EXR to JPG Converter

EXR (OpenEXR) is a high-dynamic-range image format built for visual effects work, storing far more brightness detail per pixel than a standard photo format.

Industrial Light & Magic built OpenEXR in 1999 for its own film pipeline and open-sourced it in 2003, and it's since become the de facto standard for handing rendered or scanned frames between VFX and animation studios. Where a JPG or PNG clamps every pixel to a fixed brightness range, EXR stores color as 16- or 32-bit floating-point values, so a blown-out sky or a shadowed doorway both keep real data an artist can pull back in compositing rather than pixels that were already thrown away at capture time. That flexibility comes at the cost of file size and near-universal absence from consumer software — it's a working format for VFX and 3D tools, not something a photo viewer or browser will open.

JPG (or JPEG) is the format most cameras and phones save photos in by default — it uses lossy compression tuned for photographic detail.

JPEG (Joint Photographic Experts Group) works by discarding image detail the human eye is least likely to notice, which is why it can shrink a photo to a fraction of its uncompressed size while still looking sharp at normal viewing sizes. That efficiency, combined with support baked into virtually every camera, phone, browser, and operating system since the early 1990s, made it the default photo format for the web and for personal photo libraries alike. The tradeoff is that JPEG is lossy: every time a file is re-saved, a little more detail is discarded, and it has no support for transparency, so it's a poor fit for logos or graphics that need to sit on any background.
