Is there a way to decrease polycount without mangling the textures?

[White-waluigi]

Whenever I export the models, they have a huge polycount, making them unsuitable to use in production.
I've tried a few methods to mitigate this but they all got up and downsides:

Blender decimate: Works, but mangles textures somewhat
MeshAnything: Doesn't support textures

Is there an other way to simplify meshes while still preserving the textures?
