ORF vs WEBP
Ein detaillierter Vergleich von Olympus RAW ORF und WebP Image — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
WebP 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
ORF Vorteile
- Compact files relative to sensor size (Four Thirds is smaller than APS-C).
- Computational photography features (Live Composite, Pro Capture) baked into format.
- Stable across 20+ years of Olympus/OM SYSTEM bodies.
- In-body stabilization means ORF handheld shots rival tripod work.
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
ORF Einschränkungen
- Smaller sensor means less dynamic range than full-frame raws.
- Lossy compressed ORF is the default — hidden quality loss.
- Market share is small; fewer tutorials and fewer Lightroom profiles.
- Proprietary with no official spec.
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
ORF (Olympus RAW ORF) 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 ORF when its particular strengths match the publishing target.

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

Upload the ORF 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; ORF 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.
