Często zadawane pytania
Why convert RB to APNG?
Convert to APNG when you need short, looping animation with transparency and image-like rendering quality.
It is a good target for interface demos, animated icons, stickers, overlays, product walkthrough fragments, and web assets that must preserve sharp text or crisp edges.
Choose APNG over GIF for better color and transparency, and over MP4 when a transparent animated image is easier to embed than a video element.
It is less appropriate for long clips, large dimensions, or bandwidth-sensitive video delivery.
