How to Convert Video for Instagram Reels and TikTok
Social platforms have strict codec and dimension requirements. Convert once and upload without rejection errors.
Instagram Reels and TikTok reject uploads that use unsupported codecs, wrong aspect ratios, or oversized files. Converting before upload saves time and frustration.
Platform Requirements
- Instagram Reels: 9:16 aspect ratio, MP4 with H.264 codec, max 90 seconds
- TikTok: 9:16 recommended, MP4 or MOV, up to 10 minutes
- File size: Keep under 100 MB for smooth mobile uploads
Conversion Steps
Start with our MP4 to MOV or Video Compressor to meet size limits. Use Video Trimmer to cut clips to the right duration before uploading.
Pro tip: Film in vertical 1080x1920 from the start. Converting horizontal video to vertical crops out most of the frame.
Quality Check Before Posting
Preview the converted file on your phone. Check audio sync, text readability, and whether compression introduced visible artifacts.
Audio Tips for Social Video
Platforms normalize audio levels automatically. Export at a consistent volume rather than maximizing loudness. If your clip has music and voiceover, verify both are audible after compression - aggressive video compression can affect audio bitrate too.
Key Takeaways
- Shoot vertical 9:16 when possible
- Keep files under 100 MB for reliable mobile uploads
- Trim and compress before uploading to Reels or TikTok
