Video Resizer

Video resizer & aspect ratio converter

One video, every aspect ratio — 9:16, 16:9, 1:1.

VidMints resizes and reframes your video for any platform. Turn a landscape clip into vertical 9:16 for TikTok, Reels and Shorts, square 1:1 for feed posts, or keep 16:9 for YouTube — and keep the subject in frame instead of chopping it off. Resize on the editor timeline and finish captions, audio and export in the same place.

What is Video resizer & aspect ratio converter?

Every video platform expects a particular shape. YouTube is built around wide 16:9, TikTok, Reels and Shorts want tall 9:16, and many feed posts look best as a 1:1 square. When a clip is the wrong shape for where it is going, the platform either wraps it in black bars or crops it automatically — often cutting off the very thing you filmed. A video resizer fixes that by changing the frame to the ratio you need.

The important part is not just cropping to a size but reframing while you do it. VidMints lets you choose the target ratio and then position the shot inside the new frame, so a person or product that was near the edge of a landscape recording stays centred once it becomes vertical. That is the difference between a converted clip that looks deliberate and one that looks like it was squeezed to fit.

Because resizing happens on the editor timeline rather than in an isolated one-off tool, the rest of your edit comes with it. You can trim, add captions and adjust audio in the same project, and export more than once at different ratios — so a single recording can become a wide YouTube version and a vertical short without redoing the work.

Why use Video resizer & aspect ratio converter?

Filming the same thing separately for every platform is wasteful, and letting each app auto-crop your upload gives away control of what stays in frame. A resizer lets you record once and adapt deliberately, keeping the subject visible whether the destination is tall, wide or square. It is especially useful for repurposing: a landscape interview or webinar becomes vertical clips for short-form, and a horizontal ad becomes a square for the feed, all from one file.

Who it's for & example uses

Repurposing long-form to short-form

Pull a vertical clip out of a landscape podcast, webinar or interview so it fits TikTok, Reels and Shorts without letterbox bars.

Running one ad across placements

Export a single promo as 16:9, 1:1 and 9:16 so the same creative fits in-stream, feed and story slots.

Creators posting everywhere

Take one recording and ship a wide version for YouTube and a tall version for shorts from the same edit.

Tips for the best results

Pick the ratio for your main platform before you add captions or graphics, so text is placed to fit that frame rather than repositioned later.
When converting landscape to vertical, reframe on the subject — usually a face or product — so the centre of interest is not left in a corner.
In vertical 9:16, leave a little headroom at the top and bottom for the platform's own buttons and captions that overlay the video.
Export your widest version first, then create the tighter crops, since it is easier to reframe inward than to recover edges you have already cut.
Keep on-screen text away from the extreme edges so it survives every crop and stays inside safe areas across platforms.

Frequently asked questions

Can I turn a landscape video into vertical?

Yes. Switch a 16:9 clip to 9:16 and reframe it so your subject stays centered, which is exactly what TikTok, Reels and Shorts need.

Which aspect ratios are supported?

The common short- and long-form ratios: 9:16 (vertical), 16:9 (landscape) and 1:1 (square). Choose the ratio before you export.

Will resizing crop out my subject?

You reframe the shot when you resize, so you can keep the important part of the frame in view rather than letting the edges get cut off automatically.

Can I export the same video in more than one ratio?

Yes. Export your edit at one ratio, then switch and export again — one recording can cover every platform.
