a license plate: Use manual blur to target the specific region.
- For a mosaic-style effect: Try our Pixelate Image tool.
- To remove something near the edge: Use the Image Cropper if removing that part will not exclude important content.
- To separate a subject from its background: Try our AI Background Remover.
Image Privacy Goes Beyond the Visible Picture
A visual edit does not necessarily remove every piece of information associated with a file. Blurring a face or house number changes how that area appears, but it does not automatically remove metadata that may describe the image, the device used to take it, or its location.
Before sharing a sensitive image, consider both the visible content and the information stored alongside the file. Our Remove Image Metadata tool can help remove supported metadata fields. This is a separate step from blurring and does not replace a review of the image itself.
If your edited image is too large for your intended use, you can also try the Image Compressor. When you need to change a PNG image to WebP, use the PNG to WebP converter.
Frequently Asked Questions About AI Faces and Image Blur
What is the difference between AI Faces and manual blur?
AI Faces uses artificial intelligence to help detect faces for blurring. Manual blur lets you select an image region yourself, whether it contains a face, text, a number, or another detail. AI Faces is useful for face-focused editing, while manual selection provides more direct control over individual areas.
Can AI Faces be used on group photos?
Yes, it is particularly relevant to images containing several people because it can reduce the need to select every face individually. However, detection may not find every face in every image, so the final result should be reviewed before publication.
Can I blur faces and text in the same photo?
Yes. You can use AI Faces for face-focused editing and then manually blur other details, such as an email address or license plate. Reviewing the complete image helps you identify any information that still needs to be obscured.
Does blurring guarantee that a face or text can never be identified?
No. The result depends on the blur intensity, the image's content, and the detail that remains visible. Blur should not be treated as a universal guarantee of anonymity. For highly sensitive information, consider an opaque redaction method and inspect the exported image before sharing it.
Does blurring remove GPS information from an image?
No. Blur changes the visual appearance of an image but does not necessarily remove its metadata. If you also want to remove supported metadata fields, use a dedicated metadata-removal tool before sharing the file.
Does blur change an image's resolution?
Not necessarily. Blur changes the appearance of the details, whereas resolution refers to the image's pixel dimensions. These are separate aspects of an image, even though both can affect how sharp it looks.
