EXR to SVG Converter

Encoding: the EXR uses none, RLE, ZIP, PIZ, PXR24, B44 or DWA, chosen per file; SVG uses XML text describing paths, shapes and text, sometimes gzipped as .svgz, and the download is an SVG traced into vector paths (or, if you prefer, the pixels embedded in an SVG wrapper).

Bit depth: 16-bit half or 32-bit floating point per channel in the EXR; SVG allows not fixed: coordinates and colours are continuous values, and the SVG written here has vector paths with flat colours. Floating-point values are mapped to 8 bits per channel, and anything brighter than white clips.

Colour: scene-linear RGB, often ACEScg or linear Rec.709 in the EXR; SVG supports sRGB by default, other spaces through CSS colour functions, written here as flat colour regions.

Transparency: the EXR stores it as an A channel stored like any other channel; the SVG keeps it as opacity on any element, with anti-aliased edges.

Other images: the EXR can hold extra channels (depth, normals, render passes) and multiple parts; only the main image is converted.

Metadata: the EXR can carry named header attributes such as chromaticities, timecode and camera data; SVG can carry title, description and RDF metadata elements, but nothing is copied across.

OpenEXR is the high dynamic range format of film visual effects. It stores half or full floating-point channels in linear light, plus any extra render passes, and is the working format of compositing pipelines.

An EXR starts with the magic number 76 2F 31 01 and a version field, then a header of named, typed attributes (channels, compression, dataWindow, displayWindow) and a table of offsets to scanline or tile blocks.

EXR files usually come from 3D renderers and compositing in Nuke, Blender, Houdini, After Effects and DaVinci Resolve.

SVG describes shapes, paths and text as XML instead of pixels, so it stays crisp at any size. It is the standard for logos, icons and illustrations on the web.

An SVG is an XML document: a root <svg> element with a viewBox, then paths, shapes, text, gradients and filters. It can also embed raster images and, dangerously, scripts, which is why untrusted SVG is sanitized before rendering here.

SVG is the better choice for logos, icons and illustrations, while EXR suits visual effects, compositing and 3D render output.

SVG strengths: Infinitely scalable and sharp; Tiny files for logos and icons; Editable as text and styleable with CSS. Drawbacks to weigh: Not suitable for photographs; Can contain scripts, so untrusted SVG must be sanitized; Many apps and social sites will not accept it.
