exif-date-infer

Adds Exif tag DateTimeOriginal to an image using a date inferred from the filename, if the file does not have an exif date entry already. Useful for adding back Exif dates to images received from messengers like WhatsApp and Facebook Messenger before importing to your photo library.

Currently only supports WhatsApp and Facebook Messenger image filenames.

Usage

    exif-date-infer /path/to/your/images [--overwrite] [--force]

• --overwrite will write the exif data back into your current image file, where as the default behavior is to create a new file with the _date_inferred suffix added to the original filename.
• --force will force writing of inferred date even if exif already exists in the original image.
