What is Image Metadata?

Metadata is essentially "data about data." For images, metadata includes information embedded within the file, such as:

• ImageDescription: A brief description of the image content.

• Artist: The creator or photographer’s name.

• Copyright: Ownership and usage rights.

• DateTimeOriginal: When the image was captured.

• Make and Model: The camera or software used.

• UserComment: Additional notes or comments.

Metadata is stored in formats like EXIF (Exchangeable Image File Format), IPTC, or XMP, and is critical for:

• Searchability: Helps search engines and databases index images.

• Organization: Simplifies asset management in large collections.

• Attribution: Ensures proper credit to creators.

• SEO: Improves image visibility in search engine results.

With Picnie’s API and no-code tool, adding this metadata is seamless, even for non-technical users.
