Mosaic blur is one of the simplest, safest ways to hide faces, private info, or sensitive areas in your content. Here's how to apply the mosaic blur effect in seconds using an online mosaic generator and blur tool like BlurMe face blur.

How to Add Mosaic Blur to Image

The quickest way to apply pixel mosaic is using BlurMe, which works in any browser and doesn’t require downloading any mosaic app.

Step-by-Step: Apply Mosaic Blur to an Image

1. Go to BlurMe Studio
   Open BlurMe online blur editor in your browser.

2. Upload your photo
   Drag and drop any image.

3. Choose Pixelation

• Use AI Blur if you want the system to mosaic blur automatically.
• Use Custom Blur to draw a box or paint over the exact area.

4. Adjust the pixel size

5. Download your mosaic image
   Export in high resolution instantly.

Step-by-Step: Apply Mosaic Blur to Video

1. Upload your video to BlurMe
2. Pick AI Blur for automatic detection

3. Select the pixel size

4. Preview in real time. Export the video with pixel mosaic censoring applied

This is the fastest method for creators who regularly upload clips with faces, names, screens, or private areas that need censoring.

How to Do Mosaic Blur Manually (Precision Mode)

Sometimes you don’t want to pixelate a whole face—you want a small area:

• usernames
• license plates
• documents
• screens
• background objects
• logos

In BlurMe:

1. Choose Custom Blur
2. Select Pixelation as your mosaic blur effect
3. Draw a box over the exact area
4. Increase or decrease pixel strength
5. Save

This mode acts like a professional mosaic censor tool.

How to Use Mosaic Blur Creatively

Beyond censoring, many people use the mosaic blur effect for aesthetic edits:

• pixel portrait art
• blocky retro gaming looks
• stylized profile photos
• mosaic backgrounds
• abstract pixel grids

In BlurMe, simply select Full-Screen Blur to convert the entire photo into a pixel mosaic aesthetic.

Mosaic Blur Tips for Cleaner Results

These tips help avoid amateur-looking censorship:

1. Use larger blocks for faces

Small mosaic blocks can still reveal identity. Use bigger squares.

2. Don’t over-pixelate text

Start with medium pixel size so the area isn’t a solid square.

3. Follow motion paths for video

AI face tracking saves hours of manual work.

4. Use mosaic blur instead of Gaussian blur

Soft blur can still be partially reversed; pixel mosaic is safer.

5. Always preview at mobile resolution

Pixelation can look different on small screens.
