IIQ to JPEG Converter

IIQ (Intelligent Image Quality) is the proprietary raw image format used by Phase One digital cameras and digital backs, primarily medium format systems used in professional photography.

This format stores the unprocessed data directly from the camera's image sensor, preserving the maximum amount of information for post-processing flexibility.

IIQ files typically contain significantly more color information and dynamic range than processed formats like JPEG, allowing for extensive adjustments to exposure, white balance, and color without quality degradation.

Phase One offers two variants: IIQ L (Large) which uses lossless compression and IIQ S (Small) which uses lossy compression while still maintaining very high quality, giving photographers options based on their storage and workflow needs.

IIQ files can be opened with Phase One's Capture One software, which is specifically designed to process these raw files with maximum quality and control.

Adobe Camera Raw and Lightroom support IIQ files from supported Phase One cameras, offering an alternative workflow for photographers already using Adobe's ecosystem.

Other professional raw processing applications like DxO PhotoLab, ON1 Photo RAW, and Exposure X may support IIQ files from certain Phase One camera models.

For preview purposes, some general image viewers and operating systems may display the embedded JPEG preview in IIQ files, but cannot access or process the raw data itself.

To convert IIQ files to more widely compatible formats like TIFF, JPEG, or PNG, use our specialized raw converter that preserves the image quality while making it more accessible.

For the highest quality processing and conversion, Phase One's Capture One software offers advanced tools specifically optimized for IIQ files with precise control over all aspects of the image.

When converting from IIQ to other formats, consider 16-bit TIFF for maximum quality retention or DNG (Digital Negative) format to maintain raw processing capabilities in other software.

For web sharing or client previews, converting to standard formats like JPEG with appropriate color space selection (sRGB for web use) ensures proper display across different devices.

JPEG (Joint Photographic Experts Group) is a widely used image format known for its excellent compression capabilities without compromising visual quality. This format is perfect for photographs and web images, as it significantly reduces file size, making it ideal for online use and sharing. Supported extensions include .jpg and .jpeg.

JPEG files are compatible with almost every device and platform, making them a universal choice for image storage and sharing. They are especially suited for digital photography and web graphics, maintaining a balance between quality and file size. Use JPEG for efficient and visually appealing image storage.

Opening JPEG files is straightforward as they are supported by almost all image viewers and editors. On Windows, you can use the built-in Photos app or third-party software like Adobe Photoshop. On Mac OS, Preview is a default application that handles JPEG files seamlessly.

For Linux users, applications like Shotwell or GIMP can be used to open and edit JPEG images. Additionally, web browsers such as Chrome and Firefox can display JPEG files directly. If you encounter issues opening JPEG files, ensure your software is up-to-date or try a different viewer.

Converting JPEG files is easy with our online converter. Whether you need to change the format for better compatibility or reduce the file size, our tool offers quick and free conversion. Simply upload your JPEG image, select the desired output format, and click convert.
