Quick answer

Use Image Blur Tool to soften an image or create a blurred visual background.

Blur can hide some detail, but it is not a secure redaction method for sensitive data.

Best inputs

Background images

Create soft hero or card backgrounds.

Screenshots

Reduce distracting detail in examples.

Thumbnails

Make text overlays easier to read.

Blur method
The browser draws the image through a canvas filter and exports a new file.
Higher radius creates stronger blur.
Canvas filter support depends on the browser.
Output dimensions match the source unless resized elsewhere.
Example, Assumption, and Limitation
Use the result as a practical estimate or transformation, then confirm edge cases for critical work.

Background card

Blur a product screenshot before placing text over it.

Soft preview

Create a less distracting article thumbnail.

Limit

Do not use blur alone to hide confidential information.

Common mistakes to avoid
These checks help prevent bad outputs, failed exports, and confusing results.

Blurring secrets instead of removing them

Sensitive information should be cropped or removed, not merely blurred.

Over-blurring small images

Small images can become muddy quickly.

Skipping contrast checks

If text sits over the blurred image, check readability afterwards.

Common use cases
Use these scenarios to decide which input, assumption, or follow-up tool fits this specific task.

Backgrounds

Prepare soft image backgrounds.

Docs thumbnails

Reduce detail behind labels.

Social cards

Create calmer cover images.

Preview masking

Hide nonessential details before sharing.

Frequently asked questions

Does Image Blur Tool upload my image?

The public tool is designed for browser-side processing based on the current implementation. Avoid using sensitive images unless you have reviewed the implementation and your own data requirements.

Will metadata be preserved?

Canvas-based exports usually change or remove metadata. Keep the original file when metadata, color profiles, or exact camera details matter.

Why can a browser image tool fail?

Very large files, unusual formats, limited memory, unsupported browser encoders, or SVG features the browser cannot render can cause failures.

When should I use Image Blur Tool?

Use it when you need a soft visual effect or lightweight obfuscation for non-sensitive content.

Suggested workflow

Image publishing workflow

Inspect the source, prepare the output, then compress or convert for the final destination.
