Does Digital Format Matter in Photo and Video Preservation?

All forms of physical media change over time. Whether it’s photos, video tapes, or cassette tapes, being exposed to the elements will erode their quality. CDs and DVDs change over time, too, but the changes tend to be less gradual. One day your music will play, and the next day it just…won’t.

Digital storage will keep your things preserved, but can they still change over time? More importantly, does HOW they’re digitally stored matter?

The answer to both questions is a resounding YES!

Digital files can change over time, because technology changes over time. How we save, access, and view files today is very different than it was even 10 years ago. We call that the file format, and it does not stay the same.

For example, most people who grew up with computers have heard of the JPEG image format, where your file name ends with .jpg or .jpeg. This format was created FORTY YEARS AGO, in 1986! It was designed to be a standard to compress photos so they could be sent over the early internet, which was very slow. Because it was designed for compression, not detail, JPEG format photos do change as they’re opened, edited, and saved repeatedly. For digital storage purposes, more modern formats such as PNG are preferred, as none of the information is compressed, so the format is without loss.

You also have different digital video formats to choose from. Unlike photos, videos didn’t have a standard format early on, so there were a bunch of different incompatible types (QuickTime Player and RealPlayer were two of the popular early versions).

The two most popular video formats now are MP4 and MOV. MP4 videos are universally compatible, meaning they can be played on any modern device, but they do compress video files, resulting in some information being lost. This typically includes things that are not noticeable to human eyes and ears and leads to MP4 being the standard of convenience.

For strict preservation, MOV formats are the way to go. They are not always compatible with every device, and file sizes will be larger because no data is lost during compression. In both formats, once your video is saved, it is saved indefinitely. They won’t change over time unless you edit them, or the device they’re being stored on fails.

Choosing the right format isn’t just a technical decision – it’s what determines how well your memories will hold up over time.  The goal isn’t simply to digitize: it’s to do so in a way that provides accessibility, longevity, and quality.  The right formats, paired with secure digital storage, ensure that your photos and videos will be just as meaningful years from now as they are today.  Not sure where to start?  That’s where we come in.
