How does the image blur tool work?

This tool uses Gaussian blur algorithm to apply smooth, professional-quality blur effects to your images. You can choose to blur the entire image or select specific areas by clicking and dragging on the canvas. Adjust the blur intensity with the slider (1-50px radius) to control the amount of blur. All processing happens locally in your browser, so your images never leave your device, ensuring complete privacy.

What can I use image blur for?

Image blur has many practical uses: protecting privacy by hiding faces, concealing sensitive information like documents or IDs, blurring license plates in photos, censoring personal data, creating professional-looking backgrounds with depth of field, hiding watermarks or logos, obscuring unwanted elements, artistic effects and photography, NSFW content censorship, and much more. It's an essential tool for privacy protection and creative editing.

What's the difference between Full Image and Select Area modes?

Full Image mode applies blur to the entire photo uniformly - useful for creating overall soft effects or quick privacy protection. Select Area mode lets you choose specific regions to blur by drawing rectangles on the image - perfect for selectively hiding faces, license plates, or sensitive text while keeping the rest of the image sharp. Select Area mode gives you precise control over what gets blurred.

How do I adjust blur intensity?

Use the Blur Intensity slider to control the amount of blur applied. Low values (1-10px) create subtle blur effects, medium values (10-25px) provide moderate blur suitable for most privacy needs, and high values (25-50px) create strong blur for maximum obscuration. You can preview the effect before downloading to find the perfect intensity for your needs.

What image formats are supported?

The tool supports all common image formats including JPEG/JPG, PNG, and WebP for input. The output maintains your original format, preserving image quality. PNG format is recommended if you need transparent backgrounds. The tool handles images up to 10MB in size.

Is my data private and secure?

Yes, absolutely! All image processing happens directly in your web browser using JavaScript and HTML5 Canvas. Your images are never uploaded to any server, and no data is collected, transmitted, or stored anywhere. This ensures complete privacy and security for your photos, especially important when blurring sensitive information. You can even use this tool offline once the page is loaded.

Can I blur multiple areas in one image?

Currently, you can select one rectangular area per processing. However, you can apply blur multiple times: process the image once, download it, then upload the result and blur another area. This way you can progressively blur multiple different regions. Make sure to save each version as you work.

How do I select the area to blur?

In Select Area mode, simply click and drag on the canvas to draw a rectangle over the region you want to blur. The selected area will be highlighted with a blue border. You can click 'Clear Selection' to start over if needed. The selection is proportional to the original image size, so even if the preview is scaled, the blur will apply to the correct area in the full-resolution image.

Can I use blurred images commercially?

Yes! The tool itself is completely free and there are no restrictions on how you use the resulting images. You retain all rights to your images. The tool simply applies a blur effect - you own the original content and the edited result. However, make sure you have the rights to edit the original images you process.

Does this work on mobile devices?

Yes! The tool is fully responsive and works on smartphones and tablets. You can use touch gestures to select areas on mobile devices. Simply touch and drag to draw the selection rectangle. However, for best precision when selecting small areas, we recommend using a desktop or laptop computer with a mouse.
