# Compress a video to a specific size

Choose a video and type a size limit in MB. The tool divides that size by your video's length to get a bitrate, lowers the resolution when the bitrate is small, and encodes on your device. It then measures the result and retries up to two more times if needed. If the target is impossible, it says so.

Runs on your device

## How it works

1. Choose a video up to 120 MB, or 60 MB on a phone.
2. Pick a common limit or type your own size in MB.
3. Turn on Remove the audio if you need more room for the picture.
4. Press Compress, keep the tab open, and download the MP4.

## Key facts

- **Output**: H.264 video and AAC audio in MP4
- **Size guarantee**: Checked in bytes, 1 MB being 1,000,000 bytes
- **Attempts**: Up to three, each at a lower bitrate
- **Quality floor**: 50 kbps of video, below which it reports the target as too small
- **File limit**: 120 MB on a computer, 60 MB on a phone
- **Your file**: Processed inside this tab and never uploaded

## Common uses

- Meet the upload limit on a job application or a government form.
- Fit a clip under an email attachment limit.
- Send a recording through a chat app that caps file sizes.
- Submit a video assignment to a course site with a size cap.

## Questions

### How is the bitrate worked out?

Your target size in bits divided by the video's length gives the total bitrate. About 4 percent is held back for container overhead, the audio gets a share based on what remains, and the video gets the rest.

### Why was my resolution lowered?

A small bitrate spread across a large picture looks like blocks. When the bitrate is low, the tool picks a smaller resolution so the picture stays cleaner. You can trim the video to keep a higher resolution at the same size.

### What happens if the target cannot be reached?

You get an error with no file, and it names the size the video would need or the smallest result it managed. Pick a bigger target, remove the audio, or trim the video and try again.

### Is my video uploaded anywhere?

No. The video engine runs inside your browser tab and reads the file from your device. ToolSugar's servers never receive it, and closing the tab clears the working copy from memory.
