How to compress a video
- Drop your video on the box above, or click to choose it.
- Pick a preset: Balanced for good quality at a smaller size, or WhatsApp, Email or Discord to aim for a size limit.
- Press Compress video and wait for the progress bar to finish.
- Download the file and compare the sizes shown on the result card.
Presets explained
| Preset | What it does |
|---|---|
| Balanced | Medium compression level. Good for most videos. |
| Aims for about 15 MB. | |
| Aims for under 23 MB, which fits most mail limits. | |
| Discord | Aims for under 10 MB. |
| Smallest | Lowest quality level and 480p. Use when size matters more than looks. |
Target size mode
Type a size in MB and the tool sets the video bitrate from the length of your video, leaving room for sound. If your video is too long for the size you asked for, it tells you instead of making an unwatchable file. If the result lands a little over the target, the result card suggests a smaller number to try. Results are close to the target but not exact, because the encoder decides frame by frame.
Tips for a smaller file
- Lower the resolution. 720p looks good on a phone and saves a lot of space.
- Remove the sound if you do not need it.
- Cut out parts you do not need with the handles, so you only compress the part you want.
- A video that was already compressed may not shrink much. The tool says so when that happens.
Limits
Compression always re-encodes the video, so long or high-resolution files take time and depend on your device. Very large files can run out of browser memory; compress a shorter part if that happens. Compressing twice lowers quality each time, so keep your original.
Privacy
Your video never leaves your device. The page loads the processing code once, then reads and writes the file inside your browser. There is no upload, no account and no watermark.
FAQ
Does compressing lower the quality?
Yes, a little. Smaller files hold less detail. Balanced is chosen so the loss is hard to see on a phone screen.
Can I compress a video for WhatsApp?
Use the WhatsApp preset, which aims for about 15 MB. Longer videos may need a smaller custom size.
Is there a file size limit?
No upload limit, because nothing is uploaded. The limit is your browser memory, so very long videos may fail.
Which formats can I use?
MP4, MOV, WebM and MKV inputs that your browser can decode. The output is MP4, or WebM if you choose it.
Why did my file barely shrink?
It was probably compressed already. Try a lower resolution or the Smallest preset.
Will it keep the sound?
Yes, unless you choose Remove sound. Sound quality can be set in target size mode.
