Video Compressor & Stabilizer

Phone out of storage again? You don't have to delete your videos and photos to make room. Aisu shrinks them right on your phone, and the big originals go to the trash only if you choose. Your memories stay. They just take up far less space and still look good to watch and share. It also gets a video small enough for WhatsApp or Discord.

🎬 Shrink videos instead of deleting them

• Long clips and 4K videos take up far less room.

• Choose a target size: 10 MB for Discord, 16 MB for WhatsApp, 25 MB for email, or any size you type.

• Compress several videos at once, or share one straight from your gallery to Aisu.

• Check a short before-and-after clip before you start.

• Then trash the big originals to get your space back. Free Up Space shows how much you'll get back first, and you have 30 days to undo (Android 11 and up).

🎥 Video stabilizer for shaky clips

Smooth out the shake in videos you shot while walking or holding the phone. The edges are cropped a little to keep the picture steady.

📷 Compress images to the KB you need

• A form or job application wants a photo under 50 or 200 KB? Pick 50, 100, 200 or 500 KB, 1 MB, or type your own limit.

• Resize images by megapixels, from 2 MP to 24 MP.

• Compress one photo or a whole batch, and convert iPhone HEIC photos to JPG.

• Strip the location from a photo before you share it.

🙈 Blur faces before you share

Blur every face in a video, or only the people you choose, with blur, mosaic or emoji.

🔒 Private and offline

Everything happens on your phone. Your videos and photos are never uploaded, and the app works without internet. No watermarks.

Aisu is free. Premium is a one-time purchase that removes ads and lets you compress more than 10 videos in one go, no subscription.

⚙️ For power users

• Video: H.264 (AVC) or H.265 (HEVC), saved as MP4. MOV files come out as MP4 too.

• Audio: AAC at 64 to 320 kbps, or the original track copied without re-encoding.

• Resolution: 360p to 4K (4K to 1080p, for example), or keep the source. Never upscaled, and downscaling uses Lanczos.

• Frame rate: keep the source or cap it at 24, 25, 30 or 60 fps.

• Bitrate: VBR or CBR from 0.5 to 50 Mbps, or a target file size in MB. Save your settings as presets.

• Performance: hardware-accelerated encoding, up to 3 videos in parallel when the chipset allows, and it keeps running in the background.

• Photos: opens JPEG, PNG, WebP and HEIC and saves JPEG, WebP or PNG, so WebP to JPG works too. Quality 1 to 100, resize by long side or megapixels.

• EXIF: keep it all, only the date, or none.
