Compress Video Online to Any Size You Want
Large video files are hard to share. Email services reject attachments above 25 MB, messaging apps limit uploads, and cloud storage fills up quickly. This free online video compressor solves the problem in a simple way: you upload a video, the tool shows its exact original size, and you decide how big the final file should be. Enter a number in megabytes or gigabytes, press one button, and download the result. Everything runs inside your own browser, so your footage is never sent to a server.
How to Use the Video Compressor
- Upload your video. Click the upload box or drag a file onto it. The tool instantly displays the original file size, duration and resolution.
- Enter the size you need. Type a value in the target size box and choose MB or GB. For example, type 20 and select MB to get a file of about 20 MB.
- Click Compress video. The video is re-encoded in your browser. A progress bar shows how far along it is. Keep the tab open and visible until it reaches 100%.
- Download. When finished, the new size and the amount saved appear. Click the download button to save the compressed file.
Key Benefits
You control the final size
Most compressors give only vague options such as low, medium or high quality. Here you choose the exact target, which is useful when a platform has a strict limit like 8 MB, 25 MB or 100 MB.
Private by design
Your video never leaves your device. There is no upload, no waiting for a server queue, and no risk of personal clips being stored by a third party. This makes the tool suitable for family videos, work recordings and confidential material.
Free, with no watermark
There are no accounts, subscriptions or logos burned into your video. Use the tool as often as you like.
Works on any modern device
The compressor runs in Chrome, Edge, Firefox and Safari on desktop and many mobile devices. Nothing needs to be installed.
Smart quality balance
The tool calculates the bitrate needed to reach your target size. If the target is very small, it also reduces the resolution so the picture stays clean instead of turning blocky.
When Should You Compress a Video?
- Sending clips by email, WhatsApp, Telegram or Slack.
- Uploading assignments, application videos or portfolio reels to sites with size limits.
- Saving phone storage by shrinking old recordings.
- Making website videos load faster, which improves user experience and SEO.
- Reducing mobile data use when sharing videos on slow connections.
Tips for the Best Results
- Choose a realistic target. Shrinking a 1 GB video to 5 MB will cause visible quality loss.
- Keep the browser tab active while compressing, because background tabs can be slowed down.
- Compression time is roughly equal to the video length, since the browser processes it in real time.
- If your target is larger than the original, the tool will warn you, as compression cannot add quality.
Frequently Asked Questions
Is this video compressor free?
Yes. It is completely free, with no sign-up and no watermark.
Is my video uploaded anywhere?
No. All processing happens locally in your browser, so your file stays private.
How accurate is the target size?
The result is usually within a few percent of your target and normally slightly smaller, because the tool leaves a safety margin for container overhead.
Which format will the output be?
The tool uses MP4 when your browser supports it, otherwise WebM. Both play on almost all devices and platforms.
Why is compression taking so long?
The video is encoded in real time, so a 10-minute video needs about 10 minutes. Keep the tab open.
