Operation process
Compress video online free in three steps with previewed sizes and quality-first encoding.
Step 1
Upload your file
Drop an MP4, MOV, or WebM and pick a target like 720p, 1080p, or a max file size for email or messaging.
Step 2
Pick compression level
Choose balanced, high-quality, or small-size mode. Preview bitrate and estimated output size before you compress video online.
Step 3
Export and share
Download a clean, smaller MP4 that stays sharp on TikTok, Instagram Reels, YouTube Shorts, or client handoffs.
Principle & pipeline
The compressor balances bitrate, resolution, and audio depth so you reduce video size without throwing away clarity.
Bitrate-aware encoding
Sets a target bitrate based on your size or resolution goal, keeping motion smooth and edges clean.
Balanced profiles avoid harsh macroblocking, and a single-pass export prevents extra quality loss. Useful when you need to reduce MP4 size for email or cloud uploads.
Resolution and audio tuning
Downscale only when necessary and pair it with smart audio bitrates so voices and music stay clear.
The pipeline keeps aspect ratios intact for vertical, square, or landscape videos—ready for TikTok, Reels, Shorts, or desktop playback without stretching artifacts.
