Document tool

Metadata Checker

Upload any file to preview it and see its full metadata: author and creator info, EXIF data, PDF info, an AI-generated content check, and more.

How it works

Drop or choose a file and it is read directly in your browser. General file details always show, plus author and creator info, format-specific metadata such as EXIF for JPEG photos, embedded text for PNGs, document info for PDFs, an AI-generated content check for images and PDFs, and resolution or duration for audio and video. Nothing is uploaded to a server.

Ready. Drop a file or browse to inspect its metadata.
Why this tool

See exactly what's inside your files.

Files carry more information than what you see on screen. Photos embed EXIF data like camera model, exposure, and the date taken. PDFs store an author, title, and producer application. Videos and audio files carry resolution and duration. This tool surfaces all of it instantly, right in your browser.

Nothing is uploaded. The file is read using your browser's own APIs, so it never leaves your device. That makes it safe to check metadata on personal photos or sensitive documents before sharing them elsewhere.

Frequent asks

Metadata, answered.

Is my file uploaded to a server?+

No. Every file is read and inspected entirely in your browser using JavaScript. Nothing is uploaded, so your files stay private.

What file types are supported?+

You can upload any file. Images, PDFs, audio, and video get a live preview plus detailed metadata such as EXIF data, PDF document info, and resolution or duration. Other file types show general details like size, type, and last modified date.

What is EXIF data?+

EXIF data is information a camera or phone embeds in a JPEG photo, such as the camera make and model, date taken, exposure settings, and focal length. This tool reads and displays that data directly from the file.

Can I copy the metadata results?+

Yes. Use the Copy details button to copy all extracted metadata as plain text to your clipboard.

Can this tool tell me if an image was made by AI?+

For images and PDFs, the tool checks embedded metadata for C2PA content credentials and known generator signatures such as DALL-E, Midjourney, Stable Diffusion, and Adobe Firefly. A "Yes" result means a marker was found. A "No indicator found" result means no marker was found, which is not proof the file is authentic, since metadata can be stripped or edited.

Can I see who created a file?+

When present, the Authorship section shows the author, creator tool, camera make and model, and copyright information pulled from EXIF, XMP, or PDF document metadata.
