Frequently Asked Questions

How do I blur part of an image?

Upload your image, select the blur tool, then use your mouse to draw over the area you want to blur. You can adjust the brush size and blur intensity. For precise areas, use rectangle or circle selection tools.

Can I blur faces automatically?

Yes! Our tool can detect and blur faces automatically. Perfect for privacy protection in photos.

What's the difference between blur and pixelate?

Gaussian blur creates a smooth, soft effect - great for backgrounds and artistic purposes. Pixelate creates a blocky, mosaic effect - ideal for censoring text, faces, or sensitive information where you want to make content unrecognizable.

Is it really private? Do you store my images?

No, never! All blurring happens locally in your browser. Your images never leave your device, are never uploaded to any server, and we have zero access to them. This is especially important when blurring sensitive information.

Can I blur multiple images at once?

Yes! Select multiple images and apply the same blur settings to all. Great for batch processing photos from events, anonymizing datasets, or preparing multiple images for publication.

What image formats are supported?

We support all major formats: JPG, PNG, WebP, GIF, BMP, and TIFF. PNG transparency is preserved when blurring non-transparent areas.

Can I undo if I make a mistake?

Yes! You can undo/redo any changes. You can also reset the image and start over at any time before downloading.

Is there a limit on file size?

You can blur images up to 50MB. For larger files, we recommend resizing them first using our resize tool, then applying blur effects.
