Image and video media formats, size limits, and other requirements for Facebook, Instagram, LinkedIn, YouTube, Google Business Profile, Pinterest, Telegram, TikTok, X/Twitter, & Reddit
Image and Video Posting Requirements
When publishing a post to the social networks, it is important to follow each network’s requirements. By following these guidelines, you can ensure your post is accepted by the social networks and reaches the intended audience.
Please see the post endpoint for additional details.
Accepted File Types
Files have an accepted file ending type (extension), such as jpg, jpeg, png, webp, gif, mp4, mov, or avi, with content-types such as image/jpeg or video/mp4.
If the media URL has special characters, e.g. ñ, please encode the special characters before sending.
Please see below for details on each network.
Maximum Images
Max images accepted per platform in a single post:
Facebook Pages: 10 images, including a carousel post.
- Instagram: 10 images.
- Google Business Profile: 1 image.
- LinkedIn: 9 images.
- Pinterest: 1 image.
- Reddit: 1 image.
- Telegram: 1 image.
- TikTok: 35 images.
- X/Twitter: 4 images.
Maximum Videos
Only one video is allowed per post for X/Twitter, Facebook, LinkedIn, Instagram, Pinterest, TikTok, YouTube, and Telegram. Reddit does not yet support videos.
Please be sure your video URL ends in an accepted video extension such as .mp4 or .mov, depending upon the network.
For example:
- Accepted:
https://mysite.com/video.mp4 - Not Accepted:
https://mysite.com/video.mp4?code=30s93
If your video is a signed URL or cannot end in an accepted video extension, you can use the isVideo parameter when publishing the post.
We recommend for larger video files over 50 MB create a scheduled post with the scheduleDate parameter for async processing.
Be sure to also check the upload speed of your media URLs to prevent timeouts at the social networks. If the media file cannot be downloaded within approximately 5 minutes a time out will likely occur.
