Upload a video once, write your title and caption, choose Facebook, TikTok, YouTube and Instagram — all of them or just the ones you want — and get a ready-to-post pack for each platform you picked.
MP4, MOV, WebM and other common video files.
Written once — shaped automatically for each platform.
Post everywhere, or only where you want this one.
A quick checklist that applies to every platform.
Use a video you made or have the rights to post — platforms remove re-uploaded content and can restrict accounts for it.
Vertical videos (9:16) fill the screen on TikTok, Reels and Shorts. Longer, wider videos suit YouTube and Facebook feeds.
Post from your own signed-in account on each platform — that's what keeps your pages and channels under your control.
Exactly what will go out on each platform you picked. Copy the text or download the whole pack, then post it in each app.
Add your video, title and caption here, and choose your platforms. This page checks the shape and length of your video and flags anything a platform would reject or crop.
Download the post pack or copy the text for a platform. The pack holds your title, caption and a short per-platform checklist so nothing gets missed.
Open Facebook, TikTok, YouTube or Instagram, upload the same video file, paste the text from your pack and hit post. Four platforms, a couple of minutes.
This is a public page anyone can open, with no sign-up. Posting directly into an account requires signing in to that account — and a public page holding everyone's sign-ins wouldn't be safe for anyone. So this page does everything up to the final tap: it prepares the exact text and checklist for each platform, and you post from your own signed-in apps, where your accounts stay yours.
No. The video is read only by your own browser so you can preview it and check its size, length and shape. It is never sent to a server, and it disappears when you close the page.
Vertical 9:16 (for example 1080 × 1920) is the best all-rounder for TikTok, Instagram Reels, Facebook Reels and YouTube Shorts. A vertical video under 3 minutes can go out as a Short on YouTube; longer or horizontal videos still work everywhere as regular video posts.
TikTok and Instagram cap captions at 2,200 characters. Facebook allows much longer posts, and YouTube uses your title (up to 100 characters) plus a description. The counters above warn you before you pass a limit.
