Apply adjustable visual blur to an image and download the result locally.

Blur Image
Images and pixels remain in browser memory and are never uploaded to any server.
The practical guide
Use blur for appearance—not as a security control.
The tool applies a browser-rendered blur effect to the full image and lets you review the processed output before saving.
Output is re-rendered
The downloaded image contains the blurred pixels produced by the canvas rather than an editable CSS filter instruction.
Blur is not secure redaction
Strong blur may still reveal shapes or be vulnerable to inference. Permanently remove sensitive PDF content with Redact PDF and crop private image areas when appropriate.

Questions, answered
Frequently asked questions
Can blur securely hide text or faces?
No guarantee is provided. Blur is a visual effect, not secure redaction.
Does the whole image get blurred?
Yes. This implementation applies one adjustable blur level to the complete image.
Will the original file be changed?
No. The source remains untouched; the tool creates a new downloadable image.
Is the image uploaded?
No. Blur rendering and export happen in your browser.
