What is Image Blur Tool?
Blurring is a practical way to protect privacy, soften backgrounds, or reduce visual distractions in images. It is commonly used for redacting sensitive data in screenshots and photos.
Image Blur Tool lets you apply controlled blur quickly in the browser for fast redactions or design effects.
Sensitive details are easy to expose
Screenshots and photos often include personal data, faces, or private identifiers that should not be shared.
Manual blurring in full editors is slow when you need a quick redaction.
Heavy blur can ruin the rest of the image if not applied carefully.
Focused blur with fast local processing
Apply blur to protect details while keeping the rest of the image usable.
Local processing ensures sensitive content never leaves your device.
Blur is not irreversible protection; for strong privacy needs, remove or crop the content entirely.
