Change the Preview/Thumbnail of an Asset

  • ~ minute read

Open an Asset > Change Thumbnail

With Canto, you are able to change the preview of an asset. This is helpful to replace the preview image for, either files that don't have a preview image (e.g. Zip-files) or files that display a low-quality preview due to file conversion  (e.g. TIF-files). 

Note: The new preview/thumbnail  needs to be an image file (PNG, JPG, or JPEG). Image files must use the same aspect ratio as the original file when replacing the thumbnail. You can still use a different orientation but the crop will be restrained. For Video, Audio, Documentation, Presentation, etc. are not required to retain the aspect ratio of the original file.
