About formats

IIQ (Intelligent Image Quality) is the proprietary RAW format developed by Phase One), a Danish manufacturer of medium-format digital camera systems and backs, introduced in 2008 with the P65+ digital back. IIQ files capture the unprocessed readout from Phase One's large-area CCD and CMOS sensors — ranging from 40 to 151 megapixels in current systems — at 16 bits per channel, preserving the full dynamic range, color depth, and spatial resolution of the sensor. The format comes in two variants: IIQ Large (IIQ L), which uses lossless compression for zero-quality-loss archival, and IIQ Small (IIQ S), which applies visually lossless compression to reduce file sizes by approximately 40-60% with negligible quality impact. Phase One's sensor calibration data, including per-pixel defect maps, fixed-pattern noise profiles, and factory color calibration, is embedded in the IIQ file, enabling precise correction during RAW development. One advantage is sheer resolving power and tonal depth: IIQ files from Phase One's flagship systems deliver the highest pixel counts and widest dynamic range available in commercial photography, making them the standard format for museum digitization, fine art reproduction, aerial surveying, and commercial advertising where maximum detail is non-negotiable. Tight integration with Capture One is another key strength — Phase One develops both the camera hardware and the RAW processing software, ensuring that IIQ files receive optimized demosaicing, color rendering, and lens correction tuned to each specific camera-lens combination.

WebP is an image format developed by Google, announced on September 30, 2010, designed to provide superior compression for web images in both lossy and lossless modes. The lossy mode is derived from the VP8 video codec's intra-frame coding (the same technology used in WebM video), applying block prediction, transform coding, and adaptive quantization to photographic content. The lossless mode uses a distinct algorithm combining predictive coding, color space transforms, backward reference to repeated pixel patterns, and entropy coding. WebP also supports alpha transparency in both modes — lossy WebP with transparency is unique among common web formats, offering semi-transparent images at much smaller sizes than PNG. The format supports animated sequences as well, providing a modern alternative to GIF with full-color support and dramatically better compression. One advantage is substantial file size reduction — lossy WebP produces images 25-35% smaller than JPEG at equivalent visual quality, and lossless WebP is typically 26% smaller than PNG, directly improving web page loading speed and reducing bandwidth costs. Universal browser support provides another key strength: Chrome, Firefox, Safari, Edge, and all mobile browsers now render WebP natively, achieving the broad adoption threshold needed for practical deployment. Google's core web infrastructure (Search, YouTube thumbnails, Gmail) uses WebP extensively, and the format is supported by major CDN platforms, CMS systems, and image processing services. WebP has established itself as the primary modern alternative to JPEG and PNG for web content.

Frequently Asked Questions

Why convert IIQ to WEBP?

Phase One IIQ RAW files are too large and specialized for everyday use. Converting to WEBP produces practical files for sharing, editing, or publishing.

What opens WEBP?

Chrome, Firefox, Safari, Edge, and most modern image viewers support WebP natively.

Will the image quality be preserved?

The converter extracts full quality from IIQ RAW data and renders it into WEBP with the best possible fidelity for the target format.

Can I convert IIQ to WEBP on my phone?

Absolutely. The converter works in any mobile browser — iOS Safari, Android Chrome, or any other. No app installation necessary.

Is IIQ to WEBP conversion free?

Standard conversions are available at no cost. Premium plans add faster processing and higher limits for professional-volume work.
