TIFF Metadata and Tag Viewer

Drop in a TIFF (.tif or .tiff) to read what the file header and first image directory contain: little or big-endian byte order, exact pixel dimensions, the compression scheme, photometric interpretation, resolution in DPI, and any camera make, model, software, or capture-date tags. The file is parsed entirely in your browser and never leaves your device.

How to view TIFF metadata

  1. Drag a .tif or .tiff file onto the box, or click browse to pick one.
  2. Read the byte order, dimensions, compression, and tag report shown instantly.
  3. Check the camera and resolution rows to see how the file was produced.

Examples

A scanned document

scan.tiff (a 300 DPI scan)
Big-endian, 2480 x 3508, LZW, BlackIsZero, 300 DPI

Frequently asked questions

Is my TIFF uploaded anywhere?

No. The file is read and parsed entirely in your browser using JavaScript. Nothing is sent to a server, so even confidential scans and originals stay on your device.

How does it read the metadata?

TIFF files start with a small header that records the byte order and points to an image file directory (IFD) of tagged fields. The tool reads that header in your browser and decodes the IFD0 tags for dimensions, compression, photometric type, resolution, and camera details.

What does byte order mean?

TIFF can store numbers little-endian (marked II, common on Windows and many cameras) or big-endian (marked MM, used by some scanners and Mac tools). The viewer detects which one your file uses and reads every value accordingly.

Which compression types are recognized?

It names the common schemes including None, LZW, JPEG, Deflate, PackBits, and the CCITT fax modes. Any unrecognized code is shown with its raw numeric value so nothing is hidden.

Why are some fields blank?

TIFF tags are optional. A file only shows a camera make, model, software name, or DateTime if the program that wrote it stored those tags. Blank rows simply mean that tag was not present in IFD0.
