How to Restore Essential Exif Data to Stripped Images for Optimal Web Performance?

Adding Exif Data to Images

When dealing with a high volume of user-uploaded photos, it becomes crucial to optimize file sizes to ensure smooth and efficient website performance. Stripping exif data from images is a common practice to reduce file size. However, in certain scenarios, there may be a need to re-introduce basic exif data, such as copyright information, to the modified images.

One highly effective solution is to utilize the Exiftool utility. Exiftool provides a comprehensive set of commands to read, write, and edit exif data within images. For instance, to add a copyright notice to an image named "image.jpg," you can use the following command:

exiftool -Copyright="Initrode" image.jpg

Exiftool seamlessly integrates with most image editing applications, making it a versatile tool. If you prefer a PHP-based approach, consider using the PHP Exif library. This library offers a wide range of functions to manipulate exif data, including the ability to add, modify, or remove specific tags.
