AVIF (built on the AV1 video codec) is the current efficiency champion for still images: dramatically smaller files than JPG or WebP at the same visual quality, with HDR, wide color, and transparency. It is the best choice for modern web delivery where every kilobyte counts.
Every tool runs in your browser — files never leave your device. Badges say exactly what each tool does with AVIF.
AVIF encoding currently requires a Chromium browser (Chrome or Edge). Other browsers lack a canvas AVIF encoder, so the tool refuses upfront and suggests WebP instead of failing mysteriously.
AVIF for maximum compression on modern audiences; WebP for universal compatibility today. Both beat JPG — the choice is efficiency versus reach.
Most social apps reject AVIF uploads. Convert AVIF to JPG first for sharing — the file grows, but it will actually post.
No. Encoding happens in your browser via canvas; nothing leaves your device.
