Frequently asked questions
Can I blur faces automatically?
Yes. Click Scan and RedactPix detects all faces using on-device AI. Each detected face gets a blur box you can review, adjust, or remove.
How is this different from Instagram or Snapchat blur?
Social media blurs are applied to images that are already uploaded to their servers. RedactPix applies blur entirely on your device — the image is never uploaded — so it is safe for sensitive documents and private photos.
Can I blur the background of a photo?
RedactPix focuses on privacy redaction rather than aesthetic background blur. You can manually draw blur boxes over any area including backgrounds, but there is no automatic subject-separation feature.
