GIF to AVIF Converter

A Python tool for converting .gif files (or folders containing .gifs) and into animated .avif files using avifenc and Pillow.

Keeps gif transparency and frame durations intact for the final .avif file

the resulting .avif file is placed in the same folder as the .gif file

---

Usage

python gif_to_avif.py path/to/gif_file.gif [--quality N]

or

python gif_to_avif.py path/to/folder/ [--quality N]

--quality N: (optional, default 60) (integer: 0 <= N <= 100)

Note: quality above 90 isn't worth the trouble, you won't really see quality improvement and the file size can be bigger than the original .gif file

Recommended settings:

• basically lossless: 90
• little compression & super high quality: 80
• compression & great quality: 60
• good compression & fine quality: 40
• great compression & some detail: 30
• full compression: 20
• maybe some pixels left: 10

Note: noisy gifs lose their detail faster than smoother gifs, they are also harder to compress

Requirements

• Python 3.7+
• Pillow
• avifenc

Note: avifenc must be callable from commandline from the .py file with:

avifenc [commands]
