Frequently Asked Questions
What is an image blur tool?
An image blur tool is a photo editing application that applies various blur effects to images, including Gaussian blur for overall softening, mosaic effects for privacy protection, and selective blur for specific areas. It's commonly used for privacy, artistic effects, and professional photo editing.
How do I blur specific areas of an image?
We offer two methods for selective blurring: Selective Brush Blur - Click and drag to paint blur effects with adjustable brush size. Area Selection Blur - Click and drag to select rectangular or circular areas for precise blurring. Both methods are perfect for blurring faces, license plates, or sensitive information while keeping the rest of the image clear.
Is this image blur tool free to use?
Yes, our image blur tool is completely free to use. There are no charges, registration requirements, subscription fees, or watermarks added to your processed images. You can blur unlimited images without any restrictions.
Are my images safe when using this tool?
Absolutely. All image processing is done locally in your browser using HTML5 Canvas technology. Your images are never uploaded to our servers, transmitted over the internet, or stored anywhere. This ensures complete privacy and security for your sensitive photos.
What image formats are supported?
Our tool supports all common image formats including JPEG, PNG, GIF, WebP, and BMP. The maximum file size is 10MB. The output format will match your input format to ensure the best compatibility with your workflow.
Can I adjust the blur intensity?
Yes, you can adjust blur intensity from 1 (subtle softening) to 20 (heavy blur effect). The tool provides real-time preview so you can see changes instantly as you adjust the intensity slider. Different blur types have different intensity effects.
What's the difference between Gaussian blur and mosaic effect?
Gaussian blur creates a smooth, natural-looking blur effect ideal for artistic purposes and background softening. Mosaic effect creates a pixelated, blocky appearance that's perfect for privacy protection and completely obscuring details like faces or text.
What's the difference between area selection and brush blur?
Area Selection allows you to precisely select rectangular or circular regions by clicking and dragging, then applies blur to the entire selected area at once. Brush Blur lets you paint blur effects freehand with a circular brush. Area Selection is better for geometric shapes like license plates or signs, while Brush Blur is ideal for organic shapes like faces or irregular objects.
Can I process multiple images at once?
Yes! You can upload multiple images simultaneously and process them individually or apply the same blur settings to all images at once. The tool includes a queue system to manage multiple images, batch processing options, and automatic ZIP download for multiple images to streamline your workflow.
How does the ZIP download feature work?
When downloading multiple images, the tool automatically creates a ZIP archive containing all your processed images. Single images are downloaded directly as PNG files. The ZIP feature uses client-side compression to package your images efficiently without uploading them to any server.
Can I undo changes or reset the image?
Yes, the tool includes undo functionality to reverse your last action, and a reset button to return to the original image. You can also clear the image entirely and start with a new upload. These features help you experiment with different effects safely.
