Privacy and redaction

Blur is the standard visual technique for obscuring sensitive information in images before sharing them publicly. License plates in street photography, faces in crowd images used for news or social media, confidential text visible in the background of a screenshot, and personal details on documents are all commonly blurred before publication. The result signals intentional redaction to the viewer without removing the surrounding context from the image.

The intensity slider controls how much the original information is obscured. Light blur softens fine detail and text while keeping shapes recognizable. Heavy blur reduces identifiable features to color and approximate shape - suitable for full anonymization of faces and text. For hard-edged censoring that is more difficult to reverse than blur, the pixelate tool offers a mosaic-style redaction.

Creative and practical backgrounds

A heavy blur transforms any photograph into a soft color field suitable as a background. This is useful for presentation slide decks, website hero sections, and social media story backgrounds where you want a muted, non-distracting backdrop that still relates thematically to the main content placed over it. The blurred version of the image creates visual coherence with the content it sits behind. Pair it with the add text tool to overlay a caption or title on the softened result.
