EXR vs WEBP
Ein detaillierter Vergleich von OpenEXR Image und WebP Image — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
OpenEXR Image
Raster & Vector ImagesOpenEXR is a high dynamic range imaging format used in visual effects and film production.
Über EXR-DateienWebP Image
Raster & Vector ImagesWebP is a modern image format developed by Google that provides superior lossless and lossy compression. Files are typically 25-35% smaller than equivalent JPEG or PNG images at the same visual quality.
Über WEBP-DateienVorteilsvergleich
EXR Vorteile
- Genuine high-dynamic-range storage (32-bit float per channel).
- Multi-channel layers native — store an entire render pass in one file.
- Industry standard across every major VFX and animation studio.
- Deep samples enable modern compositing workflows.
- Open-source reference implementation with mature tooling.
WEBP Vorteile
- Smaller file sizes than JPEG, PNG, and GIF at equivalent visual quality.
- Single format for lossy photos, lossless graphics, transparency, and animation.
- Full alpha channel support with smaller files than PNG.
- Now universally supported in all modern browsers.
- Open-source reference implementation (libwebp) by Google.
Einschränkungen
EXR Einschränkungen
- Enormous file sizes.
- Not a web format — browsers don't display EXR.
- Decoding is CPU-intensive.
- Consumer apps rarely need HDR at this precision.
WEBP Einschränkungen
- Some older software and image editors still don't read WebP natively.
- Max dimensions are 16,383 × 16,383 — lower than JPEG or PNG.
- Print workflows rarely support WebP (no CMYK, limited color management).
- Editing tools are less mature than JPEG/PNG; round-tripping can lose quality.

Häufig gestellte Fragen
EXR (OpenEXR 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 EXR when its particular strengths match the publishing target.

Most desktop photo viewers (Windows Photos, macOS Preview, GIMP, Photoshop, Affinity Photo) open EXR natively. On mobile, iOS Photos and Google Photos display EXR 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 EXR to JPG or EXR to PNG converter.

Upload the EXR 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; EXR 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.
