GIF to APNG: the animated-frame image encoding route explained
Converter.now decodes the GIF frame sequence, timing, disposal, and canvas, then maps those frames into the animation and color rules available to APNG. A successful first frame does not prove that the complete loop survived. GIF decoding reconstructs indexed-color frames from local palettes, disposal instructions, transparent indices, and centisecond timing values. APNG writes full-color PNG frames with alpha, timing, blend, disposal, and loop controls, but unsupported viewers may expose only the default image.
Canvas decoded from a frame animation or indexed-color image limited to a 256-color palette. Image written as a PNG-compatible sequence of full-color frames with alpha transparency.

Deciding when GIF to APNG is the right conversion
APNG wins this route whenever its specific mix of compatibility, alpha, animation, and file size fits the destination better than GIF does.
What changes between the GIF model and the APNG deliverable
- The source stores a frame animation or indexed-color image limited to a 256-color palette; the destination stores a PNG-compatible sequence of full-color frames with alpha transparency. Compare application metadata after that structural change.
- Treat GIF-specific metadata fields as optional in the APNG result until you have actually confirmed they survived.
GIF source facts versus APNG output requirements
What can fail when Graphics Interchange Format is interpreted
Photographs and gradients can band, semi-transparent edges are reduced, and timing may be quantized.
What Animated Portable Network Graphics cannot safely promise
Apps that lack APNG support may show only the first frame, while frame disposal can affect transparent motion.
How the APNG writer handles this route
The writer builds a PNG-compatible sequence of full-color frames with alpha transparency and labels the result as image/apng. The receiving application - Not the extension alone - Is the final compatibility test.
