Video Aspect Ratio Resizing instantly reformats your video from one aspect ratio to another. Create a video in 16:9 (landscape) and instantly convert it to 9:16 (portrait), 4:5 (Instagram), or 1:1 (square)—all in seconds, with one click.
Each platform demands different aspect ratios. TikTok wants 9:16 vertical. YouTube wants 16:9 widescreen. Instagram wants 4:5 or square. Rather than editing the same video four times, you edit once and reformat instantly.
Our tool uses smart scaling and intelligent fill options (smart crop, zoom, blur fill) to adapt your video to any ratio without distortion or black bars. Plus split layouts let you upload a second video to create dual-video layouts (perfect for comparison videos, side-by-side gameplay, reaction videos, etc).
Most creators only post to one platform because reformatting is a nightmare:
Result: A 10-minute video editing session turns into a 2-3 hour multiformat publishing marathon. So creators just post to one platform and leave massive audiences untouched.
Video Aspect Ratio Resizer changes this. Edit once, export to 4 formats instantly. 2 hours becomes 10 minutes.
Step 1: Create Your Video — Edit your video in Bytecap in any aspect ratio. Doesn't matter if it's horizontal, vertical, or square.
Step 2: Select Target Formats — Choose which aspect ratios you want: 9:16 (TikTok), 16:9 (YouTube), 4:5 (Instagram), 1:1 (Square). Pick one or all four.
Step 3: Choose Fill Method — Select how to adapt: Smart Crop (auto-center), Zoom (fill entire frame), Blur Fill (blur background), or Full Fill (show black bars).
Step 4: Split Layout (Optional) — For split layouts, upload a second video. Bytecap positions both videos side-by-side, top-bottom, or in custom layouts.
Step 5: Export All Formats — Download your video in all selected formats instantly. Ready to post to multiple platforms.
