Use Cases
Compress Video for Any Platform
TikTok
TikTok recommends keeping uploads under 500 MB for best performance, though limits vary by account and region. Compressing your video reduces upload time and helps avoid processing issues or compression by TikTok itself.
Instagram Reels
Instagram supports videos up to 4 GB, but smaller files upload faster and maintain better quality after platform compression. Compressing before upload helps avoid quality loss and long processing times.
YouTube Shorts
YouTube Shorts supports videos up to 2 GB. Compressing your video helps reduce upload time and ensures smoother processing, especially for vertical 9:16 videos in high resolution.
FAQ
Frequently Asked Questions
