Blur Background by Vignra is an online photo-background blurring tool. Its free basic mode needs no account and handles subject detection, background blur, strength adjustment, before-and-after comparison, and PNG export for one static photo in the browser without automatically uploading the source image. For difficult edges, signed-in users can explicitly confirm a 10-Credit AI Refined task that privately uploads the photo so cloud AI can create a subject mask; final blur and compositing still run in the browser. The product does not promise background replacement, video or batch processing, and should not be treated as reliable redaction.

FAQ
No. Free Basic processes the photo in the current browser, and a local-processing failure does not silently fall back to cloud upload.
AI Refined requires sign-in and an explicit confirmation of the 10-Credit task. The source is uploaded privately for cloud AI to create a subject mask, while final background blur and compositing still run in the browser.
It is not recommended. Background blur is designed for visual focus, not reliable anonymization or secure redaction.
