Why use Video Compressor
Private and secure
Your video is sent over an encrypted connection to our server in Europe and stored under a random ID. It is never shared with third parties or used to train AI. Download links expire after 60 minutes; files are then deleted automatically, normally within 75 minutes. Read the privacy policy
Honest results
Choose quality, resolution or a target size. Progress comes from the encoder itself, and the result shows the exact size saved, even when a target can't be met.
Free, no sign-up
Video Compressor is free with no account, no watermark and no ads. It works in any modern browser on phone or desktop.
In short
Video Compressor re-encodes your video to MP4 with H.264 video and AAC audio on our server in Europe. You choose a quality preset, a maximum resolution (1080p, 720p or 480p) and what to do with the audio, or set a target size in MB or as a percentage. Progress comes from the encoder itself. Videos up to 1 GB and 30 minutes are supported, from your device or a public link; download links expire after 60 minutes.

How to use it
- Choose or drop a video (up to 1 GB, 30 minutes), or import it from a link.
- Pick a quality preset and resolution, or turn on Target size.
- Select Compress video and keep the tab open while it uploads and encodes.
- Watch the preview, compare sizes and download the MP4.
Choosing quality and resolution
Resolution has the biggest effect on size. A 4K or 1080p phone clip shown in a chat app rarely needs more than 720p. Quality presets then control how much detail is kept at that resolution: High quality keeps fine texture, Balanced suits most sharing, Smaller file is for strict limits.
Output is never upscaled; the shorter side of the frame is capped at the resolution you pick (and at 1080p overall).
Why the result is MP4
MP4 with H.264 and AAC plays in every current browser, on iPhone and Android, and on most TVs. MOV, WebM and MKV inputs are converted to it, and the result says so.
Questions
Is Video Compressor free?
Yes. No account, no watermark, no ads.
How long does it take?
Upload time depends on your connection; encoding time depends on the clip's length, resolution and the speed setting. The progress bar shows real encoder progress, and if others are compressing at the same time you'll see your place in the queue.
Can I compress a video longer than 30 minutes?
Not at the moment. Trim it first, or split it into parts.
What is the maximum file size?
1 GB per video. Large uploads go directly to our server rather than through a CDN, so they don't stall on slow routes.
What happens to my video after compression?
It's stored under a random ID on our server in Europe. The download link expires after 60 minutes and the video is then deleted automatically, normally within 75 minutes. Canceling deletes it immediately.
The compressed video won't play. What can I do?
Output is standard MP4 with H.264 video and AAC audio, which plays on nearly every device. If an old TV or car screen refuses it, compress again with "Works on older devices" under Advanced settings.
