How to Post to All Social Media at Once (Free and Paid Ways)

Pick the one that matches how many platforms and accounts you post to.

If your brand only lives on Facebook and Instagram, you don’t need another tool. Meta Business Suite posts to both from one screen, and it’s free.

1. 1

   Open Meta Business Suite

   Go to business.facebook.com, or open the Meta Business Suite app, and sign in.

2. 2

   Create a post

   Click Create post. Under “Post to”, select your Facebook Page and your Instagram account.

3. 3

   Write once, then adjust

   Add your caption and photos or video. You can change the text for Instagram or Facebook on its own if you want.

4. 4

   Preview and publish

   Check the preview for each app, then publish now or schedule it for later.

The Instagram app can also do it: on the last screen before you share a post, turn on Also share on to send it to your Facebook Page, and to Threads where your account offers it.

Most schedulers have a free plan or a free trial. Free plans work if you post for one brand on two or three platforms. Here’s what the main ones give you:

Each platform also has its own free scheduler: YouTube Studio, TikTok on the web, LinkedIn’s post scheduler and Meta Business Suite. They work, but only for their own platform, so you still open each one.

The free combo, and where it breaks

A common free setup is Buffer for 3 channels plus each platform’s own scheduler for the rest (see our comparison of free social media schedulers). That’s fine for one brand. It breaks when you add clients: 3 clients on 5 platforms is 15 channels, far past any free plan, and you’re back to switching between apps.

A cross-posting tool connects all your accounts in one place, so one post goes to every platform. Here’s how it works in PostMax, which posts to X, LinkedIn, Facebook Pages, Instagram, YouTube, TikTok, Threads and Bluesky.

1. 1

   Make a profile for each brand or client

   Each profile holds only that client’s accounts, so you pick the client first and their posts go to their pages.

2. 2

   Connect the accounts

   Link each platform once. For most platforms you sign in on the platform’s own page, so PostMax never sees the password.

3. 3

   Write the post once

   Add your words, photos or video, and pick the platforms it should go to.

4. 4

   Change what each platform needs

   Write a shorter caption for X or Bluesky, add a YouTube title and description, or add a cover photo for YouTube and Instagram Reels.

5. 5

   Post now or pick the exact minute

   Scheduled posts go out on time even when your laptop is off. You can edit a scheduled post until a minute before it goes out.

6. 6

   Watch each platform go live

   Each platform shows when it’s done, with a link to the live post you can send to your client. If one platform has a problem, the others still post.

To be clear about what PostMax doesn’t do: it has no analytics, approval steps or team seats. It’s built for one person posting for many brands. If your agency needs approval chains, a team tool like Hootsuite or Sprout Social fits better.

One post can go everywhere, but each platform has its own rules. The most common problem is a caption that’s too long, so start there. Paste yours below.

Caption limits

Photo and video rules

Some platforms won’t take a post without the right media. These are the limits for posts sent through scheduling tools:

Post the same idea everywhere. Change the words when a platform needs it. People follow you on several apps for different reasons, and a little tailoring goes a long way:

• X, Threads and Bluesky: short and conversational. Cut the caption to its main point.
• LinkedIn: a bit longer and more useful. Put the key line first, since the rest hides behind “more”.
• Instagram and TikTok: the video or photo does the work. Keep the caption short, add a few relevant hashtags, and point to the link in your bio.
• YouTube: write a clear title people would search for, and a description with the key words.

Always upload the original video file. Instagram has said it shows Reels with another app’s watermark, like TikTok’s, to fewer people. A tool that posts the same file to every platform avoids this.

• Is the caption short enough for X (280) and Bluesky (300)?
• Do Instagram, TikTok and YouTube have a photo or video?
• Does YouTube have a title, and do YouTube and Reels have a cover?
• Is the video vertical 9:16 and short enough for every platform?
• Are links only where they’re clickable (not in Instagram or TikTok captions)?
• Is this the right client’s profile?
• Is the time right for your audience’s time zone?

Cross-posting gets harder with every client. You have more accounts, more logins, and more chances to post on the wrong page. Two things matter most:

• Separate profiles. Each client should have their own space with only their accounts in it, so you choose the client first and can’t mix them up.
• A price that doesn’t grow with clients. Many tools charge per channel or per user. At Buffer’s $5 per channel (billed yearly), 4 clients on 5 platforms is 20 channels, or about $100 a month before its volume discount. PostMax is $9.99 a month for unlimited clients and accounts.
