GIF to APNG Converter

Convert GIF animations to APNG format instantly in your browser. No upload to server, no signup — fully private and free.

What is GIF?

GIF (Graphics Interchange Format) is a widely used image format that supports animation through multiple frames. It uses lossless LZW compression and is limited to a 256-color palette per frame.

What is APNG?

APNG (Animated Portable Network Graphics) is an extension of PNG that adds support for animations. It supports 24-bit true color and alpha transparency, making it superior to GIF in terms of visual quality.

Why Convert GIF to APNG?

Better Color Quality: 24-bit color vs 256 colors.
Full Alpha Transparency: Smooth edges on backgrounds.
Smaller File Sizes: More efficient compression in many cases.

Frequently Asked Questions (FAQs)

Does this tool resize the animation?
