About ExifMeta
Technology, metadata standards, and technical specifications
Overview
ExifMeta is a free web-based metadata extraction platform powered by ExifTool. It reads and displays metadata from digital files using industry-standard parsing libraries, supporting EXIF, IPTC, XMP, ID3, and dozens of other metadata formats.
Unlike desktop applications, ExifMeta processes files server-side and returns structured metadata through a web interface. Files are automatically deleted after processing, ensuring privacy while providing professional-grade metadata analysis accessible from any device. Try the metadata viewer.
ExifTool Integration
ExifMeta is built on ExifTool, created by Phil Harvey. ExifTool is widely regarded as the most comprehensive metadata extraction tool available, used by organizations including Adobe, Google, and law enforcement agencies worldwide.

Metadata Standards Explained
Digital files can contain multiple types of metadata, each following different standards. ExifMeta extracts and displays all available metadata types from your files. See our EXIF definition and Metadata definition for quick overviews.
EXIF (Exchangeable Image File Format)
The primary metadata standard for digital cameras. EXIF data is written at capture time and includes camera settings, timestamps, and optional GPS coordinates.
Make, Model, DateTime, ExposureTime, FNumber, ISO, FocalLength, GPSLatitude, GPSLongitude
JPEG, TIFF, RAW (CR2, NEF, ARW, DNG), HEIC, WebP
IPTC (International Press Telecommunications Council)
Industry standard for news and publishing metadata. IPTC tags store editorial information like captions, keywords, copyright, and creator credits.
Headline, Caption, Keywords, Creator, Copyright, City, Country, DateCreated
News agencies, stock photo services, digital asset management systems
XMP (Extensible Metadata Platform)
Adobe's XML-based metadata format. XMP is extensible and can store custom metadata schemas, making it popular in creative workflows and digital asset management.
Creator, Rights, Label, Rating, CreateDate, ModifyDate, DocumentID
Adobe Creative Suite, Lightroom, Bridge, Capture One, DAM systems
ID3 (Audio Metadata)
The standard for audio file metadata, primarily used in MP3 files. ID3 tags store artist, album, track, and other music-related information.
Title, Artist, Album, Year, Track, Genre, Comment, AlbumArt
MP3, FLAC, OGG, M4A, WAV, AIFF
EXIF vs IPTC: Key Differences
EXIF and IPTC are the two most common metadata standards found in image files. While both store information about an image, they serve different purposes and are used in different contexts.
| Aspect | EXIF | IPTC |
|---|---|---|
| Primary Use | Camera & image technical data | Editorial & publishing metadata |
| Best For | Photography, forensics | News, stock photos, archives |
| Common Tags | Make, Model, ISO, GPS | Headline, Keywords, Copyright |
| File Types | Images (JPEG, RAW, TIFF) | Images, documents, video |
| Format | Binary, app-specific | Standardized text records |
ExifMeta extracts both EXIF and IPTC metadata from your files, displaying them in separate categories so you can easily find the information you need.
