imagesize
This module analyzes JPEG/JPEG 2000/PNG/GIF/TIFF/SVG/Netpbm/WebP image headers and returns image size or DIP.
import imagesize
width, height = imagesize.get("test.png")
print(width, height)
width, height = imagesize.getDPI("test.png")
print(width, height)This module is a pure Python module. You can use file like object like file or something like io.BytesIO.
API
imagesize.get(filepath)Returns image size (width, height).
imagesize.getDPI(filepath)Returns image DPI (width, height).
Benchmark
It only parses headers, and ignores pixel data. So it is much faster than Pillow.
| module | result |
|---|---|
| imagesize (pure Python) | 1.077 seconds per 100 000 times |
| Pillow | 10.569 seconds per 100 000 times |
I tested on MacBookPro (2014/Core i7) with 125kB PNG files.
Development
Run test with the following command:
