Video Compressor & Stabilizer

Compress video and reduce video size in seconds, keeping the picture crisp. Aisu Video Compressor shrinks big, high-resolution clips into small, share-friendly files — free up phone storage and finally send long videos on WhatsApp, TikTok, Instagram, Discord, Messenger or email without hitting upload limits. No more "file too large" errors. Aisu is a video stabilizer too, so shaky handheld clips come out steady.



🎬 Why Aisu Video Compressor?

Camera videos are too big to share or store. This video size reducer cuts file size dramatically while keeping detail sharp — all on your device, offline and private. No watermark, and premium is a one-time purchase, not a subscription.



🎥 Stabilize shaky video

The built-in video stabilizer smooths camera shake into steady footage, one video at a time, entirely on your phone.

• 📈 Motion analysis first — Aisu tracks the motion on a temporary copy (your original is untouched), then charts shakiness over time, scene cuts, peak shake and tracking confidence, and proposes a plan estimating "X% less shake".

• 🎚️ Gentle, Balanced or Strong — stabilizing crops in slightly, so you choose how much frame to trade for steadiness. Dynamic zoom lets the crop drift and absorb more shake.

• 🔧 Per-segment control — the clip splits into Steady, Mild, Very shaky and Extreme stretches; skip any segment or give it its own crop.

• 🏷️ Keep the original quality, or stabilize and compress in one pass; results carry a Stabilized badge in history. Rolling-shutter "jello" wobble can't be fully removed, and Aisu warns you when a clip is already steady.



✨ Key features

• 🎯 One-tap Fit to Size — tap a destination and hit its real limit: WhatsApp 16 MB, Discord 10 MB, Instagram DM 25 MB, Email 25 MB, TikTok 72 MB, Messenger 100 MB, or a custom size. A whole-video analysis pass lands the result on target, not over.

• 📤 Compress & share in one go — share into Aisu as Compress or Stabilize; when it finishes the share sheet opens, straight to WhatsApp, TikTok and more.

• 👀 Before/after preview — compare original and compressed with a wipe divider, full screen if you like, and sample 10 seconds of each clip first.

• 📊 Live estimate — "Estimated output ≈ X" updates as you pick a target, so the final size is never a surprise.

• 🗑️ Free Up Space — see every version of a video (original plus each compressed copy), keep the one you want (the smallest is suggested) and send the rest to the system Trash, recoverable for 30 days, with a live count of the space you free.

• 📉 Smart compression — shrink 4K and 1080p clips with minimal quality loss.

• 📦 Batch compressor — no 10-video limit; queue as many as your device handles, then pause, resume, reorder or clear anytime. The durable queue survives restarts, so big files never silently fail.

• ⚡ Optional simultaneous compression — several videos at once, as many as your device allows.

• 🎛️ Fine control — set resolution, bitrate, an fps cap and sharpness that restores detail lost to downscaling, per video or saved as a preset.

• 🧩 H.264 (AVC) and H.265 (HEVC) presets — HEVC roughly halves the file size at the same quality.

• 🕓 History and a space-saved dashboard show how much you have reclaimed.

• 📁 Supports MP4, MOV and other common formats.

• 🗂️ Save to the app folder, a folder you pick, or the original's folder.

• 🌍 Available in 13 languages.

• 🔒 100% private and offline — compressing and stabilizing run on your device; nothing is ever uploaded.
