How to Digitize Old Photos: Scanners, Phone Apps & Settings

Shoeboxes and old albums hold photos that exist nowhere else. Prints fade, albums with sticky pages yellow, and a single flood or move can lose decades. Digitizing them protects the images and makes them easy to share with family, print again, or use in a slideshow.

The job is less about the scanner than about having a system. This guide covers choosing a method, the settings that matter, and how to name and back up the scans so you never have to do it twice.

Four ways to digitize old photos

Method	Best for	Strengths	Drawbacks
Flatbed scanner	Prints of any size, the best all-round choice	Sharp, even light, no glare, true resolution	Slow for thousands of prints unless you scan several at once
Phone scanning app	A few hundred prints, quick projects, prints stuck in albums	Free or cheap, fast, already in your pocket	Lower detail, risk of glare and keystone distortion
Camera on a copy stand	Large batches, prints in fragile albums, slides and negatives with a light source	Very fast once set up, high quality with a good lens	Needs a camera, lighting and some practice
Scanning service	Large boxes when time matters more than cost	No equipment or time needed, good services correct color	Originals leave your hands; cost per photo adds up

For most families, a flatbed scanner is the right answer: an ordinary home all-in-one printer with a scanner lid is good enough for prints. A phone app is fine for a first pass, for prints you cannot remove from an album, or to share a photo quickly. Scan your most precious photos on the best equipment you can reach, even if the rest go through a faster route.

Prepare the prints

Sort before you scan. Group photos by event, decade or family branch in labeled envelopes. Scanning in sorted batches makes naming far easier later. Set aside duplicates and blurry shots; you do not need to scan everything.
Handle gently. Hold prints by the edges with clean, dry hands, or wear nitrile gloves. Avoid touching the image surface.
Remove dust, not dirt. Brush prints and the scanner glass with a soft, clean brush or a microfiber cloth. Do not use water, sprays or wipes on photographs.
Leave stuck photos in place. Prints in old self-adhesive (“magnetic”) albums can tear if pulled. Scan the whole page with the lid open or photograph it, and crop each photo afterwards.
Read the backs. Many prints have names, dates or a lab’s date stamp on the back. Scan the back too when it has writing, or note it as you go.

Scanner settings: resolution and file type

Resolution is measured in pixels per inch (PPI, often labeled DPI on scanners). Higher numbers capture more detail from the same print, up to the limit of what the print actually holds.

Original	Scan at	Why
4×6 and 5×7 prints	600 PPI	Enough to reprint at double the size and to crop
Small prints, wallets, 3.5×5	1,200 PPI	Small originals need more pixels to be useful
8×10 and larger prints	300–400 PPI	Already big; higher settings mostly add file size
Documents, letters, recipe cards	300–400 PPI	Plenty for reading and reprinting text
35 mm slides and negatives	2,400–4,000 PPI	The frame is tiny, so it needs much higher resolution

A 4×6 print scanned at 600 PPI gives a 2,400 × 3,600 pixel file, enough to reprint at 8×12. Our print size calculator shows exactly how large any scan can print.

Scan in color, even for black-and-white prints. Old monochrome photos have warm or cool tones that color scanning keeps, and you can convert to grayscale later.
Save a master copy as TIFF or PNG if your scanner offers it. These lossless formats do not lose quality when edited and saved again. Save a high-quality JPEG as well for sharing; most people never notice the difference.
Turn off automatic “enhancement” such as heavy sharpening or dust removal for the masters if the results look artificial. You can always edit a copy.
Scan several prints at once with a small gap between them, then crop. Many scanner programs can split them automatically.

Scanning with a phone

Phone scanning apps are much better than taking an ordinary photo of a print. They find the edges, correct the perspective, and some take several shots from different angles and combine them to remove glare from glossy prints.

Work in bright, indirect daylight near a window. Turn off the flash.
Lay the print on a dark, matte surface so the app finds the edges.
Hold the phone parallel to the print, directly above it, to avoid a trapezoid shape.
Check the export settings and choose the highest quality or original size.
Use the phone for speed and reach, then rescan the photos that matter most on a flatbed.

Slides and negatives

Slides and negatives often hold more detail than the prints made from them, but they are tiny, so they need a different setup. The options are a dedicated film scanner, a flatbed scanner with a transparency adapter in the lid, or a digital camera with a macro lens photographing the film on an even light source such as a light pad. Scan 35 mm film at 2,400 PPI or more. Negatives also need inverting and color correction, which film scanner software usually does for you.

If you have hundreds of slides and no equipment, this is where a scanning service often makes the most sense. Send a small batch first and check the results before sending the rest.

Name, date and caption the scans

A folder of files called scan0001.jpg is barely better than the shoebox. Spend the time now, while you have the prints and the people who remember them.

Name files by date first, so they sort in order: 1978-07_beach-trip_01.jpg. Use 1978-xx or 197x when you only know the year or decade.
Set the photo’s date. Scans carry the date you scanned them, so photo apps put a 1978 picture in this year. Most photo apps let you edit the date and time of a photo; fix it for each batch.
Write captions while people are alive to tell you. Sit with older relatives and go through the scans together on a tablet. Record names, places and stories, even as a voice memo.

Our guide to organizing photos has a full folder structure that keeps originals, scans and edited copies apart, and the caption guide shows how to write captions that bring the memory back.

Back up and share

Digitizing only protects the photos if the files are safe. Follow the 3-2-1 rule: three copies, on two different kinds of storage, with one kept somewhere else, such as a cloud backup or a drive at a relative’s house.

Then put the photos to use. Share a folder with the family and ask everyone to add names. Make a slideshow for the next reunion; the slideshow calculator works out how many photos fit. Print a then-and-now pair with the photo merger, or add a classic white border with the photo border tool. If you want to go further, our guide to animating old photos covers doing it gently, and memorial slideshow ideas helps when the scans are for a service.

Keep the original prints after scanning. Store them flat in acid-free boxes or sleeves, in a cool, dry room rather than an attic or basement.
