Blur Images Online in Seconds – Free, No Signup Required

Our free online blur tool gives you three powerful modes to soften, obscure, or artistically enhance your images. Full Blur applies a smooth, uniform Gaussian blur across the entire image — perfect for hiding sensitive information, creating background textures, or producing a dreamy soft-focus effect. Background Blur blurs the outer edges while keeping the central area sharp, simulating a shallow depth-of-field bokeh look. Edge Blur softens only the perimeter of the image, creating a vignette-style fade that draws attention to the center. All modes work in your browser with no installation needed.

Three Blur Modes for Every Use Case

Full Blur is ideal for redacting documents, obscuring faces in screenshots, or creating soft background graphics. Background Blur mimics the portrait-mode effect found in smartphone cameras, making your subject pop against a gently blurred background — great for profile photos, product images, and social media content. Edge Blur creates an elegant, dreamy vignette that is popular in artistic photography, wedding photos, and vintage-style edits. The intensity slider gives you precise control over how strong or subtle the effect appears, from a barely noticeable softness to a heavy, dramatic blur.

When and Why to Use Image Blur

Image blur is a versatile technique with countless practical and creative applications. Privacy-conscious users rely on blur to redact names, addresses, license plates, faces, and other personal information before sharing screenshots or photos online. Designers use blur to create depth, focus, and visual hierarchy in compositions. Marketers apply background blur to make product images stand out. Social media creators use edge and background blur to add professional polish to their posts. Blur also helps reduce visual noise in busy images, making the main subject clearer and more compelling.

Privacy & Security: 100% In-Browser Processing

All blur operations are performed locally in your browser using HTML5 Canvas and JavaScript, with no data ever transmitted to an external server. Whether you are blurring a confidential document, a medical image, personal photos, or business graphics, your files remain entirely on your device throughout the process. This makes our tool safe to use in professional environments, healthcare settings, and any situation where data privacy is paramount. There is no account to create, no files to upload, and no personal information collected.

Got Questions? We have you covered

Full Blur applies a uniform Gaussian blur to the entire image. Background Blur keeps the center of the image sharp and blurs the surrounding area to simulate a bokeh depth-of-field effect. Edge Blur softens only the border region of the image, creating a vignette-style fade effect toward the edges.

Use the Blur Intensity slider to set the strength of the effect. A low value produces a subtle, gentle softness, while a high value creates a strong, heavily blurred result. You can preview the effect before downloading by adjusting the slider and reprocessing the image.

The tool supports JPG (JPEG), PNG, and WebP formats. These cover the vast majority of photos and web graphics. You can blur up to 10 images at once in a single batch operation, with all images processed using the same blur mode and intensity settings.

Yes. The Background Blur mode blurs the outer area of the image while keeping the center sharp, which approximates the bokeh depth-of-field effect seen in portrait photography. For best results, use an image where your subject is centered in the frame.

No. All image processing happens entirely within your browser using client-side JavaScript and HTML5 Canvas. Your images are never sent to any external server at any point. This ensures complete privacy, making the tool safe to use with sensitive, confidential, or personal images.
