Shrink MP4, MOV, WebM, AVI and MKV videos in your browser — no upload, no signup.
Video Compressor shrinks the file size of MP4, MOV, MKV, AVI and WebM videos while keeping them looking sharp, so they're easier to email, message or upload elsewhere. A quality slider lets you trade a bit of sharpness for a smaller file, so you decide how far to push it. Everything happens right here in your browser — your device does the work instead of a server, so your footage is never uploaded anywhere, however long or personal it is. Because nothing leaves your computer, larger clips can take a few minutes to process; a progress bar keeps you posted while it works. Only working with one format? The dedicated MP4, MOV, WebM, AVI and MKV compressors below are tuned for that format specifically.
Drag and drop your MP4, MOV, WebM, AVI or MKV files, or click to browse. You can add several at once.
Use the slider or a quick preset, then click Compress. A progress bar shows you how it's going — everything happens on your device, so it can take a few minutes for a longer clip.
Save each file individually, or download every compressed file at once as a .zip.
Your videos are processed locally and never leave your device.
Works straight in your browser — no software, no account, no email.
A live slider shows you the size trade-off instead of guessing at one fixed setting.
Compress as many videos as you like, with no limits or hidden fees.
