Zen Optimizer vs Video Compressor

Your iPhone is full. Your memories do not have to disappear. Zen Optimizer is a private photo and video compressor that reclaims storage directly on your iPhone or iPad. Choose your media, preview the potential savings, and decide exactly what to optimize. Processing stays on your device—no cloud upload, account, or external server. MORE SPACE, SAME MEMORIES • Compress photos and videos in batches • Preview estimated storage savings before you start • Choose the balance between file size and visual quality • Keep, optimize, or remove items with simple controls • Review before-and-after sizes in your optimization history HOW IT WORKS 1. Select photos and videos from your library 2. Review their size and estimated savings 3. Choose an optimization level 4. Confirm what happens to the originals 5. See the space reclaimed when the job completes PRIVATE BY DESIGN Your photos and videos remain on your device. Zen Optimizer does not require an account and does not send your media to a cloud compression service. Ideal when large videos fill your camera roll, your storage is running low, or you want smaller media files without giving up the moments that matter. Reclaim space with control. Keep the memories.

Your videos are eating your storage. Deleting them hurts, and cloud plans add up — LeanVid opens a third way. It compresses videos by lowering only the bitrate while preserving quality (resolution, frame rate, color, HDR, and every track), then safely replaces the originals — but only after each result passes an integrity check. Free, no account needed, and everything happens on your device. Videos from the Files app such as MKV, WebM, and AVI are converted to MP4 that plays on iPhone, and compressed along the way. ■ MADE FOR YOU IF • You keep seeing "iPhone Storage Almost Full" • You can't bring yourself to delete family or travel videos • You'd rather not add another monthly fee just for more cloud storage ■ COMPRESSION THAT PROTECTS QUALITY • By default it lowers only the bitrate and leaves resolution and frame rate as they are • Want it smaller? You can also lower the resolution (4K to FHD or HD, HD to 480p) and frame rate (60, 30, or 24 fps), for all videos or one by one • Best-effort preservation of HDR (HDR10, HLG, Dolby Vision compatible) and color information • Audio, subtitle, and metadata tracks are copied as-is (only audio that MP4 can't hold is converted to AAC) • Compare before and after with side-by-side, top-bottom, or slider playback — see for yourself, then decide • Detailed spec comparison: codec, bitrate, HDR, frame rate, and more ■ VIDEOS OUTSIDE YOUR PHOTO LIBRARY, TOO • Pick videos from the Files app (On My iPhone, iCloud Drive) and compress them • Files your iPhone can't play are handled by the built-in converter — MKV, WebM, AVI, WMV, FLV, TS, MPG and VOB files with VP9, AV1, VP8, MPEG-1/2/4, DivX, Xvid, WMV or Motion JPEG video • Their audio (AAC, MP3, AC-3, Opus, Vorbis, WMA, PCM) is converted along with the video; subtitle tracks and iPhone spatial audio are not carried over • Replace the original file or save the result to your photo library ■ SAFEGUARDS FOR YOUR ORIGINALS • Replacement proceeds only after the result passes integrity verification • Deleting originals goes through the iOS system confirmation, and they stay in Recently Deleted for 30 days • A recovery journal safely rolls back interrupted work if the app quits mid-task • Compression history lets you re-compare or export anytime ■ SAVINGS THAT REPEAT EVERY MONTH • A lighter library lowers your cloud usage too • Once usage drops below a plan tier, downgrading one step saves you money automatically every month • Not a one-time cleanup — savings that show up on every bill ■ NO WAITING AROUND • Compression continues in the background (iOS 26+ devices; earlier versions pause and auto-resume) • Track progress from the Lock Screen and Dynamic Island with Live Activities • Sort by size, date, or date added (iOS 26 or later) to start with the biggest or the newest videos • Videos stored in iCloud are downloaded and processed automatically ■ PRIVACY • Everything happens on your device — no data about your videos is ever collected or transmitted • No contradiction: an app that cuts your cloud fees never uploads your videos to a cloud of its own About the permission it asks for LeanVid needs access to your photo library to find compressible videos and to replace originals after verification. Originals are deleted only with your confirmation. Videos from the Files app need no extra permission — only the files you pick are accessed.
