How to Schedule LinkedIn Posts: Free & Tool Options (2026)

Why scheduling LinkedIn posts is a different problem

LinkedIn is not a forgiving publishing target. It has a 3,000-character limit on both profiles and Pages, it rejects media on thread parts, and it has no native concept of a carousel. Publishers learn this the hard way: a post that works fine on X gets truncated, a document upload gets rejected, and a multi-part thread silently loses its media.

Three structural quirks cause most of the friction, and each one changes what a good scheduling tool needs to do.

1. Carousels are PDFs, not a native format

A LinkedIn "carousel" is a document share. LinkedIn renders a PDF as a swipeable document, and there is no API that accepts a set of slides. Every scheduler therefore has to solve the same problem: combine your images into a PDF, then upload that PDF as a document. Most tools push this back onto you as a manual step. Postiz does the conversion automatically — attach two or more images and it builds the PDF and uploads it as a document share.

2. A profile and a Page are different channels

Postiz treats them as two separate providers, linkedin and linkedin-page, and each connected account consumes one channel from your plan. This matters for more than billing. Analytics are available for LinkedIn Pages but personal profiles expose far less through the official API, so profile-level performance data stays thin. If you build a reporting habit around Pages, do not expect the same numbers from a personal profile.

3. Comments are text-only

If you write a multi-part post, the extra parts become comments, and LinkedIn rejects media attached to them. Any tool promising to schedule a LinkedIn thread with images in the replies is going to fail at publish time rather than at save time.

What LinkedIn's own scheduler does (and does not do)

LinkedIn ships a native scheduler, and it is genuinely good for what it covers. You can schedule a post from roughly one hour ahead to three months in advance, on both personal profiles and company Pages, from the clock icon in the composer. It supports text, images, video, and document uploads, it is free, and it needs no third-party account. If you publish three posts a week on one LinkedIn account and never touch another network, the native scheduler is the correct answer.

Here is the honest limit of that approach:

The trade is simple. Native scheduling is free and instant but single-network and manual. A tool like Postiz costs money or a server, and buys you one calendar, one workflow, and automatic formatting per network.

How to schedule LinkedIn posts the manual way

Before paying for anything, it is worth knowing exactly what the manual workflow looks like, because that is the baseline you are trying to beat.

1. Write the post. Keep it under 3,000 characters. Write a longer version for LinkedIn and a shorter one for X, rather than truncating one master copy.
2. Build the carousel if you need one. Export your slides as images, combine them into a single PDF, and confirm the page size reads well on a phone.
3. Open the LinkedIn composer. Paste the text, upload the PDF as a document.
4. Check the timezone. LinkedIn schedules in UTC. If you are in a non-UTC region, the slot you pick is not the slot you get.
5. Set the time and confirm. You get a range of about one hour to three months.
6. Repeat for every other network. This is the step that quietly eats the time you were trying to save.

Steps one through five are maybe three minutes per post. Step six is where manual scheduling falls apart, and it is the reason people look for a tool at all.

How to schedule LinkedIn posts with Postiz

Postiz is an open-source social media scheduling tool, released under AGPL-3.0, that you can use as a hosted service or run yourself. It supports 34 platforms, and LinkedIn is one of them. Here is the workflow.

Step 1: Connect your LinkedIn account

On Postiz Cloud, click Add Channel and choose LinkedIn. You are redirected to LinkedIn, approve the request, and land back in Postiz with the channel connected. For a Page, LinkedIn asks which company you want to post to as a follow-up "continue integration" step — the channel is not usable until you finish it. The same flow works for a personal profile.

Step 2: Write the post and pick the channels

The composer lets you write once and target every channel, then preview each one separately. This is the feature that matters most for LinkedIn specifically: the LinkedIn preview gets the long-form version with the document attached, while the X preview gets a trimmed variant. You are not publishing identical text everywhere.

Step 3: Attach the carousel images

Add two or more images. Postiz combines them into a PDF and uploads it as a document share, which is how LinkedIn implements carousels. You do not upload a PDF yourself, and you do not need a separate design tool to produce one.

Step 4: Schedule and approve

Pick a date and time, or publish immediately. Posts sit on a shared calendar that you can drag, reschedule, duplicate, or delete. On higher plans you can send a post to a client for approval, collect their comments, and publish once it clears.

Scheduling LinkedIn posts for a Page and a profile together

Because Postiz treats these as separate providers, you connect both, choose both in the composer, and publish to each with its own preview. It also means each one consumes a channel slot. On Postiz Cloud the tiers are Standard at $29 per month for 5 channels, Team at $39 for 10, Pro at $49 for 30, and Ultimate at $99 for 100, with unlimited posts per month on every paid plan. Team seats are not counted, so adding people to your organisation does not raise the price.

Self-hosting removes the channel cap entirely. The AGPL edition lets you run unlimited channels, unlimited posts per month, and unlimited team members on your own infrastructure. The trade is that you own the server, and you manage the credentials. See how a self-hosted Postiz stack is put together in our Docker install guide.

The settings object must carry a __type field naming the platform — linkedin for a personal profile, linkedin-page for a company Page. The public API, the CLI, and the hosted MCP server are included on every Postiz Cloud plan, so an AI agent or an n8n workflow can queue a LinkedIn post without a human opening a browser. Full reference is in the Postiz public API docs.

Self-hosting: what the LinkedIn setup actually requires

This is where most self-hosted setups quietly break, so it is worth being precise. Connecting LinkedIn on your own instance requires your own LinkedIn developer app, and it needs three products enabled: Share on LinkedIn, the Advertising API, and Sign In with LinkedIn using OpenID Connect.

Under the Auth tab, the OAuth 2.0 scopes list must show every scope Postiz requests:

• openid and profile — from OpenID Connect
• w_member_social — from Share on LinkedIn, for personal profiles
• r_basicprofile
• rw_organization_admin, w_organization_social, r_organization_social — from the Advertising API, for Pages

Two warnings from the official provider documentation are worth repeating. First, request the Advertising API permissions and complete the request form, or you will not be able to refresh tokens and your channel will break when the access token expires. Second, the organization scopes are required for the regular LinkedIn provider too, not just the Page one — both providers share the same app and the same scope set.

If a scope is missing, LinkedIn does not fail the login. It issues a token without that scope, and Postiz rejects the connection with a NotEnoughScopes error. The Auth tab list is the first place to check.

The full self-host walkthrough, including the Docker and Helm paths, is in the Postiz LinkedIn provider documentation. The open-source repository is at gitroomhq/postiz-app if you would rather read the source than the docs.

The bottom line

Learning how to schedule LinkedIn posts is easy; learning how to schedule them well is where the platforms differ. The native scheduler gives you a clock and a calendar, and for a single account posting a few times a week that is genuinely the whole job. The moment you need carousels built for you, a shared content calendar, a Page and a profile running side by side, or the same idea published to a dozen networks without rewriting it twelve times, a dedicated scheduler is what you are actually buying.

Postiz is a credible choice for that job because it is open source, handles the awkward LinkedIn specifics correctly, and caps pricing on channels rather than on output. Start with the trial, connect one profile and one Page, and see how much of your weekly work it removes. If you want the same thing without a subscription, the self-hosted edition is free and uncapped, and the only real cost is your own server and one LinkedIn app approval.
