ARW vs WEBP
Un confronto dettagliato tra Sony RAW ARW e WebP Image: dimensioni del file, qualità, compatibilità e quale formato scegliere per il tuo flusso di lavoro.
Sony RAW ARW
Raster & Vector ImagesARW is Sony Alpha RAW format for professional and mirrorless cameras.
Informazioni sui file ARWWebP 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.
Informazioni sui file WEBPConfronto dei punti di forza
ARW Punti di forza
- Full 14-bit sensor data on flagship bodies.
- Rich Sony metadata (Creative Style, DRO, Focus Magnifier).
- Supported by every major raw processor.
- Lossless compression available on modern bodies.
WEBP Punti di forza
- 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.
Limitazioni
ARW Limitazioni
- Proprietary — new Sony body launch = Lightroom update required.
- Lossy compression was the only option on many older bodies (visible banding in highlights).
- File sizes are huge on 50+ MP bodies.
- Some ARW variants use 16-bit layout that breaks older third-party tools.
WEBP Limitazioni
- 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.
