Resizo Open Video Studio

Resize video for social media

Take one video and produce the versions each platform actually wants. The sizes are here as presets so you do not have to look them up, and you can export a square, a portrait and a landscape cut from the same source in a few minutes.

Questions

What video sizes do social platforms use?

Almost all vertical video is 1080 × 1920 — Reels, TikTok, Shorts and Stories all share it. Square is 1080 × 1080, Instagram’s taller feed post is 1080 × 1350, and landscape is 1920 × 1080 for YouTube and LinkedIn or 1280 × 720 for Facebook and X.

Can I use one video everywhere?

A 9:16 vertical export is accepted by every platform, but it will be letterboxed on YouTube and look cramped on LinkedIn. Exporting a vertical and a landscape version covers almost everything properly.

How do I make a landscape video work as a Reel?

Set the canvas to 1080 × 1920 and choose "Blurred background". The whole picture stays visible in the middle and the space above and below is filled with a blurred copy of it.

Will the platforms compress my video again?

Yes, all of them do. Export at the highest quality you reasonably can so their compression starts from a good source.

Is there a watermark?

No, on any export.
