Why Use Blur Image?

Precise Blur Control

Drag slider from 0px (sharp) to 100px (extremely blurry). See exactly how blurred your image will be.

Instant Preview

Watch the blur effect apply in real-time as you drag. Compare before/after side by side.

Nothing Uploaded

Your photos never leave your device. Everything runs in your browser using GPU-accelerated Canvas API.

5 Quick Presets

Tap Sharp, Subtle, Light, Medium, or Heavy for instant common blur levels.

Clear Before/After

Large comparison thumbnails show original sharpness vs blur effect. No guessing.

Works on Mobile

Fully responsive interface. Floating download button stays accessible while you adjust.

Popular Uses

Background Softening

Create depth by blurring backgrounds for portraits or product shots.

Privacy Protection

Hide license plates, addresses, faces, or sensitive text in screenshots.

Dreamy Effects

Add artistic, ethereal blur for social media or creative projects.

Video Call Backgrounds

Create custom blurred backgrounds for Zoom, Teams, or Meet.

How It Works

1

Upload Your Photo

Drag an image onto the upload area or tap to browse. Works with PNG, JPG, GIF, WebP, and most formats.

2

Drag the Blur Slider

Move right for more blur, left for less. Use presets for quick adjustments or +5px/-5px buttons for fine control.

3

Download Your Result

Hit Download to save as PNG. The filename includes your blur value (e.g., photo-blur15px.png).

Quick Tips

Start Low

Begin with 5-10px blur and increase gradually. It's easy to over-blur - you can always add more.

Check the Compare Panel

The before/after thumbnails help you gauge how much detail you're losing. Easy to lose perspective while adjusting.

For Privacy, Go Higher

If hiding sensitive info, use 40px+ blur. Text can sometimes be recovered from light blur. Better safe than sorry.

Frequently Asked Questions

This tool blurs the entire image uniformly. For selective background blur (keeping subject sharp), you'd need a tool with masking. However, you can use this to create a fully blurred version, then layer it in an editor with your original on top.
Gaussian blur produces smooth, natural-looking results by averaging pixels in a bell-curve pattern. Box blur is blockier and faster. Motion blur simulates camera movement. This tool uses Gaussian for the best quality.
For subtle background softening, try 5-10px. For dreamy/bokeh effects, 15-30px works well. For privacy (hiding text/faces), use 30-50px. For abstract backgrounds, go 50px+. The preview updates instantly so experiment freely.
Blurring doesn't compress or degrade the image - it's a reversible artistic effect. The output is saved as high-quality PNG. However, extreme blur (80px+) will obviously lose all detail by design.
No. Everything happens in your browser using the HTML5 Canvas API with GPU acceleration. Your photos never leave your device. We physically cannot see your images because nothing is transmitted.
Yes! Use 30-50px blur to hide license plates, addresses, or private text in screenshots. The higher the blur, the more unreadable the text becomes. Check the preview to ensure it's sufficiently obscured.
Blur naturally spreads pixels outward. We add padding during processing to minimize edge artifacts, but some edge softening is inherent to blur. Crop your image slightly after if needed.
Absolutely. The interface is fully responsive. On mobile, the slider works with touch, and the download button floats at the bottom for easy access.
