    FAQ

    Can I zoom?

    Browser zoom (Cmd-+ / Ctrl-+) works on the rendered image. The viewer fits the image to ~70% viewport height by default.

    Why don't I see transparency?

    Make sure the source has an alpha channel (run it through Inspector to confirm). The checkerboard background only appears around transparent pixels.
