Hi!
I’d like to use Material Symbols in my project. Their website says they are licensed under Apache License 2.0. They are provided both in svg and png formats. However, I need specific resolution, and the best approach would be to convert them from svg to png on my side. Can I distribute these converted images as part of my project and which license can I use for it?
You can modify them, yes, and distribute them with your project. To comply with the terms of Apache 2.0, you must include a copy of Apache 2.0, and summarize the changes you made to the originals. You can distribute the modified versions under Apache 2.0, or, because Apache 2.0 is a permissive license and permits sublicensing, you can apply your own project’s license as well.
In practical terms, I would suggest simply including a copy of the Apache 2.0 license somewhere near the icons in your source repository, along with a small notice explaining where they came from and what you changed.
Material Symbols as a project seems to be pretty laissez faire with the license terms:
We have made these icons available for you to incorporate into your products under the Apache License Version 2.0. Feel free to remix and re-share these icons and documentation in your products. We’d love attribution in your app’s about screen, but it’s not required.
So I think you don’t need to worry too much about getting it perfect.
