Free Online Image Blur Tool

No! All image processing happens entirely in your browser using Canvas API. Your images never leave your device, ensuring complete privacy and security. We do not store, transmit, or have access to any images you blur using this tool.

Our blur tool supports the most common image formats including JPG, JPEG, PNG, and WEBP. The maximum file size is 10MB. For best results, we recommend using high-resolution images that will maintain quality after blurring.

Yes! You can adjust the blur brush size using the slider from 10px to 100px. Larger brush sizes create wider blur areas and slightly stronger blur effects. You can also apply multiple passes over the same area to increase the blur intensity.

Simply click the "Reset Image" button to restore the original, un-blurred image and start over. You can reset as many times as you need. If you want to work on a different image, use the "Upload New Image" button.

Absolutely! The blur tool is fully responsive and supports touch gestures on mobile devices and tablets. Simply tap and drag with your finger to blur areas on touchscreen devices. The interface automatically adapts to your screen size for the best experience.

Common uses include: hiding personal information on documents before sharing, obscuring sensitive data on resumes for public portfolios, blurring faces for privacy in photos, redacting confidential information in screenshots, and protecting license plates or addresses in images posted online.
