Image Metadata Viewer
Inspect EXIF tags, camera settings, GPS coordinates, PNG chunks, and binary container metadata without file uploads.
Images are read directly into browser memory using HTML5 File APIs. No data leaves your machine.

In-Browser Binary Image Metadata Inspection
The Image Metadata Viewer scans the binary header segments of digital photos and illustrations to extract embedded camera settings, EXIF APP1 tags, TIFF Image File Directories (IFDs), GPS geotag coordinates, PNG pHYs physical resolution chunks, and WebP VP8X extended header flags directly within your web browser. By parsing binary structures on the client side, this utility bypasses the need for remote cloud processing, keeping your media secure and completely local.
Digital images contain complex binary containers where metadata is organized in precise offsets. JPEG files employ APP marker segments (such as APP1 for EXIF and TIFF headers), while formats like PNG rely on a sequence of discrete critical and ancillary chunks (such as IHDR, pHYs, and tEXt). This viewer reads the raw file bytes using low-level JavaScript DataView objects to decode these structured records into human-readable tables, allowing you to audit file history, capture parameters, and device parameters.
Because metadata is optional and often discarded during web optimization, this tool includes robust diagnostic logging to explain missing headers without implying that every image contains EXIF blocks. If your inspection reveals sensitive exposure data, capture timestamps, or location geotags that you want to scrub before sharing, you can transition directly to our EXIF Metadata Stripper to permanently purge these structures from your images.
Core Tool Capabilities
- EXIF & TIFF Binary Parsing: Decodes TIFF header structures and Image File Directories (IFDs) within the JPEG APP1 segment, extracting camera manufacturer, camera model, lens specifications, software tags, and original capture timestamps.
- Camera Exposure Diagnostics: Isolates vital camera sensor settings including ISO speed ratings, f-number aperture values, shutter speed exposure times, focal lengths, metering modes, and flash firing states for detailed photography audits.
- GPS Geotag Extraction: Decodes binary GPS IFD coordinates (rational coordinate arrays representing degrees, minutes, and seconds) into standard decimal latitude, longitude, and altitude values with direct map viewing links.
- PNG, WebP & GIF Chunk Scans: Scans PNG ancillary chunks (pHYs for physical DPI, tEXt/iTXt for textual descriptors), WebP container chunks (VP8X features, EXIF, ICCP), and GIF logical screen descriptors to analyze file properties.
- JSON Report Compilation: Aggregates parsed key-value structures from all inspected files into a unified JSON report. This structured JSON document can be exported directly to your device for archiving or compliance documentation.
- Privacy-Preserving Audit Workflow: Analyzes binary byte sequences entirely in browser memory. No network connections are initiated to upload photo files, ensuring your camera, GPS, and device information remains private.

Click on any file in the loaded list to parse its headers. Switch between files in real time to compare metadata structures side by side.
Filter and Audit Metadata Sections
Browse categorized tabs representing File details, Dimensions, Camera settings, GPS coordinates, and raw container chunk tables.
Export Structured Metadata
Download a detailed metadata report in JSON format for your records, or utilize the EXIF Metadata Stripper if you discover sensitive tags.
Practical Real-World Use Cases
Photography Audit & Asset QA
Photographers and catalog designers inspecting exposure settings, lens configurations, and capture timestamps across a batch of photos to verify shooting consistency.
Privacy Audit Prior to Public Sharing
Social media managers, developers, and privacy-conscious users auditing photos for embedded GPS coordinates and device identifiers before uploading them.
Web Graphics Optimization & Debugging
Web developers inspecting PNG pHYs density markers to audit DPI settings, checking color spaces, and verifying WebP container features.
Security Research & Forensic Analysis
Digital forensic investigators and security analysts reviewing image headers to verify software editing history, camera details, and embedded timestamps.
Frequently Asked Questions
- Are my photos uploaded to an external server to view metadata?
- No. All binary header scans, TIFF directory decoding, and EXIF tag extractions occur locally inside your web browser. No image data or parsed metadata is transmitted over the network.
- Does every digital image contain EXIF metadata?
- No. EXIF metadata is optional. While digital cameras and smartphones write detailed metadata when capturing photos, graphics created in design tools, vector SVGs, and images processed by social media platforms or chat applications typically have metadata stripped.
- Can this tool extract GPS coordinates from any photo?
- Only if the capturing device (smartphone or GPS-enabled camera) had location services active during capture and the file was not subsequent stripped. If GPS IFD tags exist, this tool decodes the rational numbers into precise decimal coordinates.
- What should I do if I find sensitive camera or GPS metadata?
- If inspection reveals metadata you want to remove, use the EXIF Metadata Stripper to remove supported EXIF metadata from an image. It will rebuild your file with clean headers before you publish it online.
- Why does the tool show some values as 'Unknown Tag'?
- Some camera manufacturers use proprietary binary structures called MakerNotes inside the EXIF block. Since these MakerNotes use non-standardized private schemas, the viewer displays them as unknown or unresolved raw values.
