This module analyzes JPEG/JPEG 2000/PNG/GIF/TIFF image headers and returns image size.

import imagesize

width, height = imagesize.get("test.png")
print(width, height)

This module is a pure Python module.

• imagesize.get(filepath)

  Returns image size (width, height).

It only parses headers, and ignores pixel data. So it is much faster than Pillow.

I tested on MacBookPro (2014/Core i7) with 125kB PNG files.

• TIFF

  It can returns only first picture's size because of restriction of API design.

  It supports only small TIFF file. BigTIFF support is not implemented.

Run test with the following command:

python -m unittestt
