All Libris accounts support image files. Depending on your organization's Libris subscription type, Libris can also handle additional types of files and formats, such as video, audio, or other files.
- File formats determine what kind of software can be used to preview or work with a file. For example, Adobe Lightroom handles many image file formats, but cannot work with audio files
- The easiest way to know a file’s format is to look at the file extension, the characters after the last period at the end of the filename
- For example, the file baseball-game.jpg has a file extension of .jpg, which means it’s a JPEG, a specific type of image file
- It’s important not to edit or remove the file extension for your files, if you know the extension is accurate
- For example, if you changed the filename of baseball-game.jpg to baseball-game.mp3 (an audio file extension), or removed the extension entirely so the file was named just baseball-game, your computer might have trouble knowing what software program to use for that file, and you may not be able to open it correctly
When you upload a file to Libris, Libris detects the file type and format automatically. Libris sorts files into 4 different categories based on file type and format:
Libris supports many image file formats, such as:
- JPG, JPEG
- TIFF, TIF
- HEIF, HEIC
- Camera raw photos: most proprietary raw formats, such as CR2 and NEF, and any raw file converted to DNG
Libris offers more limited support for other files in this category:
- Only the 1st page can be previewed in Libris
- Protected PDFs, such as those with a password, are not supported
- No playback is available within Libris, so GIFs will render as a static image. If downloaded, a GIF can be played back.
- Libris generates an image preview of an EPS file’s contents
- Because this image is adjusted for web display, the image may not look exactly like the original EPS file
- SVG files that contain HTML will render as images
- Libris generates an image preview of some SVG files’ contents:
- Font files, such as DFONT, OTF, and TTF
- Libris generates an image preview for some font files, but does not support previews for all fonts

If your subscription supports video, Libris can handle many video file formats, such as:
- HEVC-encoded video files
- Other common video files from DSLR and other cameras, or those created by video editing software
- Full video support can depend on many factors, such as a video’s frame size, frame rate, data rate, codec, and other factors
- The general rule of thumb is: if it uploads and displays as a video file, we support it.
- Drone videos can vary in formatting and can often be missing the metadata that our video processors require to upload the files and store them correctly. If you have upload issues unrelated to your Internet connection, try to run the video through a program like Adobe Media Encoder or Adobe Premiere Pro (or any video encoding software) and re-export it. Usually, this will apply the required metadata on the files and resolve any upload issues. If the issues persist, please reach out to our Support team at email@example.com.
