Prepare once. Keep moving.
On Mac, turn a folder of RAW photographs into lightweight JPEG previews. Review the shoot without developing a RAW file at every key press.
Made for photographers · Preparing for release
Make room
for the best.
Less waiting. More seeing. Work through your shoot with lightweight previews, a clear view of the photograph, and your fingers on the keys.
Free core app. No advertising. Your eye makes the decisions.
SpeedCull
Find the ones worth keeping.
The photograph comes first
A calmer way through a big shoot.
Nothing between you and the image.
Use the grid to find a frame, Loupe to take a closer look, and a clean full-screen view when you want the photograph to fill your attention.
Keep your rhythm.
Arrow keys to move. 0–5 to rate. Pick, reject and compare with shortcuts. Progressively narrow a shoot to your strongest photographs.
From a full card to a shortlist
Your next edit starts here.
Open your shoot
Scan a RAW folder on Mac, or return to your recent work.
Build previews
Choose the detail you need. Generated previews are separate from your originals.
Make the selection
Rate, flag and compare. Your decisions stay in the SpeedCull catalogue.
Continue your edit
Send star ratings to Lightroom Classic with the optional plug-in, or write XMP sidecars for a compatible photo app.
Choose one export route in the Sync tab. The Lightroom ratings-only plug-in does not require an XMP sync first. Read the sync guide.
A closer look
Give the strongest frame its moment.
Compare similar frames side by side in Keeper Mode. Zoom into a generated preview at its actual pixel size, or use the Mac RAW module to inspect a focus crop when supported.
Camera autofocus metadata and RAW compatibility vary by camera and file. SpeedCull is a selection tool, not a RAW editor or a replacement for your backups.
Your work stays yours
Pick up where you left off.
Return to a recent shoot with your previews and ratings ready. Work locally on your Mac, then send your selections to your next editing app when you choose.
Clear generated previews when you need the space. Your ratings, catalogue, RAW originals and XMP sidecars stay intact.
Release status
Free. Focused. Coming soon.
SpeedCull for Mac is preparing for TestFlight and the Mac App Store. A public download or beta invitation is not available yet.
