Sobre los archivos PCXComparativa 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.
PCX Ventajas
- Simple format — easy to parse in any language.
- RLE compression keeps flat-color images compact.
- Historic archive format for 1985-1995 PC art.
- Stable since 1985 with no breaking changes.
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.
PCX Limitaciones
- Legacy — no new content created as PCX in 2026.
- Inefficient for photographs (RLE is wrong algorithm).
- Limited to 24-bit color depth.
- Web browsers do not display PCX.
