Quick answer: how do you compress a video for free?
Upload your MP4, MOV, WebM or MKV file (up to 40 MB), pick a compression level, click Compress Video and download the result. This tool re-encodes your video at a lower bitrate but never scales it down, so the width and height stay exactly the same.
How to compress a video in 4 steps
- Add your video. Drag it in or click the upload box. Files must be 40 MB or smaller.
- Choose a level. Balanced suits most videos. Pick High quality for the closest match to the original.
- Click Compress Video. Watch the progress bar. Everything runs on your device.
- Preview and download. Check the result in the player, then click Download MP4.
Why use our free video compressor
Resolution never changes
A 1080p video stays 1080p. We reduce the bitrate only, so the picture is not shrunk or stretched.
Private by design
Your video is processed inside your browser. It is never uploaded to our servers.
Fast on modern devices
It uses your device's built-in video encoder, so it is much quicker than most in-browser tools.
No limits on use
Compress and download as many videos as you like. No account, no watermark, no daily cap.
What is video compression and when do you need it?
Video compression lowers the number of bits used per second of footage (the bitrate) so the file gets smaller. Smaller videos upload faster, load quicker on websites and fit inside email and messaging limits. Gmail, for example, caps attachments at 25 MB, and WhatsApp limits video sharing to around 16 MB.
For small businesses this matters every day. A product demo on your WooCommerce store, a testimonial clip for your landing page or a promo for social media all perform better when they load fast. Heavy videos slow pages down, which hurts both visitors and search rankings.
Why the resolution stays the same
Many compressors shrink the frame size to save space, which is what makes video look soft or blurry. Our tool does not do that. It keeps your width, height and frame rate, and lowers only the bitrate. Compression is always lossy to some degree, but at the Balanced level most viewers cannot see the difference on a phone or laptop screen.
Tips to get the best result
- Trim first. Cutting unused seconds saves more space than any setting.
- Start with Balanced. Move to High quality if you see artifacts in fast motion.
- Use MP4 for the web. The output is H.264 MP4, which plays on virtually every browser and phone.
- Expect different savings. Screen recordings often shrink a lot. Videos already compressed by a phone or editor may shrink less.
- Host big videos on YouTube or Vimeo. Embed them on your website instead of uploading heavy files to WordPress.
Limits and supported browsers
The free tool accepts videos up to 40 MB. A file larger than that shows an error message and is not processed. It works in current versions of Chrome, Edge, Safari and Firefox that support the WebCodecs feature. If your video is already highly compressed, the tool tells you instead of giving you a bigger file.
Frequently asked questions
Is this video compressor really free?
Yes. It is completely free, with no signup, no watermark and no limit on how many videos you compress or download.
How do I compress a video without losing resolution?
Use a compressor that lowers the bitrate instead of resizing the frame. Our tool does exactly that, so a 1080p video stays 1080p after compression.
What is the maximum video size I can compress?
The maximum is 40 MB per video. Larger files, such as a 42 MB video, show an error message and cannot be compressed with this free tool.
Will compression make my video blurry?
No frame shrinking is applied, so the video is not made blurry by resizing. Any compression removes some fine detail, so choose High quality if you want the closest match to your original.
Is my video uploaded to your server?
No. The video is compressed inside your browser on your own device and is never uploaded to our servers.
Which video formats are supported?
You can add MP4, MOV, WebM and MKV files. The compressed video is saved as an H.264 MP4 file.
Why did the tool say my video is already compressed?
Some videos are already encoded at a low bitrate. Compressing them further would either reduce quality noticeably or make the file bigger, so the tool stops and keeps your original.
