About PNG → AVIF
Why convert PNG to AVIF?
AVIF produces dramatically smaller files than PNG for the same image, which is the main reason to convert. AVIF currently offers the best compression of any mainstream image format, ideal for performance-critical websites.
About PNG
PNG is a lossless image format built around exact pixel preservation and a real alpha channel. It excels at flat graphics, UI screenshots, logos, icons and any image that has to look pixel-perfect or sit on top of another background. Because every pixel is stored exactly, PNGs are much larger than JPG or WebP for the same photo content.
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.

PNG is a lossless image format built around exact pixel preservation and a real alpha channel. It excels at flat graphics, UI screenshots, logos, icons and any image that has to look pixel-perfect or sit on top of another background. Because every pixel is stored exactly, PNGs are much larger than JPG or WebP for the same photo content.
Strengths
- Lossless — never degrades when re-saved
- Full alpha-channel transparency
- Universal browser and OS support
Trade-offs
- Much larger files than JPG/WebP/AVIF for photos
- No animation (APNG exists but is rarely used)
- Slower to encode than JPG on large dimensions

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
