CompressX: AI Video Compressor

CompressX shrinks large videos on your phone.

Most compressors give you three fixed presets and hope for the best. CompressX looks at your video first: resolution, frame rate, codec, and how much detail and motion it actually contains — then picks the bitrate, resolution and frame rate an expert would pick for that clip. A static talking-head video and a football match don't need the same settings, and CompressX doesn't treat them the same.

SMART COMPRESSION
- Analyzes detail and motion before choosing any settings
- Detects screen recordings and keeps text sharp
- Tells you exactly why it chose what it chose — no black box
- Three modes: Share (smallest), Balanced (default), Best (close to original)
- Quality Lock (Pro): runs a short test encode and measures the result, raising the bitrate until a real quality target is met — so "smaller file, same quality" is measured, not guessed
- HEVC output (Pro) on phones with a hardware encoder — same quality at a lower bitrate

FULL CONTROL WHEN YOU WANT IT
- Presets: 1080p, 720p, 480p
- Target size — hit 10 MB for Discord, 25 MB for email, or any size you type
- Custom bitrate and resolution
- Trim before compressing, or trim losslessly with no re-encode
- Extract audio, or mute a video
- Batch compress up to 20 videos at once (Pro)

FAST AND PRIVATE
- Everything runs on your device — your videos are never uploaded anywhere
- Hardware-accelerated encoding through Android's native media pipeline
- Runs in the background with a progress notification, and cancels cleanly
- Before/after preview and a savings figure on every export
- History of every compression, with its quality score
- Never produces a file larger than the original

GOOD FOR
- Getting videos under the size cap on WhatsApp, Telegram, Discord and email
- Freeing up storage without deleting memories
- Faster uploads on slow connections
- Shrinking long screen recordings and lecture videos
