Preview Your Video in Any Aspect Ratio
Creating content for multiple platforms? Each social media platform has its preferred aspect ratio, and what looks great on YouTube might be awkward on TikTok. This Video Aspect Ratio Preview Tool lets you instantly see how your video will appear in different formats—before you spend time editing.
Simply upload your video, select an aspect ratio, and see exactly how your content will be cropped on each platform. Drag to reposition and zoom to find the perfect frame.
đź’ˇ From my experience: I used to edit a video for YouTube, export it, then realize it looked terrible when cropped for Instagram Reels. Now I preview every video before editing. Saves hours of re-work and ensures important elements stay in frame across all platforms.

Multi-Platform Repurposing Workflow
Here's a professional workflow for creating content that works everywhere:
Step 1: Film with Cropping in Mind
Keep important action in the center third of your frame. This ensures nothing critical gets cropped when converting from 16:9 to 9:16. Never put text or faces near the edges.
Step 2: Preview Before Editing
Use this tool to check all target aspect ratios before opening your video editor. Identify problem shots early.
Step 3: Edit Your Master Version
Create your main video in 16:9 (or your primary format), knowing which parts will need adjustment for other ratios.
Step 4: Create Platform Exports
Export different versions for each platform, adjusting crop and zoom as needed.
Common Aspect Ratio Mistakes
- Ignoring safe zones: TikTok and Instagram have UI elements that cover parts of your video
- Center-only framing: Not leaving room for cropping in different directions
- Text at edges: Gets cut off when ratio changes
- Forgetting thumbnails: YouTube thumbnail is 16:9, don't upload vertical content and expect good thumbnails
- Stretching instead of cropping: Never stretch video—always crop or add bars
Using the Grid and Safe Zone Overlays
Rule of Thirds Grid
The grid divides your frame into 9 sections. Place key subjects at the intersection points for visually pleasing composition.
Safe Zone Overlay
The yellow dotted border shows the "safe zone"—content here is guaranteed to be visible on all devices and won't be covered by platform UI elements.
