Working with images and file size – WEBP good idea?

Hello all,

here’s a question that probably Figma’s developers can answer best:

When importing images, does using WEBP files help to keep the document / prototype size small?

Will Figma use the imported files as they are or will they be converted to PNG (or an internal bitmap format) regardless of their original file format?

Thanks in advance, I’ll appreciate any experience or insights on this topic from the community or the team themselves.
