Video Compressor & Stabilizer

Aisu compresses video and photos without losing quality, and steadies shaky footage too. A 4K or 1080p MP4 shrinks to a fraction of its size and stays sharp, so long clips fit WhatsApp, Discord or email. Photos come down to the KB limit you pick, and HEIC shots come out as JPEG. It all runs offline on your phone.

🎬 Why Aisu Video Compressor?

Phone videos are too big to send and often too shaky, and photos fill a phone fast. Most compressors smear the detail or upload your files to a server. Aisu works on your device, keeps the picture sharp and adds no watermark. If no smaller file is possible, you keep the original. It's free to use, in 16 languages, and premium is a one-time purchase, not a subscription.

✨ Compress video and reduce file size

• 🪄 Automatic quality tests Share, Balance and Archive on your video, on your phone, at 4K, 1080p or lower, and offers only the ones that save at least 10%.

• 🎯 Fit to Size aims a video at a limit in one tap: WhatsApp 16 MB, WhatsApp Web 64 or 100 MB, Discord 10 MB, Instagram DM 25 MB, Email 25 MB, TikTok 72 MB, Messenger 100 MB or any size you type. If your phone can't get under it, the result says so.

• ⚖️ Compare shows short samples at each quality side by side or as before and after, and whole photos the same way.

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

• 🎛️ Presets set resolution, bitrate, fps cap and sharpness. Save your own.

• 📦 Batch compression runs several videos at once from a queue you can pause or reorder. MP4, MOV and other formats, saved in a folder you choose or beside the original.

• 🗑️ Free Up Space lists every copy of a video or photo you have. Keep one and trash the rest, with 30 days to change your mind. Or tick "Trash the original when done" before Start.

• 📤 Share a video or photos to Aisu from any app and choose Compress video, Compress photos, Stabilize video or Blur faces.

📷 Compress photos, down to the KB

• 🖼️ Compress photos picks Share, Balance or Archive for the batch and only offers a tier that makes the files smaller. Or set a limit: 50, 100, 200 or 500 KB, 1 MB or your own number, or a pixel count from 2 to 24 MP.

• 🔎 Detail puts back the crispness that shrinking takes away. Natural suits most photos, Strong suits soft ones.

• 🔄 Opens HEIC (Android 9 and up) and saves JPEG, WebP or PNG. Photos already under the limit are skipped, and the results say if one can't get under it.

• 📍 Metadata: keep it all, date only, or none. Remove location strips the GPS before you share.

• 📚 Presets for WhatsApp and messaging, Email attachment, Instagram, Web and blog, Privacy share and Print and full quality. Preview one on a photo before the batch runs.

🎥 Video stabilizer for shaky clips

• 📈 Aisu analyzes the motion first and shows the shake, the cuts and the peaks, plus how much can be removed.

• 🎯 It tracks the camera, so water or a crowd won't throw it off, and real cuts stay cuts.

• ⚙️ Gentle, Balanced or Strong sets how much frame you trade for steadiness. Dynamic zoom lets the crop move with the shot, and Segments let you skip a stretch or crop it on its own.

• 📐 Rolling-shutter correction removes the jello wobble. If a clip is already steady or won't fully come out, it says so upfront.

• 🏷️ Keep original quality, or stabilize and compress in one pass. Results carry a Stabilized badge.

🙈 Blur faces before you share

• 🔍 Aisu finds the faces on your phone. Cover everyone, pick people, or blur the background and keep the faces clear.

• 🎨 Blur, Mosaic, Solid or Emoji, as an oval or a rectangle, with adjustable strength and size.

• ✅ Coverage shows the moments a face slipped out, so you can check before posting. The original stays untouched.
