Frequently Asked Questions

How to blur a face or license plate in a photo for privacy

Upload your image and set the Blur Strength slider to high. The blur obscures faces, license plates, and text across the entire image. For selective blurring of just one area, crop the sensitive region first, blur it, then recombine in any image editor.

Can I use blur to hide personal information in a screenshot?

Yes. A strong blur obscures names, addresses, and account numbers for casual sharing. For legal redaction, note that heavy pixelation or a solid box is more secure than blur, which can sometimes be partially reversed.

How to add a soft focus or dreamy effect to a photo

Set the Blur Strength slider to a low value (5–15%) for a subtle softening that mimics a camera's soft focus or portrait lens bokeh effect. The preview updates live so you can dial in the exact look you want.

Does blurring change my image resolution?

No. The output keeps the original width and height — only the sharpness changes. PNG export is lossless.

Can I blur images on my phone without an app?

Yes. The blur tool runs entirely in your mobile browser — no app download needed. Upload, adjust the slider, and save directly to your device.

Are my images uploaded to a server?

No. Blurring runs locally in your browser using the Canvas API, so your images never leave your device.

What formats can I use?

Upload PNG, JPG, JPEG, WebP, or BMP, and export as PNG, JPG, or WebP.

How Image Blurring Works

Image blurring applies a Gaussian blur filter that averages nearby pixel values to create a smooth, softened effect. The blur radius controls how many surrounding pixels contribute to each output pixel — higher values produce a stronger blur. The intensity slider lets you blend between the original sharp image and the fully blurred result for precise control over the final appearance.

Blurring serves both practical and creative purposes in image editing. Privacy-focused blurring obscures sensitive text, faces, license plates, and other identifiable information in screenshots and photos before sharing them publicly. Creative blurring simulates camera depth-of-field effects, creates soft backgrounds for text overlays, and produces dreamy atmospheric effects. The Gaussian algorithm used here produces natural-looking results that avoid the blocky artifacts of simpler blur methods.
