Frequently Asked Questions
- How do I resize a video for Instagram or TikTok?
- Upload your video and set the dimensions to 1080x1080 for Instagram square posts, 1080x1350 for Instagram portrait, or 1080x1920 for TikTok, Reels, and Stories. Click Process to resize.
- Does resizing change the aspect ratio?
- If the new width and height have a different ratio than the original, the video will be stretched to fit. To maintain the original aspect ratio, scale only one dimension proportionally.
- Can I upscale a video to a higher resolution?
- You can set larger dimensions, but upscaling won't add detail — it simply stretches existing pixels. For best quality, resize to the original resolution or smaller.
