ARW (Alpha RAW) is Sony's proprietary RAW image format used by Alpha mirrorless and DSLR cameras. Based on TIFF structure, ARW stores unprocessed 12-bit or 14-bit sensor data, preserving maximum dynamic range and color information for professional post-production. ARW files include embedded JPEG previews and comprehensive EXIF metadata including lens corrections and Real-time Eye AF data.

ARW is the standard RAW format for Sony's popular Alpha series including the A7, A7R, A7S, A9, A1, ZV-E1, and FX series cinema cameras. For sharing or web publishing, conversion to JPEG is necessary since RAW formats require specialized software like Adobe Lightroom, Capture One, or Sony's Imaging Edge Desktop application.
WebP is Google's modern image format offering both lossy and lossless compression modes, plus alpha transparency and animation support—essentially combining the best features of JPEG, PNG, and GIF. Announced in 2010, WebP typically delivers 25-35% smaller files than JPEG at comparable quality using VP8 or VP8L compression. All major browsers now support WebP, making it a practical choice for web optimization.

WebP strikes an excellent balance between compression efficiency and ecosystem maturity. It's widely adopted for web delivery, supported across all modern browsers (Chrome 32+, Firefox 65+, Safari 14+, Edge 18+), and offers better compression than JPEG/PNG without the encoding overhead of AVIF.
CMS support: WordPress 5.8+ (July 2021) supports WebP natively. Most modern CMS platforms and CDNs (Cloudflare, Akamai, Fastly) can automatically serve WebP to compatible browsers via content negotiation.
Email limitation: Most email clients (Outlook, Gmail web, Apple Mail) do not support WebP. Always use JPG or PNG for email images, or provide a JPG fallback via <picture> elements in HTML emails.
