We have improved the preview image rendering and added new file formats to the list of supported formats. The following file formats now also get previews: .CR3 (Canon Raws), .HEIC (iPhone) .PSB (large Photoshop files) and .NEF (Nikon Raws). Also, the performance of creating previews of large GIF files after uploading has been improved. As always, you can find the complete list of supported formats on our website.
