About: File Inspector

File Inspector analyzes any file you drop on it and shows everything it can find: size, MIME type, SHA-256 hash, image dimensions and dominant colors, text statistics, and audio or video duration. It also reads embedded metadata such as EXIF, GPS coordinates or author fields, and lets you edit or remove it. Typical uses include checking a download against its published checksum, stripping the location from a photo before posting it, or fixing the tags on an MP3.

Features

  • Computes the SHA-256 hash of any file so you can verify its integrity after a download or transfer.
  • For images: dimensions, megapixels, aspect ratio, transparency and a palette of dominant colors as hex codes.
  • For text files: detected encoding, line and blank line counts, word count, and characters with or without spaces.
  • Reads metadata from images, audio, video and PDF files, with a map link when GPS coordinates are present.
  • Edit, add or remove metadata fields, GPS data, color profiles or MP3 cover art, then download an updated copy.

How to use it

  1. Drop a file onto the page or click to choose one.
  2. Check the Details tab for basic info and the SHA-256 hash, then the Analysis tab for type-specific data.
  3. Open the Metadata tab to read, edit or strip tags, and save to download the modified copy.
  4. Copy the full report as JSON if you need it elsewhere.

Questions about usage

No. Analysis, SHA-256 hashing and metadata editing all happen in your browser. The metadata engine (ExifTool compiled to WebAssembly, about 25 MB) is downloaded the first time you open the Metadata tab and then processes the file locally.

Open the Metadata tab and click "Remove location" to drop only the GPS data, or "Remove all" to strip every metadata field. A cleaned copy of the file is downloaded and the original stays untouched.

Every file gets basic info and a SHA-256 hash. Detailed analysis covers images, text files (txt, md, json, csv, source code and more), audio and video. Metadata can be read and edited for images, audio, video and PDF, though PDFs are limited to their standard document fields.
