Good to know
- For an animated WebP only the first frame is used.
- AVIF is not opened by every app yet (older Windows, some editors and printers). Use JPG or WebP if you need the widest support.
- Both formats are lossy, so every conversion costs a little quality. Keep your original file.

WEBP vs AVIF
WEBP
A WebP file is a modern image format from Google that compresses smaller than JPG or PNG at the same quality, while supporting both lossy and lossless modes plus transparency. It's now the format most websites serve automatically to speed up page loads.
Used in: Modern websites · Faster page loads · Automatic image optimization
AVIF
An AVIF file uses newer, more efficient compression than WebP, producing noticeably smaller files at the same visual quality. Major browsers now support it, and it's becoming the new default for performance-focused websites.
Used in: High-performance websites · Modern browsers · Bandwidth-sensitive apps
