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
- 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:
- 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
Recommended video settings:
Resolution: 640px to 3840px (4K) wide
Bitrate: 10 to 60 Mbps
Framerate: 15-60 FPS (constant)
Aspect ratio: 16:9
File size: up to 40 GB
Videos can be uploaded via the Contributor web uploader or incoming FTP. If the Libris subscription you are contributing to does not offer full file support, your file will not upload.
If your subscription offers full file support, Libris can handle many audio file types, such as:
- MP4, M4A
- AIFF, AIF
Recommended audio settings:
Sample Rate: 44.1 kHz
Audio files can be uploaded via the Contributor web uploader or incoming FTP. If the Libris subscription you are uploading to does not offer full file support, your file will not upload.
If your subscription offers full file support, Libris can handle many other non-media file types and formats, such as:
- INDD and other Adobe InDesign files
- DOC, DOCX
- XLS, XLSX
- PPT, PPTX
- ZIP: will stay zipped upon upload
- Other miscellaneous file types
- Note: HEIF files, such as those created on an iPhone 7 (or later model) running iOS 11, are currently processed by Libris as non-image files. If you are interested in changing your iOS settings to capture images as JPGs instead of HEIF/HEIC, you can learn how to change your iOS Camera settings here.
These file types can be uploaded via the Library Contributor web uploader and incoming FTP. Libris does not offer previews for these file types when your organization receives them.
