What Is MediaPeek and What Does It Do?

Updated

MediaPeek is a browser-based tool that inspects media metadata from a URL and shows it in a structured interface. It fits when you need to identify codecs, formats, or badge-level details (resolution, HDR, audio type) of a file you can reach by link — including large files — without downloading the whole thing. It accepts HTTP/HTTPS URLs and public Google Drive files and folders, and it can look inside ZIP and TAR archives.

What it does

MediaPeek covers four tasks, from fetching to sharing:

  • Partial fetching. It reads only the bytes needed from a URL using byte-range HTTP requests, so no full download is required even for large files. Requests are edge-processed near the user.
  • Archive support. It looks inside ZIP (Stored, DEFLATE) and TAR (standard + @LongLink) archives without extracting the full file, and keeps the archive name visible so you retain archive → filename context.
  • Multiple exports. Metadata can be exported as Object JSON, Text, HTML, or XML — readable for humans or machine-parseable for pipelines.
  • Encrypted sharing. Results can be shared through encrypted links. MediaPeek states it does not store the content, and the key stays in the URL (end-to-end encryption via PrivateBin).

How the metadata engine works

Analysis runs in the browser through mediainfo.js v0.3.7, a WebAssembly port of MediaInfoLib (v 25.10, © 2002–2026 MediaArea.net SARL). Because parsing happens in WebAssembly, the inspection is based on the same MediaInfo library widely used for media file identification, rather than a proprietary parser.

A practical example: if you have a link to a multi-gigabyte video and want to confirm whether it is HDR10+ with a lossless audio track, MediaPeek fetches the header and relevant byte ranges, parses them with mediainfo.js, and returns the metadata — you never pull the full file.

Format badges and attribution

Badge assets for consistent media labeling come from Apple TV (SD, HD, 4K, HDR, HDR10+, and related video badges) and Apple Music (Lossless, Hi-Res Lossless, Apple Digital Master, Spatial Audio, AAC). Third-party marks remain the property of their owners and are referenced for identification only; the site lists notices for Dolby, IMAX, DTS, HDR10+, and AV1.

Who it suits

Your need Does MediaPeek fit?
Check codec/resolution/HDR/audio of a file behind a URL Yes — core use case
Inspect a large file without downloading it Yes — byte-range fetching
Look inside a ZIP or TAR without extracting Yes — archive support
Feed metadata into a script or workflow Yes — JSON/XML/HTML/Text export
Share results without exposing content Yes — encrypted links, key in URL
Inspect a private, non-public Google Drive file Not indicated — support is described for public files and folders

Practical notes

  • Open source. MediaPeek is built in public and maintained on GitHub, where you can review issues, track releases, and follow development.
  • No pricing information is provided on the site, so cost or account requirements are not established here.
  • Privacy model. Content is not stored by MediaPeek, but the sharing key travels in the URL — treat shared links as sensitive.

To try it, open the app from the MediaPeek homepage and paste a supported URL.
