For photographers who need a fast field workflow, CardRunner helps you get the right images off your camera or memory card quickly so you can stay focused on the action. CardRunner detects connected cameras and cards, searches for photos in the background, and lets you import everything for free! You can upgrade to Pro to pull only protected (locked) or star-rated shots. Once selected photos are copied locally, CardRunner clearly confirms that it’s safe to remove your card and get back to shooting. Your imported collections stay available after relaunch, can be archived for later review, and prevent accidental duplicate imports. Save to your camera roll, share with an editor, client, or friend, or send photos straight to your editor with Photostream. -- KEY FEATURES -- • Automatic Camera Detection — Connect a camera or memory card and CardRunner prepares new photos for import • Free Unlimited Import — Import as many images as you want, free forever • Fast Field Ingest — See how many new images are ready and know when it’s safe to remove your card • Persistent Collections — Review imports later, archive older collections, and avoid duplicate imports • Smart Filtering — Import only protected (locked) or star-rated images (Pro) • RAW Support — Import, save, and share ARW, CR2, CR3, NEF, ORF, PEF, RW2, and more (Pro) • Full Size or Optimized — Save originals or compress for faster transfers on slow connections • Photostream — Stream photos to your editor’s gallery with a simple join code, automatically or when you choose • Pro via Photostream — Photostream-connected users unlock Pro features automatically • Geotagging — Tag imports with your current location so every shot knows where it was delivered (Pro) • Favorites — Mark your best shots and see them on a home screen widget • EXIF Viewer — Camera, lens, ISO, aperture, shutter speed, and more at a glance • iPad Support — Works natively on iPhone and iPad -- BUILT FOR THE FIELD -- Shooting on location with limited connectivity?

Save full-size originals or optimized copies for faster sharing over cellular or limited connectivity while keeping your originals intact. With Photostream, your editor can see photos as soon as you import them. Prefer more control? Turn off automatic uploads and send individual photos when you’re ready. -- FREE + PRO -- Import unlimited images for free. Upgrade to CardRunner Pro for rated-only and protected-only imports, RAW support, geotagging, and additional optimization controls.
