MetaLyzer is a powerful client-side web application designed to reveal the hidden digital DNA inside your files. It extracts deep metadata (EXIF, XMP, IPTC, GPS) from images, videos, and documents entirely within your browser — no data is ever uploaded to a server.

Powered by a custom implementation of ExifReader, capable of extracting metadata tags that standard viewers often miss.

While MetaLyzer is excellent for revealing hidden metadata, sometimes you need to remove sensitive information before sharing files publicly.
For metadata scrubbing (GPS location, camera serial numbers, timestamps), we recommend:
Use MetaWipe to permanently strip metadata from your files before uploading them to social media or public platforms.
