Online demo: http://piexif-demo.appspot.com/demo

Install

'easy_install':

$ easy_install piexif

or 'pip':

$ pip install piexif

or download .zip, extract it. Put 'piexif' directory into your environment.

Why Choose Piexif

• Pure Python. So, it runs everywhere where Python runs.
• Easy exif manipulations. Read, write, remove...
• Documented. http://piexif.readthedocs.org/en/latest/

How to Use

There are only just five functions.

• load(filename) - Get exif data as dict.
• dump(exif_dict) - Get exif as bytes.
• insert(exif_bytes, filename) - Insert exif into JPEG, or WebP.
• remove(filename) - Remove exif from JPEG, or WebP.
• transplant(filename, filename) - Transplant exif from JPEG to JPEG.

Example

exif_dict = piexif.load("foo1.jpg")
for ifd in ("0th", "Exif", "GPS", "1st"):
    for tag in exif_dict[ifd]:
        print(piexif.TAGS[ifd][tag]["name"], exif_dict[ifd][tag])

With PIL(Pillow)

from PIL import Image
import piexif

im = Image.open(filename)
exif_dict = piexif.load(im.info["exif"])
# process im and exif_dict...
w, h = im.size
exif_dict["0th"][piexif.ImageIFD.XResolution] = (w, 1)
exif_dict["0th"][piexif.ImageIFD.YResolution] = (h, 1)
exif_bytes = piexif.dump(exif_dict)
im.save(new_file, "jpeg", exif=exif_bytes)

Environment

Tested on Python 2.7, 3.5+ and PyPy3. Piexif would run even on IronPython. Piexif is OS independent and can run on Google App Engine.
