What is Metadata?
Metadata is information about a file rather than its visible content, such as its author, creation time, image dimensions or camera settings.
How it works
Metadata can be embedded inside a file or maintained separately by the filesystem. Embedded metadata travels with the file wherever it goes: photos carry EXIF and XMP fields, PDFs and Office documents carry author names, titles, software versions and sometimes revision history. Filesystem metadata, such as the modified date shown in a folder, usually doesn’t survive being emailed or uploaded.
Some fields are useful for organizing work, while others reveal information you didn’t intend to share: where you live, which device you own, who drafted a document or which earlier version it came from.
Metadata vs EXIF
EXIF is one specific kind of image metadata, focused on camera settings and location. “Metadata” covers every kind, including document properties, XMP editing history and IPTC captions. A tool that removes EXIF from a photo won’t touch the author field in a Word document, so check each file type you share.
A practical example
A photo may contain GPS coordinates even when no location is visible in the picture. A PDF may list the name of the person who created it in its document properties.
What to watch out for
Removing one type of metadata doesn’t guarantee removal of every identifying detail. Metadata can also be edited, so timestamps aren’t reliable proof of when content was created.

- EXIF Viewer · See camera, settings and location data
- EXIF Remover · Strip metadata without touching image quality
- Redact Image · Cover text and faces so it can’t be undone

Common questions
How do I see a file’s metadata?
On Windows, right-click the file and open Properties, then Details. On a Mac, use Get Info. For photos, an EXIF viewer shows far more fields, including GPS and camera settings.
Does taking a screenshot remove metadata?
It removes the original photo’s EXIF, since the screenshot is a new image. The screenshot can have its own metadata, such as device and time, but not the original location.
Should I remove metadata before sharing files?
For photos taken at home and documents sent outside your organization, it is a sensible habit. Keep the originals, since metadata such as dates is useful for your own records.
