How do I convert a PUB file to EXR?

Upload your PUB document to the converter, choose EXR as the output format, and adjust optional settings like DPI (default 300), transparency, and color space. Click 'Convert'. The tool will rasterize each page into a separate EXR image, downloadable as a ZIP if multiple pages exist. For best results, embed all fonts in the PUB file before uploading.

Why convert PUB to EXR instead of keeping PUB?

EXR is a professional high-dynamic-range image format used in VFX and compositing. Unlike PUB, which is a page-layout document, EXR supports 32-bit floating-point channels, lossless compression, and alpha transparency. Converting allows you to import your design directly into software like Nuke, After Effects, or Blender without losing color depth. It also makes the file viewable in image tools without Microsoft Publisher.

What happens to text, vector graphics, and layers during conversion?

The PUB page is flattened into a single EXR layer. Text and vector shapes are rasterized at the chosen DPI, so they become pixel-based. Transparency (alpha channel) is preserved if the PUB page has a transparent background. Multiple layers in the original PUB file are merged, but each page in the document becomes a separate EXR image. Color profiles are converted to sRGB unless you select linear in advanced options.
