Frequently Asked Questions
How can a ~3MB app deliver high-quality animations?
A small download doesn't mean compromised quality. TransMov is built natively for macOS, so it doesn't need to pack a large cross-platform runtime. That keeps the app light, while still letting you preview animations smoothly and export to APNG, GIF, and WebP—all on your Mac.
How do I convert a video to APNG on macOS?
You can convert a video to APNG by importing your video into TransMov, selecting APNG as the output format, and exporting the animation. Everything is processed locally on macOS.
Does GIF support transparency?
GIF only supports 1-bit transparency (fully on or off), which can cause jagged edges. Formats like APNG and WebP support full alpha transparency for smoother and more natural results.
What is the difference between APNG and GIF?
APNG supports full color and alpha transparency, while GIF is limited to 256 colors and basic transparency. APNG generally produces higher-quality animations, especially for UI and gradient-heavy content.
Can I remove video backgrounds locally on Mac?
Yes. TransMov uses the Apple Vision framework and on-device processing to remove video backgrounds without uploading files, ensuring privacy and fast performance.
Which format is best for web animations?
It depends on your needs. GIF is widely supported, APNG offers better quality with transparency, and WebP provides better compression in many cases. For UI and design assets, APNG or WebP are often preferred.
