Image Blur Guide
Reference for using Image Blur with supported inputs, browser limits, common mistakes, and related AscendLab image tools.
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.
What this tool does
Apply adjustable blur to an image in the browser for soft backgrounds, previews, thumbnails, and lightweight visual obfuscation.
Supported input
- JPG, PNG, WebP, and browser-readable images
- Adjustable blur radius
- PNG, JPG, or WebP export
Not a fit for
- Selective region blur
- Secure redaction
- Batch blur workflows
Data handling and processing behavior
Processing is handled in the browser for this tool based on the current public implementation. Avoid using sensitive images unless you have reviewed the implementation and your own data handling requirements.
Step-by-step use
- Open Image Blur.
- Choose a browser-readable local image or provide the required source input.
- Review the supported formats, file size guidance, and output settings.
- Generate the output or metadata summary.
- Download the result or copy the summary into the next workflow.
Practical examples
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 errors
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.
Limits
- 25MB recommended limit.
- Browser memory and image decoder support can affect large files.
- Canvas-based outputs can change metadata, color profile behavior, and compression.
- Keep the source image when exact fidelity, audit trails, or metadata preservation matter.
