# How do I limit how much bandwidth a transfer uses?

Set **Bandwidth limit** under **Advanced options** in **New Transfer**. Type a number with a suffix:

- `10M` — about 10 megabytes a second (roughly 80 megabits a second, the unit internet plans usually use).
- `100k` — about 100 kilobytes a second.

Leave it empty for no limit. A capital **M** means megabytes and a lowercase **k** means kilobytes.

A limit is useful for big uploads on a shared or slow connection, or while you're on video calls. The limit applies to that transfer only; to change it later, create the transfer again with a new value.
