EXR to EPS Converter

Encoding: the EXR uses none, RLE, ZIP, PIZ, PXR24, B44 or DWA, chosen per file; EPS uses PostScript program text, with an optional binary TIFF preview or an EPSI hex preview, and the download is an EPS that wraps the pixels as a PostScript image; it contains no vector paths.

Bit depth: 16-bit half or 32-bit floating point per channel in the EXR; EPS allows resolution-independent artwork, with previews usually 8-bit, and the EPS written here has 8 bits per channel. 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; EPS supports CMYK, RGB and spot colours, written here as 8-bit sRGB.

Transparency: the EXR stores it as an A channel stored like any other channel; the EPS has none, so transparent areas are filled with the colour you choose.

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; EPS can carry DSC comments such as %%BoundingBox, %%Creator and %%Title, 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.

EPS is a PostScript drawing packaged for placing inside other documents. It was the exchange format of print and logo design for decades; most EPS files also carry a raster preview so layout software can show them.

An EPS is a PostScript program with DSC comments ('%!PS-Adobe-3.0 EPSF-3.0', %%BoundingBox). Files from Illustrator, Photoshop and CorelDRAW usually start with a 30-byte binary header (C5 D0 D3 C6) that points to a TIFF preview; others carry an EPSI hex preview between %%BeginPreview and %%EndPreview.

EPS is the better choice for print artwork and logos for professional layout software, while EXR suits visual effects, compositing and 3D render output.

EPS strengths: Vector artwork that prints at any size; Accepted by print shops and older layout software; CMYK and spot colours. Drawbacks to weigh: Browsers and phones cannot display it; Needs a PostScript interpreter to render the vector data; Superseded by PDF and SVG.
