With KLEKSI, you can manage various types of media files and link them to objects. Via the integrated DAM (Digital Asset Manager) / File Manager, you can upload virtually any desired file type and subsequently register, describe, and present it.

To optimize storage space, data traffic, and loading times, images, audio, and video files are automatically processed into optimized versions. As a result, files load faster, less bandwidth is consumed, and the ecological footprint of your collection remains as small as possible.


Adding media files to an object
On the object management page, you can manage the media files linked to an object in the upper right corner.

1. Click on Add media file(s).
2. The DAM/File Manager is opened.
3. Select one or more files.
4. Click on Select File(s).

The selected files are added directly to the object.


Manage images
When an image is linked to an object, the following actions are available:

• Edit – Open the image editing tool.
• Change order – Move images to the desired position using drag & drop.
• File information – View the location of the original file in the DAM/File manager.
• Remove – Remove the image from the object.

When multiple images are linked, the order in which they are displayed determines the presentation within the object and on the frontend.


Image editing tool
With the built-in image editing tool, you can crop, rotate, and mirror images without modifying the original file.

Crop image

1. Click Edit on an image.
2. The image editing tool opens.
3. Drag the blue frame to determine the desired cropping area.
4. View the result in the preview.
5. Click Save.

KLEKSI then automatically generates a new derivative image based on your crop.

Other operations
In addition to cropping, you can image:

• Rotate counterclockwise
• Rotate clockwise
• Mirroring horizontally
• Mirror vertically
• Original file is retained

The original file in the DAM/File Manager is never modified or overwritten. Every edit results in a new derivative image that is automatically optimized for fast use within KLEKSI and on websites.

When you perform another edit later, the system starts again from the original file. This preserves image quality and allows you to easily generate multiple detail images from a single source file.


Audio and video files
KLEKSI automatically optimizes audio and video files for online use.

After uploading, videos are converted to various quality levels so that visitors always get the best possible playback experience without consuming unnecessary data traffic.

The following actions are available for audio and video files:

• Change order via drag & drop.
• Delete the file.

Video optimization
Videos are automatically converted into streaming files suitable for various internet speeds and devices.

Depending on the resolution of the source file, KLEKSI generates multiple derivative files. In addition, a preview image (poster) and a thumbnail are automatically created.

The standard quality levels are:

Resolution	Bitrate
1080p	6000 kbps
720p	3000 kbps
480p	1000 kbps
360p	600 kbps
240p	300 kbps

The actual settings are automatically adjusted to the source file.


Customization possible
Do you have specific requirements regarding video quality, file size, or very large video files? Then the conversion settings can be adjusted. This ensures that KLEKSI remains suitable for both small collections and extensive audiovisual archives.


Supported video files
KLEKSI supports all common video formats. In most cases, new file formats can be easily added when needed.

If a specific format is not yet supported, please contact the support department to discuss the possibilities.


PDF files
When you link a PDF file to an object, you can open it in the integrated PDF viewer.

The PDF viewer offers, among other things:

• Page view
• Zoom
• Navigating through the document
• Search within the entire PDF

This allows users and visitors to easily consult large documents without first downloading them.

3D files
KLEKSI supports the registration and presentation of 3D objects.

After mounting a supported 3D file, you can open it in the integrated 3D viewer. This allows objects to be viewed from all angles, zoomed in, and rotated.

Supported file formats include:

• STL
• OBJ
• GLTF
• CAP

This makes KLEKSI suitable for managing both physical collections and digital 3D reconstructions, scans, and models. If a specific format is not yet supported, please contact the support department to discuss the possibilities.
