Compress Video
Compress Video is a free tool that makes a video file smaller so you can send it by email, Discord or text. Pick a target size, such as under 10 MB for Discord or 25 MB for Gmail, and it works out the bitrate and resolution to hit it, or use the quality slider instead. It saves an H.264 MP4 and keeps the sound. Your browser's own video encoder does the work, so the video is never uploaded.

Make a video small enough to send. Choose a target size, like under 10 MB for Discord or 25 MB for email, and the tool works out the rest, or set the quality yourself. You get an MP4 with the sound kept, and your video never leaves your device.

Lower quality makes a smaller file. Around 50 to 70 looks good for most phone videos.

How to Compress a Video
Step by step
- Choose a video from your computer or phone.
- Pick a target size, such as "Under 25 MB" for email, or switch to Quality and move the slider.
- Check the estimate. The tool shows the expected size and the resolution it will use.
- Click Compress video and wait for the progress bar.
- Compare the sizes and download the MP4. Play it on the page first if you like.
How do I compress a video to under 25 MB for email?
Choose "Under 25 MB (Gmail and most email)" and click Compress video. The tool divides the size budget by the length of the video to get a bitrate, leaves room for the sound and the file's overhead, and lowers the resolution if that will look better than a blurry full-size picture. If the first pass still comes out too big, it automatically runs a second, smaller pass. Outlook and some work email limit attachments to 20 MB, so use that preset if you're not sure.
How do I make a video small enough for Discord?
Pick "Under 10 MB (Discord free)." Discord limits uploads to 10 MB for accounts without Nitro. Ten megabytes is tight: a 30-second clip comes out at about 720p, and several minutes will look soft. Trimming the video first with Trim Video keeps the quality much higher.
Will compressing reduce the quality?
Some, yes. Compression works by throwing away detail you're least likely to notice. How much you'll see depends on how much smaller the file gets. Halving the size of a phone video usually looks almost the same, while squeezing a long 4K video into 10 MB will look blurry. The quality mode never makes a file bigger than the original, and the result plays on the page so you can check it before downloading.
Does it keep the sound?
Yes. AAC sound, which most phones and cameras record, is copied over without re-encoding. Other audio formats are converted to AAC, or to Opus on browsers without an AAC encoder (such as Chrome on Linux). Uncheck "Keep the sound" to remove the audio and save a little more space.
Which browsers does it work in?
It works in current versions of Chrome, Edge and Safari 16.4 or newer, on computers, Android phones, iPhones and iPads. Firefox 130 or newer on a computer usually works too. The tool uses WebCodecs, the browser's built-in video encoder, which is often hardware accelerated. If your browser doesn't support it, the page tells you right away.
Is there a file size limit?
Up to 2 GB on a computer and 1 GB on a phone or tablet. The new file is put together in your browser's memory, so very large videos could crash the tab. Long videos just take longer. Speed depends on your device; computers and phones with hardware video encoding are often faster than real time.
Is my video uploaded?
No. Your video is read from your device, processed by your browser and saved back to your device. It never touches a server, which also means there's no upload to wait for. See our Privacy Policy.
