The trick to getting a landscape video into portrait format without losing the edges is letterboxing with a fill. The landscape clip stays centered at its original size, and the new vertical canvas is filled with a blurred copy of the same video. Nothing is cropped. It is the same technique TV networks use when they show old 4:3 content on 16:9 screens — just flipped vertical.
Why cropping ruins most landscape footage
A 16:9 video fills 1920x1080. Crop it to 9:16 (1080x1920) and you throw away 67% of the horizontal pixels. If anything important is near the left or right edge — a second person, a product on a table, text over the scene — it is gone.
Auto-crop tools try to fix this by tracking subjects, but they fail on wide shots, group scenes, whiteboards, B-roll, and anything with more than one focal point. Reframing with a background fill sidesteps the problem entirely.
How background fill works
The tool scales the new canvas to your target aspect ratio (9:16, 4:5, 1:1, or 16:9). Your original video lands in the center at its native resolution. The remaining space — above and below for 9:16, left and right for 16:9 — gets filled with a blurred, zoomed-up copy of the video, a gradient, or a solid color.
Blurred fill is the most popular because it ambient-matches the scene's lighting. If your video is outdoors at golden hour, the background glows warm. If it is a dark interior, the background is dark. No color mismatch, no distracting pattern.

- Open the reframe tool.
- Drop your landscape MP4 or MOV into the upload area.
- Pick your target ratio. 9:16 for TikTok/Reels/Shorts, 4:5 for Instagram feed, 1:1 for Twitter, 16:9 for YouTube.
- Choose background style. Blurred works for 95% of cases.
- Render. 10-30 seconds for most clips.
- Download the MP4. Audio is preserved.
When cropping is actually better
Reframing is not always the right call. If you have a single centered subject with nothing important near the edges, cropping wins because the subject appears larger on the viewer's screen. The blurred-sides style can look lazy if the composition is already portrait-friendly.
Rule of thumb: crop for talking-head with clean backgrounds, reframe for anything busier. For cropping, use the crop video tool instead.
Aspect ratio cheat sheet for converting landscape
| Target | Use case | Final resolution |
|---|---|---|
| 9:16 | TikTok, Reels, Shorts, Stories | 1080x1920 |
| 4:5 | Instagram feed (tall) | 1080x1350 |
| 1:1 | Twitter/X, LinkedIn feed | 1080x1080 |
| 16:9 | YouTube, Facebook | 1920x1080 |
If you cannot decide between 4:5 and 9:16 for Instagram, 4:5 has the edge — it takes up more screen real estate in the feed than 1:1 and does not trigger the "tap to enter Reel" reformatting that 9:16 does.

Yes. Everything runs in your browser. You do not install anything, create an account, or upload the file to a server. The processing happens on your device.
How do I handle 4K source footage?
Drop the 4K clip in and the tool scales it to the target resolution. 4K to 1080x1920 is the most common path. Processing takes slightly longer but quality is preserved.
Can I customize the background color?
Yes. Pick the solid color option and choose any hex code. Brand colors, black bars, or a transparent-looking gray all work.
What file formats are supported?
MP4 (H.264, H.265), MOV, WebM, and most common formats. Output is MP4 H.264 for maximum compatibility with social platforms.
