Frequently Asked Questions
- Why does TikTok always zoom in on my video?
- TikTok requires a strict 9:16 aspect ratio (1080x1920). If you upload a 1:1 or 4:5 video, it stretches to fill the screen. Use this tool to check compatibility first.
- What is the best resolution for Instagram Reels?
- 1080 x 1920 pixels. This is the native 9:16 format. Avoid 4K as compression often reduces quality.
- Can I convert landscape (16:9) to vertical (9:16)?
- Yes, but you will lose the sides of your video (cropping). Use the calculator above to see what the new cropped dimensions would be.
- What happens if I upload 16:9 to Instagram?
- On the feed, it looks tiny. On Reels, it gets black bars. It's highly recommended to use 4:5 for posts and 9:16 for Reels.
- Is this tool safe to use?
- Yes! All processing happens locally in your browser. Your images are never uploaded to any server.
