The list below includes all current file types that generate 100% accurate previews in Vault. If you notice anomalies in the way your file is displayed (e.g. color saturation, washed out) or see an icon instead of a preview, refer to this list to see if it is supported. Please note that some CMYK files may not display as expected, depending on your browser. 


If the file is on the list of supported previews but is not displaying correctly, please email us at info@tandemvault.com so that we can reprocess your asset. Remember to include a link to the asset(s) for swifter resolution.

Common file types that do not currently generate previews:

  • WAV: This is an audio file, so it does not produce a visual.
  • ZIP: This is usually a collection of files, so there is no single document to preview.
