Platform Media Limits

Learn about the media upload limits for Twitter, Facebook, Instagram, LinkedIn, TikTok, and YouTube when creating posts.

Home › Help Center › Platform Guides › Platform Media Limits

Each social media platform has specific limits on how many images or videos you can include in a single post. ACE AI Spark enforces these limits automatically during upload to prevent publishing errors.

Platform Limits

Platform	Max Images	Max Videos	Notes
X (Twitter)	4	1	4 images or 1 video per tweet — cannot mix.
Facebook	10	1	Up to 10 images or 1 video per post.
Instagram	10	1	2–10 items for carousel posts. Single image or video for standard posts.
LinkedIn	9	1	Up to 9 images or 1 video per post.
TikTok	1	1	Publishing requires video. Photo mode supports images but video is primary.
YouTube	—	1	1 video per upload only. No image posts.

Important Rules

No mixing: You cannot combine images and videos in the same post on any platform. File size limits: Images up to 50 MB, videos up to 2 GB per file. See File Upload Limits for full details. Cross-platform posting: When posting to multiple platforms simultaneously, ACE AI Spark applies the most restrictive limit. For example, if you post to both Twitter (max 4 images) and Instagram (max 10), you'll be limited to 4 images.

Best Practices

🎯 Check limits before uploading

Review the platform limits above before attaching media to avoid upload rejections.

📐 Optimize for each platform

Different platforms prefer different aspect ratios. Square (1:1) works well across most platforms.

🔄 Use platform-specific posts

For maximum flexibility, create separate posts per platform instead of cross-posting when media needs differ.
