What is the blur image tool online, and how does it work?

Our blur image tool is a 100% browser-based image blur tool that lets you blur photos online directly in your web browser. There's no need to download software or upload images to a server. All processing happens on your device, ensuring fast, private, and secure image editing. You can choose from various blur types like Selective Blur Image, Global Blur Image, Pixelate Blur Image, or Blur Sensitive Info, and apply them instantly.

Is this blur image tool really free, and are there any hidden limits?

Our image blur tools is completely free to use with no hidden fees. You can process images without creating an account, and there are no watermarks.

How can I blur a face in a photo online for free?

Use our AI-powered "Blur Faces" tool. It automatically detects all faces in your image and allows you to apply Gaussian blur or pixelate blur with one click. You can also manually refine the result with our brush and eraser tools. Yes, it's completely free to blur faces online with no watermarks or sign-ups required.

Is it possible to blur text in an image without downloading software?

Absolutely. Our "Blur Text" feature uses AI to automatically find and blur text in any image. You can choose between weak blur, strong blur, or pixelation effects. For precise control, switch to manual mode to blur specific text areas or erase blur where needed - all directly in your browser.

I need to hide sensitive information in a document. Can your tool blur personal information securely?

Yes. Blur Sensitive Info is designed for this exact purpose. It uses AI to identify and blur private details like IDs, numbers, or addresses. You can select Gaussian or pixelate blur types, and all processing is done locally on your computer - your data never leaves your device, making it ideal for secure document redaction.

What's the difference between selective blur image and global blur image?

[1] Selective Blur Image lets you manually paint blur onto specific areas of an image using a brush or shapes, perfect for precisely protecting privacy-sensitive content in defined regions. [2] Global Blur Image applies a uniform blur across the entire image with one click. You can then use the eraser to reveal specific areas, ideal for quickly creating background blur to highlight a subject or achieving depth-of-field (bokeh) effects.

Are the blur effects, especially pixelation blur, safe from AI restoration?

Yes. Our pixelation blur (and other blur types) is designed to be irreversible, effectively destroying the original pixel data. This ensures that blurred content cannot be recovered by AI image restoration tools, providing a robust layer of privacy protection for sensitive information.

What image formats do you support, and how do you handle image privacy?

We support uploading and exporting in the most common and efficient formats: JPG, PNG, and WebP. To ensure maximum privacy, our tool automatically strips all EXIF metadata (such as GPS location, camera model, and creation date) from your images during processing. This means you can blur images online with the confidence that not only the visible content is protected, but also the hidden data that could compromise your privacy.

Choose Gaussian Blur (natural look) or Pixelate Blur (strong privacy), then click "Apply Blur to All Faces". 4. Use Manual Drawing Mode to refine with the Blur Brush (add blur) or Eraser (remove blur). 5. Export your image. EXIF metadata is removed by default for privacy. *All processing happens in your browser—no uploads, no data stored.*

Our Blur Face tool uses AI-powered face detection that automatically identifies every face in your image—regardless of how many faces are present. This eliminates the need for time-consuming manual selection, allowing you to blur all faces with one click while maintaining perfect accuracy even in group photos and complex scenes.

Yes, our advanced detection algorithm recognizes faces across multiple orientations (front, side, tilted) and can identify partially visible faces. The system automatically adjusts detection sensitivity to catch most visible facial features, though extremely obscured faces (less than 30% visible) may require minor manual refinement.

You can choose between two professionally optimized blur types: • Gaussian Blur: Creates smooth, natural-looking anonymization ideal for photos and videos • Pixelate Blur: Applies block-based pixelation that provides stronger privacy protection and resists AI reconstruction attempts.

Our Manual Drawing Mode lets you easily add blur to any missed areas: • Blur Brush: Paint additional blur onto undetected faces or facial features • Eraser Tool: Precisely remove blur from non-facial areas if over-detection occurs • Adjustable Brush Size: Control application area for detailed refinement

No—the tool processes all detectable faces regardless of quantity. Whether it's a single portrait or a crowd photo with dozens of faces, the AI will identify each one and apply your selected blur effect consistently across the entire image.

Unlike cloud-based face blurring services that upload your images to external servers, our tool processes everything 100% in your browser. This means your photos never leave your device, facial data is never transmitted externally, and all EXIF metadata can be optionally removed during export for complete privacy protection.

Yes, the Manual Drawing Mode allows you to customize blur strength for individual faces or facial regions. After automatic blurring, simply use the Blur Brush with adjusted strength settings to enhance or reduce effects on specific areas.

Absolutely. We recommend completing your face blurring first, then: 1. Export your processed image 2. Re-upload it to additional tools like Selective Blur Image or Pixelate Blur Image 3. Apply further privacy protection as needed This sequential approach maintains 100% local processing while allowing comprehensive privacy editing.

No—all face detection occurs locally in your browser with no data storage, transmission, or AI training. The detection model runs entirely on your device, and all processing data is cleared immediately after you close the browser tab.
