FAQ
Is my APNG uploaded to a server?
No. Your APNG stays on your device. TransMov APNG Viewer processes files directly in your browser, so your animations are never uploaded or stored on a server.
What information can I see about my APNG?
You can preview the animation and check details including file name, file size, dimensions, frame count, and duration. You can also switch between checkerboard, black, and white backgrounds to inspect transparency.
Can I edit or convert APNG files here?
This page is designed for previewing APNG files. For editing, conversion, and advanced animation workflows, use TransMov for Mac — a native macOS app for GIF, APNG, and WebP.
Can APNGs support transparency?
Yes. APNG supports full alpha transparency, which usually looks smoother than GIF’s basic transparency. Compare formats in our GIF vs APNG vs WebP guide.
