Common Uses for Image Blurring
Blur faces, license plates, addresses, and personal information in photos before sharing them publicly online or in documents.
Create soft, dreamy photo effects. Blur backgrounds to make subjects stand out, mimicking the bokeh effect of professional cameras.
Create blurred background images for website heroes, app interfaces, and presentation slides where text needs to be readable over imagery.
Simulate depth-of-field effects on images that were shot without a blurred background, bringing focus to the main subject.
Anonymize people in group photos, screenshots, or event pictures before sharing in presentations, reports, or social media.
Blur sensitive information in screenshots, contracts, or official documents before sharing them with external parties.
How to Use the Blur Tool

Choose your output format (PNG or JPG) and click Download. The file saves directly to your device with no watermark.
Frequently Asked Questions
Is my image sent to a server?
No. All blur processing happens entirely in your browser using the HTML5 Canvas API. Your image never leaves your device and is never stored or shared.
What blur types are available?
Full Image Blur applies uniform blur across the entire image. Edge Blur (Vignette) blurs the edges while keeping the center sharp, creating a focus effect. Center Focus blurs the outer areas while keeping the center clear, simulating shallow depth of field.
Can I adjust the blur intensity?
Yes. The blur intensity slider controls the blur radius from 1px (very subtle) to 50px (very heavy). The preview updates instantly as you adjust the slider.
What is the difference between PNG and JPG output?
PNG preserves full quality with no compression artifacts but produces larger files. JPG uses compression to produce smaller files but may show artifacts at very high blur levels or low quality settings. PNG is recommended for most uses.
Is there a watermark on the downloaded image?
No. The downloaded image contains only your original photo with the blur applied — no watermark, no logo, and no attribution.
Can I blur faces or specific areas?
This tool currently applies blur to the full image or defined regions (edges or center). For precise face-only blurring, use the Edge Blur type and position your subject in the center, or apply the full blur effect at the area you want hidden.
