How to Use Video Compressor
About Video Compressor
Shrink video clips for WhatsApp, email, Discord and web publishing without uploading them. Choose a target resolution (1080p, 720p, 540p, 480p) and a bitrate preset (0.65 Mbps for the smallest files, 1.2 Mbps balanced, 2.5 Mbps high fidelity), then watch real-time progress while your own device does the encoding. If a result would not actually be smaller than the original, the tool tells you instead of pretending.
Frequently Asked Questions
How does in-browser video compression work?
We use WebAssembly-compiled FFmpeg. Your device CPU executes the video re-encoding locally without uploading gigabytes of video over the web.
Why does video compression take longer than image compression?
Video files contain thousands of individual frames that must be decoded, scaled, and re-encoded. For best performance, use moderate clip lengths (under ~2 minutes on free tier).
What if I navigate away from the tab during compression?
Because compression runs locally in browser memory, closing the tab terminates the process. Please keep the tab open until finished.
