FAQ
- Which tags are removed?
- Patient name, ID, birth date/time, age, address, phone, ethnic group, comments, plus referring/performing physician, institution and accession number. Pixel data is left unchanged.
- Are my files uploaded to anonymize them?
- No. The DICOM bytes are parsed and edited entirely in your browser; nothing is sent to a server.
- Is this a certified de-identification?
- It removes the standard identifying tags but is not a certified, exhaustive de-identification — it cannot remove identity burned into the image pixels or every private tag. Review before sharing.
