Why Blur Images?

🔒 Screenshot Privacy

Sharing screenshots at work or online? Blur out emails, passwords, account numbers, personal names, and other sensitive data before sending.

🛡️ Redact Sensitive Data

Unlike black bars, blur is irreversible — the original pixel data cannot be recovered. This makes it ideal for permanently redacting confidential information.

🎨 Creative Effects

Create soft, dreamy backgrounds for text overlays, social media posts, or presentation slides with adjustable Gaussian blur.

⚡ Instant & Free

No signup, no limits, no watermarks. Your images stay on your device — they are never uploaded to any server.

Frequently Asked Questions

How do I blur sensitive information in a screenshot?+
Upload your screenshot, adjust the blur intensity slider to fully obscure sensitive data like emails, passwords, or personal information, then download the blurred image. All processing happens in your browser for maximum privacy.
What type of blur does this tool use?+
This tool applies a Gaussian blur via the Canvas API filter property. You can adjust the blur radius from 1px (subtle) to 20px (heavy) using the slider.
Can I blur just part of an image?+
This tool applies blur to the entire image. For selective area blurring, try ScreenSnap Pro which lets you draw blur regions directly on screenshots.
Is the blur irreversible?+
Yes. Once you download the blurred image, the blur is permanently baked into the pixels. The original data cannot be recovered from a blurred image, making it safe for redacting sensitive content.
