What Postblast Does

One tool. Four platforms.
Zero copy-paste.

Built for creators who want to spend time making content, not managing accounts.

One-click publishing

Upload your video once and Postblast sends it to TikTok, Instagram, YouTube, and X in a single blast. No duplicate tabs, no manual reposting.

AI trend intelligence

Postblast reads what is trending right now across platforms and tells you exactly how to align your next upload with the moment — before the wave passes.

Creator-first design

Built for solo creators, not marketing teams. Every screen is designed around your workflow — not a 20-person agency managing client accounts.

Platform management

Connect and manage all four platforms from a single hub. See which accounts are live, which need attention, and control everything without switching apps.

How It Works

From upload to
everywhere in seconds

Three steps stand between your raw file and a live post on every platform you care about.

Upload your video

Drag and drop a file into the Postblast upload hub. MP4, MOV, or any major video format. One file is all it takes — Postblast handles the format conversion each platform needs.

Choose your platforms

Toggle TikTok, Instagram, YouTube, and X on or off with a tap. Post to all four at once or pick a subset for a specific drop. Your connected accounts remember your settings.

Hit Blast It

One button sends your video live across every selected platform simultaneously. No queue, no waiting room. Before you close the tab, you are live everywhere.

Blast It

Upload once.
Reach everywhere.

The same video. TikTok, Instagram, YouTube, and X. All at once, every time — without opening four tabs or copy-pasting four captions.

Product Features

Three screens. Every tool
you actually need.

Upload & Publish

Your content goes live on all four platforms at once

The Postblast upload hub accepts your raw video file and pushes it to TikTok, Instagram, YouTube, and X simultaneously. Pick which platforms you want, write your caption once, and blast. That is the whole process.

  • Drag-and-drop or browse to upload
  • Per-platform toggle — post to all or pick a subset
