About
The Metadata Viewer reads the hidden metadata embedded in a file and explains what it means. Drop an image, audio track, video or PDF and it decodes EXIF (camera, lens, exposure), GPS coordinates, XMP and IPTC, MP3 ID3 tags, and the PDF Info dictionary - grouped into readable sections instead of a raw dump.
Its differentiator is AI provenance. It reads the traces AI tools embed in a file - a ComfyUI workflow, an Automatic1111 parameters block, or a C2PA Content Credentials manifest - and turns them into plain-language findings. It reads what a file declares about its origin; it does not analyze pixels, so a clean result means no traces were found, not that an image is definitely not AI.
100% in your browser: parsing runs locally on your device with the File API - no upload, no account needed, nothing stored on a server. Found something you want gone? Hand the file straight to the Metadata Remover without re-uploading.

Each guide focuses on one metadata type and lets you inspect your file on the same page.
Frequently Asked Questions
About reading EXIF, GPS, AI traces and other embedded metadata.
It reads embedded metadata from images (PNG tEXt/iTXt/zTXt chunks, JPEG EXIF/IPTC/XMP, WebP), audio (MP3 ID3v1/ID3v2, FLAC Vorbis comments, M4A tags), video (MP4/MOV container atoms plus GPS) and PDF (Info dictionary and XMP). It groups them into camera/EXIF, GPS, XMP/IPTC, audio tags, PDF info and raw chunks, and highlights anything sensitive.
It detects AI generation traces embedded in the file, not the pixels. If a PNG carries a ComfyUI workflow, an Automatic1111 parameters block, or a C2PA manifest, it reads and explains them. It does not analyze the image itself, so a clean result means no AI metadata was found - it does not prove the image is not AI, because those traces can be stripped.
No. Everything runs in your browser. The file is read locally with the File API and never sent to a server, which is why the tool works offline and shows an "Analyzed locally, nothing uploaded" badge.
AI image tools embed how an image was generated as text inside the PNG. ComfyUI stores the full node graph under a "workflow" key; Automatic1111 stores the prompt, negative prompt, seed, sampler and model under a "parameters" key. This tool surfaces both so you can see (or remove) exactly what a shared image reveals.
C2PA (Content Credentials) is a cryptographic manifest attached to a file that records how it was created or edited, often tagging it as AI-generated or AI-edited. This tool detects the presence of a C2PA manifest. It does not verify the cryptographic signature, so it reports "detected, not verified".
Yes. If a photo or video carries GPS coordinates in its EXIF or container metadata, the tool decodes them to a latitude/longitude and gives you a link to open the location in a map. It does not embed any external map or tracker, so opening the map is your explicit choice.
Yes. Drop multiple files and the tool switches to a triage table that flags which files carry GPS, AI traces or C2PA and how many metadata fields each has. Click any row to drill into the full inspector, export the report as JSON or CSV, or select flagged files and send them to the Metadata Remover.
After analyzing, use the "Remove it with Metadata Remover" link. It hands the already-loaded file (or your selected files from triage) straight to the Metadata Remover without a re-upload, so you can strip GPS, AI workflow and other data in one step.
