AVIF vs HDR
Ein detaillierter Vergleich von AVIF Image und Radiance HDR Image — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
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.
Über AVIF-DateienRadiance HDR Image
Raster & Vector ImagesHDR (Radiance) stores high dynamic range images for realistic lighting in 3D rendering.
Über HDR-DateienVorteilsvergleich
AVIF Vorteile
- 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.
HDR Vorteile
- True floating-point dynamic range in 32 bits per pixel.
- Simple format — easy to parse and generate.
- Standard for environment maps and lighting probes in 3D.
- 30+ years of continuous use in architectural rendering.
Einschränkungen
AVIF Einschränkungen
- 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.
HDR Einschränkungen
- No compression — files are larger than OpenEXR or AVIF for equivalent quality.
- Only one channel set (RGB) — no alpha, no multi-layer like EXR.
- Not a web format.
- Aging — OpenEXR is the modern professional choice.

AVIF files open in Chrome, Firefox, Safari (from macOS Ventura), Edge, and GIMP 2.10+. Support is growing rapidly, but some older image editors may not yet handle AVIF natively.

AVIF provides better compression and quality than WebP, especially for photographs. However, WebP has broader software support today. Use AVIF for maximum performance on modern browsers and WebP as a reliable fallback.
