This page provides tips to help you optimize your media files hosted on Publish.
#
Images
When uploading images directly to Publish, it's best to use .svg, .webp, and .png formats. We also recommend optimizing all images to reduce their file size while preserving visual quality.
If you're using an external service to host an image, we still recommend sizing the image as needed according to our embedding instructions.
#
PDFs
PDFs come in various sizes and complexities. To optimize the performance of embedded PDFs in Publish, we recommend compressing the files and removing any unnecessary images. Most PDF editors offer these capabilities.
#
Videos and audio
Publish is not optimized for hosting large videos, GIFs, or audio files. Embedding internally hosted and linked videos is not recommended if you plan to host numerous files of these types.
For hosting a limited number of files, we recommend using the following formats:
Video
.mp4.webm.hevcor.av1(Note: Not widely supported)
Audio
.aac.mp3.opus
