Resize Videos for TikTok, Instagram, YouTube, and More
Every social platform has its own video dimensions. TikTok and Reels want 9:16 vertical, YouTube prefers 16:9 landscape, Instagram feed uses 1:1 or 4:5. Shortify's social resizer lets you reformat any video for any platform with drag positioning and safe zone guides — all in your browser.
Upload a video, pick a target aspect ratio, drag to position the visible area, and export. One video in, every format out. No re-editing, no re-uploading.
How It Works
- Upload a video. Drag and drop any MP4, WebM, or MOV file.
- Choose an aspect ratio. 9:16 (TikTok/Shorts/Reels), 16:9 (YouTube), 1:1 (Instagram), 4:5 (Instagram feed), or custom.
- Position the frame. Drag the video within the crop area to choose what is visible. Safe zone overlays show where platform UI will cover content.
- Export. Download the resized video, processed in your browser.

- 16:9 — YouTube, Twitter/X, LinkedIn

Frequently Asked Questions
Yes. The multi-export feature lets you queue multiple aspect ratios and download all formats from a single source video.
Safe zones are the areas of the screen where platform UI elements (like buttons, usernames, and captions) appear. The resizer shows overlay guides so you can position important content outside these zones.
The resizer maintains the original video quality within the cropped area. No additional compression is applied beyond what the browser codec provides.
MP4, WebM, and MOV files are supported. Use the video converter if you need to change formats before or after resizing.
