How to use

Add your video. Drag and drop a video file or click to select one from your device. Nothing is uploaded.
Set your target. Choose a target size, such as under 25MB for Discord or email, or pick a quality level instead.
Compress. Start the compression and watch the progress as your browser re-encodes the video locally.
Download the MP4. Save the smaller MP4 and check that it fits your size limit before sharing.

Features

Hit a real size target. Aim for a specific file size like 25MB so the result fits Discord, email, or upload limits on the first try.
Nothing leaves your device. Your video is processed in the browser with WebCodecs, so there is no upload, queue, or server storing your files.
Fast on modern hardware. WebCodecs taps your device's video encoder for quick compression, with an FFmpeg.wasm fallback when it is unavailable.
Free with no watermark. Compress as many videos as your device can handle, with no sign-up, no paywall, and no logo stamped on your output.
Works offline after loading. Once the page and any fallback engine are cached, you can compress videos without an internet connection.

When to use it

Squeeze a clip under Discord's 25MB upload limit so you can share it on a free server.
Trim a recording down to fit a Gmail or Outlook email attachment.
Reduce a screen recording before posting it to a chat, ticket, or forum.
Make a phone video small enough to message without it being heavily downscaled.
Shrink footage to save storage or speed up uploads to a slow connection.

Is it private?

Your video is compressed locally in your browser and is never uploaded to any server.

Frequently asked questions

Is the video compressor free?

Yes, it is completely free with no sign-up, no watermark, and no limit on how many videos you can compress beyond what your device can handle.

Are my videos uploaded anywhere?

No. Compression happens entirely in your browser using WebCodecs (or an FFmpeg.wasm fallback), so your video never leaves your device and nothing is stored on a server.

How do I get a video under 25MB for Discord or email?

Choose the target size option and set it to 25MB or lower. The tool encodes the MP4 to aim for that size; you can lower the target further if a service has a smaller limit.

What formats and limits are supported?

You can load common video files and download a smaller MP4. There are no fixed file-size caps, but very large or long videos are limited by your device's memory and may be slow or fail on low-memory phones.

Why is the first run sometimes slower?

If your browser cannot use WebCodecs, the tool loads an FFmpeg.wasm engine once. That initial download is cached afterward and then works offline, but the fallback path is slower than native WebCodecs.

Will compressing reduce the video quality?

Making a file smaller always trades off some quality. Targeting a larger size or higher quality keeps more detail; aiming for a very small size will look softer, so pick the balance that fits your needs.

Does it work on my phone?

It runs in modern mobile browsers, but compressing video is memory-intensive. Short clips usually work fine, while large files may be slow or fail on low-memory devices.
