Options for rendering PDFs and other multi-page file formats (such as Adobe Illustrator files). For an in-depth tutorial, see Managing Brand Assets from PDFs.
PDF Rendering Behavior
Any parameter (default parameters included) will cause PDFs to go through our renderer. When this happens, imgix will rasterize the file and serve only a single page from any PDF. Suppose you want to serve a PDF in its original format with all its pages. In that case, we recommend either serving the PDF with no imgix parameters applied or using fm=pdf.
The only exception is the download parameter, which will allow users to download the full, unmodified file.
