PEF vs WEBP
Ein detaillierter Vergleich von Pentax RAW und WebP Image — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
Pentax RAW
Raster & Vector ImagesPEF is the RAW image format used by Pentax DSLR cameras, containing full sensor data.
Über PEF-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
PEF Vorteile
- Full Pentax sensor data with 14-bit or 12-bit depth.
- Rich Pentax makernotes for lens and filter metadata.
- DNG alternative available on body — user choice of archival openness.
- Every major raw processor supports PEF.
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
PEF Einschränkungen
- Proprietary with no public spec.
- Niche market share — Pentax DSLR sales are a fraction of Canon/Nikon/Sony.
- Lightroom profile coverage trails the Big Three.
- Smaller third-party ecosystem.
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
PEF (Pentax RAW) 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 PEF when its particular strengths match the publishing target.

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

Upload the PEF 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; PEF 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.
