Frequently asked questions
How do I compress a video for free?▾
Upload the video, pick a compression level and press Compress video. It is free, adds no watermark and needs no signup or app.
How do I compress a video to a specific size?▾
Choose Target size and enter the size in MB, such as 25 for email or 10 for Discord. The bitrate is set from the video length so the file lands just under that size.
Will the quality drop?▾
Balanced keeps the video looking sharp on phones and laptops while cutting the size a lot. Use High quality for detail, or a lower resolution such as 720p for the smallest files.
Which browsers can compress video?▾
Compression uses the browser's built-in video encoder, so it works in recent Chrome, Edge, Safari and most Android browsers. Firefox support depends on the version.
Is my video uploaded anywhere?▾
No. The video is compressed on your device, so it never leaves your computer or phone and large files need no upload time.
