RAW Keeper

RAW Keeper cleans up the RAW files filling your storage — and leaves every favorite photo alone. For everyone who shoots RAW+JPEG with a camera and keeps their pictures in Apple Photos. RAW Keeper also shrinks large videos and slims down Live Photos — only if you want it to. WHY RAW KEEPER • 100% on your iPhone, iPad and Mac — no server, no upload, no account • No subscription, no running costs — buy once, Family Sharing included • No data collection, no trackers — your photos stay your photos WHO IT’S FOR Your camera saves RAW+JPEG (or RAW+HEIF) and you import both into Apple Photos? Then every picture is there twice — and the RAW typically takes 20–30 MB per photo. RAW Keeper works with the RAW formats Apple Photos reads, such as RAF (Fujifilm), ARW (Sony), CR3 (Canon), NEF (Nikon) and DNG. ProRAW photos without a JPEG next to them are handled like pairs: in the “Keep the picture” mode, favorites stay ProRAW and the rest becomes HEIC. If you only shoot with your iPhone and without ProRAW, you usually have no RAW pairs — then the section on videos and Live Photos is for you. AFTER EVERY SHOOT Mark your favorites, tap “New since …”, done. RAW Keeper finds the new RAW+JPEG pairs since your last search — in seconds instead of hours. YOU DECIDE WHAT STAYS Keep the picture and remove the RAW (saves the most; the picture is re-saved once at 90% quality) — or keep the RAW and remove the JPEG (lossless, saves a bit less). Favorites always keep both. SAFE BY DESIGN Before/after comparison for every photo. Every change is re-checked immediately beforehand. Originals stay in “Recently Deleted” for 30 days. Shared Library: the replacement lands in your personal library, in the album “RAW Keeper – Converted” (videos: “– Compressed”) — from there it can be moved back to the Shared Library. NO CAMERA? VIDEOS AND LIVE PHOTOS Large, non-favorite videos are re-saved efficiently as HEVC — only if the result is truly smaller. RAW Keeper also finds exact duplicates and accidental clips under 2 seconds; one copy of each duplicate always stays. And if you like, turn Live Photos into regular photos: the picture stays with HDR, portrait depth, date, location and albums, only the short motion goes — usually around 2 MB per photo. Both only when you explicitly choose them. TRY FREE — UNLOCK ONCE Scanning, savings analysis, previews and single-item tests are free. The full version unlocks unlimited clean-up — on iPhone, iPad and Mac.

Verdict
The clearest difference is in-app purchases: Seestar at none against RAW Keeper's 1. Seestar also leads on iOS requirement (13.0 vs 17.0). RAW Keeper's advantage is update cadence (every 5 days vs monthly). On price, ads and device support there is nothing between them.
