Instagram Video Requirements
Instagram supports several video formats. Feed videos can be 3-60 seconds (or up to 60 minutes for IGTV). Reels are 15-90 seconds. Stories are up to 15 seconds per clip. The recommended resolution is 1080x1920 (9:16 aspect ratio) for Reels and Stories, and 1080x1080 (1:1) or 1080x1350 (4:5) for feed posts. MP4 format with H.264 codec is recommended.
How to Compress Video for Instagram
Upload your video, use our trimmer to cut it to the appropriate length (15s for Stories, 60s for Reels), then compress with the 'Best Balance' preset. The tool will reduce the file size while maintaining Instagram-quality resolution. For vertical content, ensure your video is already in 9:16 aspect ratio before uploading.
Optimizing Video for Instagram Reels
Instagram Reels perform best with vertical 9:16 videos at 1080x1920 resolution. Keep your Reel between 15-90 seconds. Use the 'Best Balance' compression preset to maintain quality while reducing file size. Add captions within Instagram after uploading, as the platform's built-in captioning is optimized for mobile viewing.
Instagram Stories Video Tips
Stories must be 15 seconds or less per clip. If your video is longer, our trimmer can split it into multiple 15-second segments. Compress each segment with the 'Smallest File' preset for fastest upload. Stories support both vertical 9:16 and horizontal 16:9 formats, but vertical performs better.
