How to Scan Multiple Photos at Once on a Mac

✦

By Spencer Baker, founder of Timeline Scan · Last updated: October 2026

Quick answer

To scan multiple photos at once on a Mac, lay four to six prints on the flatbed, scan once, and let photo-splitting software save them into separate files. The free FrontBack Scanner also straightens each one, turns it upright and pairs every back with its front.

The Method: A Bedful Per Pass, Not a Photo Per Scan

✦

One scan

Four files

  • A family of four at the edge of the surfscan_0001.jpg
  • Two parents and a young boy at a mountain picnicscan_0002.jpg
  • A family of six on the front steps of a house, now uprightscan_0003.jpg
  • A large family around a dinner tablescan_0004.jpg
One pass, four separate files: cropped, straightened and turned upright.

  1. Lay Four to Six Photos on the Glass

    Any flatbed works, even an all-in-one printer’s. Leave a finger’s width between prints; four 4×6 prints fit most letter-size beds.

  2. Preview, and Let the Software Find Each Photo

    A preview pass detects each print. Some tools do it automatically; some make you draw every box.

  3. Scan Once: Get One File Per Photo

    One pass saves each photo as its own cropped, straightened file. Four at a time, a 400-photo box takes an afternoon.

  4. Flip the Pile and Scan the Backs

    Flip each print where it lies and scan again. Almost no software pairs the backs with their fronts.

    Why scan the backs?

    Scanned backs are what let a service like Timeline Scan put every photo in its real year automatically. See our scanning best practices for the full checklist.

Watch the orientation. Most software saves a sideways print sideways. Pick one that turns each print upright for you.

The Mac Software That Can Split a Bedful, Compared

We build one of these, so judge accordingly: the table only lists what each tool does.

Splitting a bedful on a Mac
SoftwareSplits a bedfulGood to knowPrice
FrontBack ScannerAutomatically, even tilted, nearly touching or white-bordered printsTurns photos upright and names them; the only one that pairs backs with fronts. macOS 14+Free (ours)
Image CaptureWith “Detect separate items” on, “Use document feeder” offDocument-oriented: struggles with white-bordered prints and photos lying close; no orientation fix; generic file namesFree, built into every Mac
Epson Scan 2 / vendor appsEpson’s thumbnail mode, reasonably well on its own hardwareQuality varies by vendor; orientation usually left to you; none handle backsFree with Epson, Canon or HP scanners
VueScanMulti-crop exists, but photo batches aren’t its focusBest known for keeping orphaned scanners alive (5,000+ models) and for film and slides; famously dense interfacePaid, with a watermarked trial
SnipTagBatch-crops the composite after you scan it with something elseA Mac app; two-app workflow: scan with Image Capture, then split in SnipTag; adds metadata captionsPaid
Photomyne (phone)Not a scanner app: photographs prints with your phone camera and splits themFast for casual sharing; camera captures can’t match flatbed quality for archiving; glossy prints reflect glareSubscription

The honest summary: with a Mac and any flatbed, FrontBack Scanner is free and does the whole job. No install? Image Capture’s “Detect separate items” is serviceable for photos with clear edges; fix crops and orientation by hand.

What About Photo Albums and Fragile Prints?

✦
  • Photos glued into albums

    Scan the whole page instead. Don’t peel them out.

  • Fragile or curled prints

    If a print can’t lie flat, a bedful at a time won’t work.

  • A box too big for a weekend

    Our drop-off scanning service in Lehi, Utah does fronts, backs, dating, and organizing from $0.25 per photo.

Whichever software you use, scan at 600 DPI as JPG (best settings), then see what to do after scanning.

Once the dates are fixed, Family Library keeps the scans in one timeline for $39 a year or a small monthly fee.
