How to Free Up Mac Storage: Clean Duplicate Photos & Videos with On-Device AI

Reduce video sizes with quality and resolution controls. Save compressed copies in a separate folder, or replace originals only after the new video passes safety validation. Processing stays on your Mac.

The biggest mistake when cleaning photos is scanning your entire drive at once. When identical photos live in both your Photos library and a synced Dropbox folder, mixed results make it hard to tell which file you should keep.

Scan in this structured order:

• Apple Photos library first: Clean your main library so you know your keepers before inspecting other folders.
• Mac & MacBook folders next: Scan Downloads, Desktop, and old backup folders.
• Synced cloud folders one by one: Clean iCloud Drive, Google Drive, Dropbox, and OneDrive individually to avoid sync conflicts.

Vision AI runs 100% on-device, reading the local directories your cloud apps sync to your Mac without requiring cloud logins.

Exact duplicate photos on Mac share identical image content. Vision AI matches photos by content rather than filename, meaning IMG_4021.jpg and IMG_4021 copy.jpg are correctly grouped even after renaming.

One copy in each group is automatically preserved as the best keeper, protecting you from deleting whole sets by accident. You can filter by date, file size, and format, and bulk-delete exact duplicates to Trash with complete confidence.

Most Mac photo libraries are filled with visually similar shots: consecutive burst takes, resized social media exports, and different framing of the same scene.

On-device Vision AI scores similarity locally on your Mac. Using the similarity slider and side-by-side synchronized zoom, you can compare fine details, pick the sharpest shot, and delete redundant copies quickly.

Out-of-focus and motion-blurred photos are obvious candidates for deletion, but scrolling through thousands of photos to find them is impractical.

Vision AI calculates sharpness ratings on your Mac, ranking the blurriest shots first. Adjustable blur sensitivity lets you cull ruined takes in seconds.

Every Live Photo stores both a high-resolution still image and a 1.5-second video clip that often exceeds the photo in file size.

Converting Live Photos to stills preserves your high-resolution pictures while purging the underlying video clips, freeing gigabytes instantly while keeping album organization and dates intact.

Burst mode can quickly generate 30 frames in a few seconds. Vision AI groups burst frames by capture moment, allowing you to select the best pose or smile and discard the rest.

Shooting in RAW + JPEG doubles your storage consumption. Vision AI displays pairs side by side with respective file sizes, letting you review your archives and remove redundant RAW files for finished shoots.

Video cleanup provides the fastest storage gains:

• Duplicate videos: Exact matches that can be purged in bulk.
• Similar video takes: Compare poster frames to keep the final edited take.
• Largest video files: A ranked list of the heaviest video files taking up space on your Mac.

Retina screenshots on macOS are heavy PNGs that quickly become obsolete. Culling outdated screenshots is a risk-free way to reclaim gigabytes before sorting personal photos.

When cleaning synced iCloud Drive, Google Drive, Dropbox, or OneDrive folders, remember that deletions sync to all devices on that account. Vision AI protects you by always marking a keeper and routing deletions to macOS Trash.

Vision AI never deletes files behind your back:

• Review before delete: You confirm every removal.
• Trash & Recently Deleted: Files move to macOS Trash or the Photos app Recently Deleted folder for a 30-day safety net.
• 100% on-device: All analysis remains strictly local to your Mac.
