Video compressor FAQ
Is this video compressor free?
Yes. Compress, trim, crop and convert as many videos as you like, with no account, no file size cap beyond 4 GB and no watermark.
Is my video uploaded?
No. The video is read and encoded in your browser and never leaves your device. That’s also why large files work: nothing has to upload.
How do I make a video fit under 10 MB or 25 MB?
Choose File size and pick 10 MB or 25 MB, or type any size. The compressor picks the bitrate and resolution to fit. Longer videos need lower resolution to fit a small size; if the size is too small for the length, it tells you the smallest that works.
How long does it take?
It depends on your device and the video. Encoding uses your computer’s or phone’s video hardware where the browser allows it; a few minutes of 1080p video usually takes a few minutes or less on a recent laptop. Trimming and removing audio copy the video without re-encoding, so they take seconds.
Will compressing lower the quality?
A little: smaller files keep less detail. Balanced keeps up to 1080p and looks close to the original for most clips. High quality keeps the full resolution. Each preset stays well below the original’s bitrate, so the file always gets smaller.
How do I convert MP4 to MP3?
Open the Audio tab, choose MP3 and a quality (192 kbps is a good default), and save. M4A keeps the original sound without re-encoding when the video already has AAC audio.
Does changing the speed change the pitch of voices?
No. The sound is time-stretched so voices keep their pitch from 0.25× to 4×. You can also remove the sound.
Which formats come out?
Compressed, cropped and speed-changed videos are MP4 (H.264 with AAC sound), which plays everywhere. Trims and audio removal keep the original format. Browsers without an H.264 encoder save WebM instead.
