HDR vs TIFF
Ein detaillierter Vergleich von Radiance HDR Image und TIFF Image — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
Radiance HDR Image
Raster & Vector ImagesHDR (Radiance) stores high dynamic range images for realistic lighting in 3D rendering.
Über HDR-DateienTIFF Image
Raster & Vector ImagesTIFF is a flexible, high-quality image format widely used in publishing, printing, and professional photography. It supports multiple compression methods and color spaces including CMYK.
Über TIFF-DateienVorteilsvergleich
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.
TIFF Vorteile
- Lossless by default — no generation loss on successive edits and saves.
- Supports any bit depth (1 to 32 bits per channel), any color model, any number of channels.
- Extensible tag system means vendor-specific data survives alongside standard tags.
- Multi-page containers are perfect for scanned documents, faxes, and DICOM-like stacks.
- Industry-standard for archival, museums, scientific imaging, and high-end print prepress.
Einschränkungen
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.
TIFF Einschränkungen
- File sizes are huge compared to JPEG/WebP/AVIF — often 10-30× larger.
- Not a web format — no browser displays TIFF natively.
- Ambiguous spec areas mean some TIFFs only open correctly in the tool that created them.
- Weak animation support — designed for still imagery.

Häufig gestellte Fragen
HDR (Radiance HDR Image) is an image format used to store raster graphics — a two-dimensional grid of pixels describing a picture. It is part of the raster & vector images family and designed around a specific trade-off between file size, visual fidelity, and feature support (transparency, colour depth, compression type). Photographers, web designers, and content creators choose HDR when its particular strengths match the publishing target.

Most desktop photo viewers (Windows Photos, macOS Preview, GIMP, Photoshop, Affinity Photo) open HDR natively. On mobile, iOS Photos and Google Photos display HDR in the gallery when supported by the OS. If the format is rare or new, convert to JPG or PNG first — both are universally readable — using our HDR to JPG or HDR to PNG converter.

Upload the HDR to KaijuConverter and pick a target format (JPG, PNG, WebP, HEIC, TIFF, BMP, SVG, PDF). The conversion runs in the browser via ImageMagick and returns a download in seconds. No account or installation required; both input and output delete automatically within two hours.
It depends on the task. JPG is the smallest file size for photographs; PNG is lossless with transparency; HDR has its own niche that may favour colour depth, animation, or encoding efficiency over one or both of those. For the final web publish, test all three and measure file size plus visible quality on real content.
