About GIF → AVIF
Why convert GIF to AVIF?
AVIF produces dramatically smaller files than GIF for the same image, which is the main reason to convert. AVIF escapes GIF's 256-colour palette limit and gives you full 24-bit colour. verto converts the first frame only — animation is not preserved. AVIF currently offers the best compression of any mainstream image format, ideal for performance-critical websites.
About GIF
GIF is one of the oldest image formats still in active use, famous for short looping animations. It is limited to a 256-colour palette per frame, which makes it a poor fit for photographs but acceptable for flat graphics and short clips. In verto, GIF is accepted as an input only — animation is flattened to the first frame, because the modern outputs (JPG, PNG, WebP, AVIF) are encoded one frame at a time by the browser's Canvas API.
About AVIF
AVIF is based on the AV1 video codec and currently offers the best compression of any widely-supported web image format — typically 30–50% smaller than JPG and noticeably smaller than WebP for the same perceived quality. It supports transparency, wide colour gamut, HDR and animation. Browser decode support is universal in modern Chrome, Firefox, Safari and Edge, but encode support in the browser is still uneven, which is why verto surfaces a clear fallback message when the local encoder refuses.

GIF
SourceGraphics Interchange Format · introduced 1987
GIF is one of the oldest image formats still in active use, famous for short looping animations. It is limited to a 256-colour palette per frame, which makes it a poor fit for photographs but acceptable for flat graphics and short clips. In verto, GIF is accepted as an input only — animation is flattened to the first frame, because the modern outputs (JPG, PNG, WebP, AVIF) are encoded one frame at a time by the browser's Canvas API.
Strengths
- Universal browser and OS support
- Supports simple animation and 1-bit transparency
Trade-offs
- Capped at 256 colours per frame — terrible for photos
- Larger than WebP/AVIF for the same content
- In verto: first frame only when converting (animation is dropped)
AVIF
TargetAV1 Image File Format · introduced 2019
AVIF is based on the AV1 video codec and currently offers the best compression of any widely-supported web image format — typically 30–50% smaller than JPG and noticeably smaller than WebP for the same perceived quality. It supports transparency, wide colour gamut, HDR and animation. Browser decode support is universal in modern Chrome, Firefox, Safari and Edge, but encode support in the browser is still uneven, which is why verto surfaces a clear fallback message when the local encoder refuses.
Strengths
- Best compression ratio of any mainstream format
- Supports transparency, HDR and wide colour
- Decoded by every modern browser
Trade-offs
- Browser-side encoding is not universally available yet
- Rejected by many older apps, email clients and print services
- Slower to encode than JPG/WebP
