Video Slim: Compress Videos

Verify exact duplicate videos on device, choose what to keep, and clean one group at a time for free. No automatic iCloud downloads or deletion choices.

Running out of space on your iPhone? Video Slim helps you find large videos, safely review verified exact duplicates, and create smaller copies with clear quality options.

The duplicate scanner verifies complete local, unedited video resources on device with SHA-256 and matching byte counts. It never downloads iCloud-only videos automatically and never preselects a video for deletion. Compare each verified group, choose the one video to keep, confirm through the system Photos prompt, and let Video Slim reconcile the result afterward.

Sort videos by size, date, or duration. Choose from three understandable quality presets, preview a video, optionally trim its start and end, and review an estimated output size before compression. Video Slim processes everything on your device and never uploads videos to a developer-operated server.

Key features:

• Verify byte-identical local, unedited videos on device
• Compare the reason, size, resolution, and duration before choosing what to keep
• Review and clean one duplicate group at a time for free
• Find large videos in your photo library
• Sort by size, newest, or longest
• Filter by compression candidates, 100 MB or more, 4K or higher, or local availability
• Compare still previews after untrimmed compression and play the saved copy
• Choose High Quality, Standard, or YouTube & Sharing presets
• Preview estimated output size and savings
• Trim the start and end before compression
• Share a saved copy through the standard iOS share sheet
• Build a Smart Batch Plan with up to 20 recommended videos
• Review total estimated savings before purchasing Pro
• Process Pro batches one video at a time
• Track measured space savings on device
• View iCloud download progress and cancel safely
• Verify the compressed copy before saving
• Keep every original unless you explicitly choose deletion
• No account, ads, tracking, or analytics SDKs

Single-video compression and one-group-at-a-time exact duplicate cleanup are free and unlimited. Creating a Smart Batch Plan and reviewing its estimated savings are also free. The one-time Video Slim Pro purchase unlocks batch compression for 2–20 selected videos. There is no subscription or automatic renewal.

Important:

• Edited and iCloud-only videos are excluded from verified exact duplicate results.
• Results vary based on the source format, content, and selected quality.
• Downloading videos stored only in iCloud Photos for compression requires a network connection.
• Deleting a video also affects devices using the same Apple Account with iCloud Photos.
• Storage may not be reclaimed immediately while a video remains in Recently Deleted in Photos.
