01 · GETTING STARTED
Your first compression, step by step
Read the welcome screen
Tap Get Started after reviewing the app’s three core areas: local browsing, compression, and history.
Choose Photo Library access
Full access lets you browse all available local videos. Limited access shows only the videos you select. The App does not request or download iCloud-only media.
Pick one video or select a batch
Tap a row to inspect a single video, or tap Select to choose several local videos for batch compression. Sort by date, size, duration, or resolution when needed.
Review the source
Check resolution, codec, frame rate, bitrate, duration, size, and HDR status before changing the output settings.
Set a conservative target
Choose a resolution and bitrate, leave Skip If Larger enabled, and keep the original for your first test.
Compress, compare, then decide
Wait for the progress screen to finish. Review the result in Photos before deleting any original video.
02 · SETTINGS
What each control means
Original, 4K, 1080p, 720p, or 480p
Lower resolutions usually save more space but reduce visible detail. Start with 1080p for general sharing, or keep Original when resolution matters.
0.5–50 Mbps
Bitrate has the strongest effect on size and quality. Lower it gradually; use the estimate as guidance because complex scenes may produce a different final size.
HEVC (H.265) or H.264
HEVC is generally more space-efficient on modern Apple devices. H.264 offers wider compatibility with older devices and software.
Original, 60, 30, or 24 fps
Keeping the original frame rate is the safest default, especially for high-motion footage.
Recommended: On
The result is not saved when it would be larger than the source. This helps avoid wasting storage on videos that are already efficient.
Useful, not exact
The estimate combines target video bitrate and audio bitrate. Actual VBR output varies with duration and visual complexity.
03 · ORIGINAL VIDEO
Keep first. Delete only after review.
Keep
Saves the compressed result as a new video and leaves the source untouched. Use this for your first compression and any important recording.
Replace
Applies a non-destructive Photos edit to the same asset. Apple Photos may retain original data so the edit can be reverted; do not rely on this option alone to free storage.
Delete
Saves a new compressed copy, then asks iOS to delete the original. Confirm only after checking playback, quality, audio, orientation, and the saved file.
04 · HISTORY
Track results without touching your media
History stores local technical details about completed compressions so you can compare sizes and locate the original and compressed assets. Clearing History removes only those local records; it does not delete videos from Photos.
SAFE FIRST RUN
A sensible starting point
- Choose a short, non-critical local video.
- Set 1080p, HEVC, Original frame rate, and a moderate bitrate.
- Leave Skip If Larger on and Original Video set to Keep.
- Play the saved result in Photos and check video, audio, orientation, and color.
- Only then decide whether the original should be deleted.
