EXIF Viewer — Tool Documentation

Read, inspect, and understand all metadata embedded in any image file.

Overview

The ExifInjector EXIF Viewer is a free, browser-based tool that reads and displays every metadata field embedded in image files. It supports all three major metadata standards — EXIF, IPTC, and XMP — and presents them in a clean, organized interface that requires no technical knowledge to interpret.

Unlike command-line tools or desktop applications, the EXIF Viewer works entirely in your browser. Your images are never uploaded to any server — all parsing happens locally on your device.

Key Features

Comprehensive metadata display — reads EXIF, IPTC, XMP, ICC profiles, and Maker Notes
GPS map visualization — plots image location on an interactive map if GPS data is present
Thumbnail extraction — displays the embedded JPEG thumbnail alongside the full image
Raw hex view — for technical users who need to inspect the actual binary data
Export as JSON — download all metadata as a structured JSON file
Batch viewing — inspect multiple images and compare their metadata
Zero upload — all processing is client-side; files never leave your device

🏭 Maker Notes (Proprietary)

Manufacturer-specific data stored in proprietary format. Canon, Nikon, Sony, and other manufacturers store lens correction data, in-camera settings, and focus information here. The viewer decodes and displays these where possible.

GPS Map View

When an image contains GPS coordinates, the viewer displays an interactive map showing the exact location where the photo was taken. Features include:

Satellite and street map toggle
Coordinate display in decimal degrees and DMS format
Copy coordinates button
“Open in Google Maps” link
Direction indicator (if GPSImgDirection is present)

Exporting Metadata

Export as JSON

Click “Export JSON” to download all metadata as a structured file:

Export as CSV

For batch metadata analysis, the viewer can export metadata from multiple images as a CSV spreadsheet.

Privacy Guarantee

The EXIF Viewer processes all files locally in your browser using the Web File API and JavaScript. No image data is transmitted to ExifInjector servers at any point.

You can verify this by opening your browser’s Network DevTools (F12 → Network tab) and watching for any outgoing requests when uploading and viewing an image. You will see none related to your file.

Technical Details

The viewer is built on ExifInjector’s custom JavaScript metadata parser, which implements:

EXIF: Full TIFF/EXIF 2.32 specification support including all standard IFD tags and sub-IFDs
IPTC: IIM (Information Interchange Model) record 2 fields
XMP: Adobe XMP specification with Dublin Core, IPTC extension, and custom namespaces
Maker Notes: Decoded entries for Canon, Nikon, Sony, Fuji, Olympus, Panasonic, and Leica
