Assets file format best practices

Adobe Experience Manager Assets supports many proprietary and third-party file format libraries to cater to diverse file support requirements of users. The supported Adobe libraries include, Adobe Camera Raw, Gibson, Adobe PDF Rasterizer, and Adobe InDesign Server. In addition, Experience Manager Assets supports third-party libraries, including ImageMagick, TwelveMonkeys, and so on.
For the supported file formats, see Assets supported formats .
If you are using Experience Manager on Adobe Managed Services (AMS), reach out to Adobe Customer Care if you plan to process lots of large PSD or PSB files. Work with Adobe Customer Care representative to implement these best practices for your AMS deployment and to choose the best possible tools and models for Adobe's proprietary formats. Experience Manager may not process very high-resolution PSB files that are more than 30000 x 23000 pixels.

Adobe Camera Raw library

For optimal performance, Adobe recommends using Adobe Camera Raw library for RAW and DNG files.
Adobe Camera Raw library supports CMYK color profile as input. However, it generates the output in RGB colorspace and supports output in JPEG format only. It does not retain the source file colorspace (for example CMYK) in the thumbnails.
For more information, see Camera Raw support .

Adobe PDF Rasterizer library

For best results, Adobe recommends using the Adobe PDF Rasterizer library for the following files:
  • Heavy, content intensive PDF files
  • AI files with thumbnails not generated out of the box
  • For AI files with SPOT (PMS) colors
Thumbnails and previews generated using PDF Rasterizer are better in quality compared to out-of-the-box raster output. The Adobe PDF Rasterizer library does not support any colorspace conversion. Irrespective of the colorspace of the source PDF file, Adobe PDF Rasterizer generates only RGB output.

Adobe InDesign Server

Adobe recommends that you use Adobe InDesign Server to extract Adobe InDesign-specific renditions, such as IDML and HTML. For more information, see Adding Experience Manager assets as references in Adobe InDesign .

Dynamic Media

Dynamic Media generates and delivers multiple variations of rich content in real time through its global, scalable, and performance-optimized network. It serves interactive viewing experiences and streamlines the digital campaign management process. For details around enabling Dynamic Media, see Configuring Dynamic Media .
Currently, Dynamic Media can support videos up to 15 GB of content per file.

ImageMagick library

Adobe recommends using the ImageMagick library in the following scenarios:
  • To generate thumbnail renditions for EPS files.
  • To preserve image profile information.
  • To preserve transparency.
  • To process PSD and PSB files.
To know how to set up the ImageMagick library in Experience Manager, see Using ImageMagick . For optimum usage, see Best Practices for Configuring ImageMagick .

Image Transcoding Library

The Adobe Imaging Transcoding Library is an image-processing solution that performs core image-handling functions, including image encoding, transcoding, re-sampling, resizing, and so on.
Imaging Transcoding Library supports the following MIME types:
  • JPG/JPEG
  • PNG (8 bit and 16 bit)
  • GIF
  • BMP
  • TIFF/Compressed TIFF (apart from 32 Bit Tiffs and PTiffs).
  • ICO
  • ICN
