SlimByte: Phone Storage Saver
Keep quality. Take less space.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Out of iPhone storage? Auto-Optimize shrinks each video with one tap — see exactly how much space you'll save before you commit to the convert.
Your videos eat your phone storage. SlimByte gives it back.
The Apple way — simple controls, the right options, nothing in the
way. Pick videos, choose target, hit Convert. Typical iPhone
recordings drop 70–90% in size with the quality you see kept intact.
SMART COMPRESSION
• Reduce 4K to 1080p, 720p, or any preset — or let Auto-Optimize
pick per video
• HEVC, H.264, MP4, MOV — work with what your library already uses
• Custom bitrate control for finer-grained quality vs. size
• Adjust frame rate independently (60fps → 30fps saves real space)
• HDR → SDR conversion for sharing-friendly compatibility
• Batch convert dozens of videos in one queue
BUILT FOR iOS
• Native iOS 26 design — Liquid Glass throughout
• Background conversion that survives device lock — start a batch,
lock your phone, come back to finished files
• Live Activity on the Lock Screen tracks per-video progress
• Saved files keep original creation date, modification date, and
location metadata — they sit naturally next to originals in your
Photos library
• Works on iPhone and iPad

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Auto-Optimize now shows the expected file size for each video — and a total for the whole queue — with much more accurate predictions.
• Your quality preference is remembered between sessions.
• New filter to hide already-converted videos so it's easier to spot what's still worth shrinking.
• The "converted" badge now shows on videos stored in iCloud.
• Stability and reliability improvements throughout picking, converting, and deleting.
