## What CC BY 4.0 Lets You Do

You are free to share, meaning copy and redistribute the material in any medium or format. You are free to adapt, meaning remix, transform and build upon it for any purpose, even commercially.

Redistribution is encouraged as long as you follow the licence terms. Credit the creator, link to the licence, and indicate if you changed anything. You can do that in any reasonable way, as long as it does not suggest we endorse you.

## Attribution, In Practice

Attribution is required for all free assets, not only the open-source sets. Give appropriate credit and provide a link to streamlinehq.com wherever the icons appear.

Pro removes that requirement. If a credit line does not fit the project, that is the reason to upgrade rather than a licence to skip it.

## Depth Over Breadth

We go deep. Streamline builds massive, complete icon sets designed to cover every use case you'll ever need. You won't discover a gap, then end up drawing the icons yourself or mixing sets that never quite match.

Streamline makes the largest icon packs so you never have to mix and match different packs together. The sets don't compete. They add up to one coherent library that respects your time.

## Master The Craft

Everything is made in-house by one team of veteran icon designers. That's how we get true consistency.

We go back to older icons and improve them. Ultimate has been improved five times since it originally launched, and some of our icons are better than custom drawn ones.

## Frequently asked questions

Quick answers about the CC BY 4.0 licence on Streamline icons.

### What is the CC BY 4.0 licence?

Creative Commons Attribution 4.0 International. It lets you share and adapt the work for any purpose, including commercial work, so long as you credit the creator, link to the licence, and indicate any changes. The full terms are at [creativecommons.org/licenses/by/4.0](https://creativecommons.org/licenses/by/4.0/).

### Can I use these icons commercially?

Yes. Commercial use is explicitly allowed, and you can use the assets across unlimited projects.

### Do I have to credit Streamline?

Yes. Attribution is required for all free assets, and the credit must be a link to the Streamline website rather than to a Figma file or a GitHub repository.

### How do I attribute correctly?

Give appropriate credit and link to streamlinehq.com wherever the icons appear. The full terms are on [streamlinehq.com/free/license](https://www.streamlinehq.com/free/license).

### Which sets are CC BY 4.0?

The free sets across the ten families shown above, plus Block, Stickies, Nasty, Covid, Typeface and Logos, which are on the same list.

### Are the pro sets CC BY 4.0 as well?

No. The licence covers the free sets. Pro sets come under the Streamline licence, which drops the attribution requirement and opens the rest of the library.

### What formats can I download on the free tier?

For free sets you get SVG, PNG and PDF. Free previews of premium sets are low-resolution PNG only, up to 48px for icons and 400px for illustrations.

### Does the API or the MCP change the licence?

No. Pulling assets through the API or the MCP does not change the terms, which follow whatever plan you are on. See [streamlinehq.com/mcp](https://www.streamlinehq.com/mcp) for how the connection works.
