Free Metadata Analyzer
Read your file's metadata without uploading it. ExifTool runs in your browser to show available dates, creator details, camera and software tags, location fields and custom properties. Search the results and download the complete collected report.
Your files stay on your computer.
GDF Free Tools analyze files and email headers in your browser on your own computer. Your selected files, pasted headers and extracted results are not uploaded to GDF or an outside analysis service. The page and parser download to your browser; inspection runs locally.
No account or email address is needed to inspect an input or download its report. Reports may contain private information, so review them before sharing.
Using the results in forensic work
Use a working copy for inspection and preserve the original evidence. The report records the inspected input hash, inspection time and tool version so you can document what you examined. Check important findings and the tool’s limits as part of your examination. Metadata and email headers alone do not establish authenticity.
The inspection time comes from your browser’s clock; it is not an independently verified timestamp.
Inspect your file
No uploads. Your file stays on your device. This tool reads metadata in your browser. Your file and metadata are not sent to GDF or an outside service. Optional usage measurement stays off unless you allow Analytics. It sends GDF only the tool name and fixed action labels, such as analysis completed or report prepared. No input, result, filename or visitor identifier is sent. Google and advertising scripts do not load on this page. Use Cookie settings below to change your choice. Clear removes this page's input and results; downloaded reports remain on your device.
Images, PDFs, Office files and other formats ExifTool recognizes. Maximum 20 MiB. The first inspection downloads about 28 MiB of parser files to your browser. Your selected file is not uploaded.

What you can inspect
- Images: available EXIF, GPS, IPTC, XMP, camera MakerNotes, color profiles and file properties.
- PDF and Office documents: readable document properties, custom fields and XMP metadata. These are metadata results, not a document viewer.
- Other recognized formats: ExifTool also reads metadata from many audio, video, camera RAW and other files. Browser limits and the records present in your file determine the results.
Repeated tags retain their group and instance. Readable values appear beside numeric values where they differ. Derived fields and browser-supplied properties are identified separately.
Binary metadata is listed with its size rather than exported as embedded images or attachments. Extraction includes supported embedded metadata. A file may contain few tags, none, unreadable records or more data than this browser tool can process.
How to read the results
Names, dates, software and location fields can be edited. Their presence or absence alone does not establish authorship, a complete editing history, tampering or whether an image was generated by AI.
The browser's filename and last-modified date are separate from embedded metadata. Temporary inspection-environment paths, permissions and timestamps are excluded because they do not describe your original file system.
No digital signature, certificate trust or document authenticity verdict is provided. Password-protected content is not decrypted.
Inputs are limited to 20 MiB. Inspection stops after 15 seconds; extraction and report limits are stated with the results. Download a PDF report or export the collected data as CSV, HTML or JSON. Filtering the on-page display does not filter the downloads. Each export states any limits or omissions.
Metadata extraction uses ExifTool by Phil Harvey, running locally through a WebAssembly port. The report records the actual engine version and extraction options. Engine and license details.
