Best Video Formats for Social Media in 2026
Discover the optimal video formats, resolutions, and settings for Instagram, TikTok, YouTube, and other platforms.
Uploading videos to social media shouldn't be a guessing game. Each platform has specific requirements for format, resolution, and aspect ratio. Using the wrong settings can result in cropped content, poor quality, or failed uploads.
The Universal Standard: MP4 with H.264
If there's one format that works everywhere, it's MP4 with H.264 video codec and AAC audio. This combination is accepted by every major social media platform and provides excellent quality at reasonable file sizes.
Our free video converter can convert any video to this format automatically.
Platform-Specific Requirements
Instagram has different requirements for different placements:
| Placement | Aspect Ratio | Resolution | Max Length |
|---|---|---|---|
| Reels | 9:16 | 1080x1920 | 90 seconds |
| Stories | 9:16 | 1080x1920 | 60 seconds |
| Feed (Square) | 1:1 | 1080x1080 | 60 minutes |
| Feed (Portrait) | 4:5 | 1080x1350 | 60 minutes |
Pro tip: Instagram heavily compresses videos during upload. Starting with high-quality source material (bitrate of 3500-5000 kbps) helps maintain quality after compression.
