# Compress a video without uploading it

Choose a video, pick Smaller file, Balanced or High quality, and optionally cap the resolution at 1080p, 720p or 480p. The tool re-encodes to H.264 MP4 inside your browser and tells you how much smaller the result is. Encoding is slow in a browser, so short clips work best.

Runs on your device

## How it works

1. Choose a video up to 120 MB, or 60 MB on a phone.
2. Pick a quality preset. Balanced suits most videos.
3. Lower the maximum resolution if you need a much smaller file.
4. Press Compress video, keep the tab open, and download the MP4.

## Key facts

- **Output**: H.264 video and AAC audio in MP4
- **File limit**: 120 MB on a computer, 60 MB on a phone
- **Resolutions**: Keep size, 1080p, 720p or 480p, never scaled up
- **Encoding speed**: A minute of 1080p at 30 fps took about 8 seconds on an Apple M4 Pro laptop using its video hardware, and 2 to 4 minutes on the fallback engine. Phones and older computers take longer.
- **First run**: Some jobs download a 32 MB video engine once, then your browser reuses it
- **Your file**: Processed inside this tab and never uploaded

## Common uses

- Shrink a phone recording so it attaches to a message.
- Save storage on a large screen recording that is mostly static.
- Reduce a clip before posting it to a site with slow upload.
- Drop the audio from a silent demo to save extra space.

## Questions

### Why did my video get bigger?

Videos that were already compressed efficiently, such as HEVC clips from a recent iPhone, can grow when re-encoded to H.264. The result tells you when this happens. Keep your original, or try Smaller file with a lower resolution.

### Which setting saves the most space?

Lowering the resolution usually saves the most, and it also makes the encode faster. Going from 1080p to 720p cuts the number of pixels by more than half. Removing the audio helps on quiet talking head clips too.

### Can I choose an exact file size?

Not here. These presets aim for a quality level, so the final size depends on the video. Compress to Size works out a bitrate from the length of your video and checks the result against your limit.

### How do I compress a video without losing quality?

Every re-encode loses some detail, so the goal is a loss you cannot see. Lower the resolution only as far as your screen needs, then compare the result with your original before you share it.

### How do I make a video small enough for email or WhatsApp?

Check the size limit of the app you are sending through, then enter that number in Compress to Size. Lowering the resolution here also helps when you only need a smaller file.

### How large a video can I compress?

Up to 120 MB on a computer and 60 MB on a phone, because the video is encoded inside your browser tab and has to fit in its memory.

### 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.
