About Blur Image Tool
There are plenty of reasons to soften an image: obscuring a face or detail, creating a backdrop for overlaid text, or generating a low-fidelity placeholder. The Blur Image Tool applies a Gaussian blur to your image so you can achieve any of these without opening a full photo editor.
Upload an image, apply the Gaussian blur, and download the softened result. Everything happens in the browser, free, with no signup and no watermark, so your image stays private, which matters when you're blurring something sensitive. The effect renders instantly, making it easy to dial in the look you need for backgrounds, redactions, or placeholder graphics.

FAQ
Can the blur be reversed?
No. Gaussian blur permanently discards detail, which is why it's effective for obscuring sensitive content. Keep your original if you need it later.
Can I control how strong the blur is?
The tool applies a Gaussian blur to the image; adjust and preview to reach the softness level your use case needs.
Is blurring secure enough to hide private information?
A strong blur obscures content visually, but for truly sensitive data consider full redaction or pixelation, since light blurring can sometimes be partially recovered.
Can I use Blur Image Tool on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
