PIX recommends preparing images, documents, and audio files to the specifications below. Following these recommendations will ensure that your media loads quickly and will be streamable across all PIX platforms.
If you are looking for video preparation specs, those recommendations can be found on this help page: Prepare Video Media for PIX.

We recommend creating images in the following formats:
We recommend keeping image sizes below 5000 x 5000 pixels.
There is a size limit of 500MB or 100 megapixels (ex: 10,000 x 10,000). Images that exceed this limit cannot be viewed in PIX, are not watermarked, and do not have preview thumbnails.
We also recommend using RGB color for your images. However, Gray, Index, and Lab are also supported. If you post images with CMYK color, it may affect the color of the overlaying watermark.
Notes regarding image support on PIX:
PIX Supports the viewing of PDFs only. In order to ensure your PDF is viewable in PIX, please be sure to check the following:
Other document types can be uploaded to PIX in a zip file and distributed for download if necessary.

We recommend creating AAC audio files. We also support WAV, AIFF, BWF, SND, MP3, MP4, M4A, and AU files.

If you need to distribute assets that are not supported for viewing in PIX, you can upload zipped content to PIX and use our Share for Download feature to transfer files securely within the system.
