GIF to AVIF Converter
GIF to AVIF: a compact picture from the first frame, or all frames in a ZIP. First frame or all frames in a ZIP, adjustable quality. No uploads to a server.
AVIF gives the lightest file at good quality but takes longer to encode. The codec is downloaded the first time.
This page turns GIF into AVIF, one of the most compact formats. A still GIF becomes a light file, and for an animated one the first frame is taken or all frames are saved in a ZIP. Transparency is kept.
GIF is an old format with a palette of up to 256 colors. It supports simple animation and full transparency, but not semi-transparency, and it is poor for photos. Still, GIF plays almost everywhere: in messengers, on forums and on social networks.
AVIF is a next-generation format: at the same quality the file is noticeably lighter than JPG and WebP, and transparency is supported. The price is encoding time and compatibility: modern browsers open AVIF, but not all programs do.
For AVIF you set the quality from 1 to 100 and the encoding speed: the slower it is, the slightly lighter the file. A small codec is downloaded on first use. Transparency is kept by default, but you can fill it with a color. GIF can be animated but AVIF cannot store animation: the first frame is taken or all frames are saved as separate pictures in one ZIP. The size in pixels can stay as it is or be changed by width, by height or in percent. Results download one by one or all at once as a ZIP, with random or original names.
Converting GIF to AVIF happens in your browser: files are not uploaded to a server, so it is fast and safe. You can drag several files in, pick them in a file window or paste from the clipboard with Ctrl+V. To encode AVIF a small codec is downloaded on first use, so an internet connection is needed, but the picture itself is never sent anywhere.
