EasyExif

EasyExif is a Python library to easily edit EXIF dates in image and video files, and also file-system times (created/modified time).

Installation

1. Make sure you have Python
2. Download EasyExif
3. Download Phil Harvey's amazing ExifTool: https://exiftool.org/
4. Install prerequisites:

pip install PyExifTool piexif pywin32

Usage

python easyexif.py {to} {from} {filename}

{to} defines which attributes to update (can be multiple):

• c: OS Created-date
• m: OS modified-date
• n: Filename-prefix. Adds a prefix to the filename in this format: YYYYMMDD-HHMMSS~)
• x: EXIF

{from} defines where to take the value to be set:

• c: OS Created-date
• m: OS Modified-date
• n: Filename-prefix. Expects the filename to contain a date prefix in this format: YYYYMMDD-HHMMSS~)
• x: EXIF
• YYYY-MM-DD[THH[:MM[:SS]]] explicit date
• +HH:MM[:SS] add time
• -HH:MM[:SS] reduce time

{filename} can contain wildcards

Examples

1. Set the modified-date from the exif-date:

   python easyexif.py m x *.jpg

2. Set the EXIF-date from the modified-date:

   python easyexif.py x m *.jpg
   

3. Set the EXIF-date and filename-prefix from the modified-date:

   python easyexif.py xn m *.jpg

   In addition to setting the exif-date, this will also prefix the modified-date to the filename using YYYYMMDD-HHMMSS~ format.
   
   

4. Set the EXIF-date and modified-date from the filename:

   python easyexif.py xm n *.jpg

   Expects the filename to have a prefix of YYYYMMDD-HHMMSS~
   
   

5. Set the EXIF-date and modified-date to the specified date:

   python easyexif.py xm 2022-01-01T01:02:03 *.jpg

6. Add time to the EXIF-date and modified-date:

   python easyexif.py xm +01:02:03 *.jpg
   

7. Reduce time from the EXIF-date and modified-date:

   python easyexif.py xm -01:02:03 *.jpg

Caveats

• Only tested on Windows
• {filename} should be a file/files, but not a directory (otherwise it tries to apply changes to the directory itself).
