Recommended size for media files uploaded to the bot

The official limitation is 23,8 Mb - however, we strongly recommend using files of a smaller size (preferably 10 Mb or less), because the files can become much bigger after encoding on Facebook's side.

Here are some helpful tips:

  1. Downsampling your video to standard web sizes (no HD) 
  2. Compressing video and changing file type from .mp4 to .mov
  3. Change dimensions of the video down to a smaller size (the perfect dimensions would be 270x480)
  4. Using MP3s instead of AAC or WAV
  5. Using optimized JPEGs instead of RAW or PNG24
  6. Keeping your animated GIF files to less than 10 seconds in duration

Hope that helps!
