Una comparativa detallada de AVIF Image y Windows Metafile — tamaño de archivo, calidad, compatibilidad y cuál elegir según tu flujo de trabajo.
AVIF Image
Raster & Vector ImagesAVIF is a next-generation image format based on the AV1 video codec. It offers significantly better compression than JPEG and WebP while maintaining excellent visual quality, including HDR and wide color gamut support.

Sobre los archivos WMFComparativa de ventajas
AVIF Ventajas
- Best-in-class compression efficiency — 30-50% smaller than JPEG for the same quality.
- Royalty-free and patent-unencumbered (unlike HEIC).
- Supports alpha transparency, HDR, wide gamut (BT.2020), and up to 12-bit color.
- Progressive decoding: a blurry preview appears while the file is still downloading.
- Supported in all major browsers since late 2022 — no polyfills needed.
WMF Ventajas
- Native Windows vector format.
- Efficient for line-art and diagrammatic images.
- Preserved in Office clipboard workflows.
Limitaciones
AVIF Limitaciones
- Encoding is CPU-expensive — an AVIF export can take 10-30× longer than JPEG.
- Older software (pre-2022) cannot open AVIF without plugins.
- Email clients still largely ignore it — stick to JPEG for attachments.
- Metadata support (EXIF, XMP) exists but tooling is less mature than for JPEG.
WMF Limitaciones
- Windows-only — poor Mac and Linux support.
- 2005 security vulnerability eroded trust.
- 16-bit coordinates in original WMF limit canvas size.
- Largely superseded by SVG for modern vector exchange.
- Not a web format.
