Printed photos naturally fade, discolor, and become damaged over time, making it increasingly difficult to preserve precious memories in their original form. Scanning your photos is one of the most effective ways to protect them, but choosing the right scanning resolution is just as important as the scanner itself. A DPI setting that's too low may lose fine details, while one that's too high creates unnecessarily large files without noticeable improvements. Whether you're digitizing family albums, restoring old photographs, or building a long-term digital archive, understanding the best DPI for different photo types and purposes will help you achieve the ideal balance between image quality, storage space, and future usability. Read our complete guide to discover the best DPI for scanning photos and learn which resolution is right for your specific needs.
