Blur image online — what this tool does

Use this page to blur image files in the browser. Upload a photo, choose gaussian or motion blur, set the radius, and download a softened version. Processing runs in your browser, so nothing needs installing. The result includes a before/after preview so you can judge the effect against the clear original.

Blur image online free means no account, no watermark, and no software install. Your image is processed locally in your browser and is not uploaded to ImgTask's server. Image files never leave your device. Size limits still apply (200 MB per image).

Blur image to clear image — what people mean

Searches for "blur image to clear image" or "blur image to clear image online" usually want the opposite of this tool: restoring a blurry photo into a sharp one. ImgTask does not unblur or AI-sharpen. What it does offer is the clear-to-blurred direction with a side-by-side preview, so you can start from a clear image, apply blur online, and compare the clear original with the blurred result before downloading.

Blur image background

Want to soften a busy background? Full-image blur will reduce background detail along with everything else in the frame. There is no selective mask, so the subject is blurred too. For product shots or screenshots where the whole scene should look softer, that is often enough. For true portrait-style background-only blur, you would need a tool with subject masking — this one does not provide that.

When to blur an image

• Obscuring details. Soften faces, numbers, or text before sharing a screenshot or photo.
• Softening a busy background. Reduce clutter across the whole frame when selective background blur is not required.
• Motion effects. Add a directional streak for creative or presentation use.
• Preparing public posts. Make fine detail less readable while keeping the overall composition.

Formats and limitations

Accepted uploads: JPEG, PNG, WEBP, GIF, BMP, TIFF, AVIF, HEIC. Max 200 MB.

Limitations: Blur applies to the full image — not a masked background only. Heavy radii remove more detail. This tool cannot turn a blurry photo into a clear one. HEIC inputs are processed and typically returned as JPEG.

Privacy: Your image is processed locally in your browser and is not uploaded to ImgTask's server. Image files never leave your device. No account is needed and results carry no watermark.
