QSDC
Easier SD card photo download
Free
QSDC is a fast culling and viewer app for the photos on your SD card — without importing them first.
Plug in a card reader, review on the spot, and download only the shots you want to Photos. It never writes to the card — fully non-destructive.
WHO IT'S FOR
· Photographers who need to cull hundreds of shots quickly after a shoot
· Anyone who wants to check and select high-resolution RAW (RAF, etc.) in the field
· People who'd rather keep their camera roll clean and import only the keepers
KEY FEATURES
· Import-free SD browsing — open the card and view without importing
· Fast culling marks — sort into Keeper / B-cut (maybe) / Reject, and filter by mark
· Photos-like browsing — smooth zoom transition, swipe paging, swipe down to dismiss
· 100% zoom — check focus and detail at native pixels
· Composition guides — rule of thirds, golden ratio, golden triangle (long-press to switch)
· RAW dual-path — fast embedded previews for browsing, full decode for precise checks
· Sort — by capture date, newest or oldest first
· Download keepers only — save just the photos you picked; already-downloaded shots are marked, and duplicates can be skipped
· Metadata — camera, lens, shutter, aperture, ISO, focal length (EXIF)
· Per-card thumbnail cache — set retention and a size cap, with low-space warnings
· Camera-roll grid — adjustable columns, portrait and landscape
· Non-destructive (read-only) — never deletes or alters photos on the card
HIGHLIGHTS
· Light & dark themes, minimal UI that puts photos first (customizable detail background)
· iPhone and iPad, with smooth layout across rotation
· No ads, no sign-up, no network — everything runs on device
Start culling the photos on your card, fast and light, with QSDC.
