A great LinkedIn post is half visual, half text - and visuals do the heavy lifting of stopping the scroll. Getting your images right can be the difference between a post that gets ignored and one that sparks conversation and builds your brand. This guide will walk you through exactly how to create compelling, professional images for your LinkedIn posts, covering everything from design principles to practical tools and actionable strategies.
In a sea of text-heavy updates, resumes, and articles, a striking image acts as a visual anchor. It’s not just about making your feed prettier, it’s about strategic communication. Posts with images receive significantly more engagement - meaning more comments, shares, and visibility. A well-designed visual clarifies your message instantly, makes complex information digestible, and reinforces your brand identity with every post.
Think of it this way: the text in your post tells the story, but the image gets people to notice the story in the first place.
Creating beautiful images is pointless if they get cropped awkwardly by LinkedIn’s feed. Using the right dimensions is the first and most important step. Here are the latest specs to keep handy.
A quick tip: Always prioritize the mobile view. The vast majority of LinkedIn users are browsing on their phones. Keep text large enough to be legible on a small screen and avoid cluttering the edges of your design where they might be cut off.
Not all images are created equal. A generic stock photo won’t perform nearly as well as an image that adds unique value or shows a human side to your brand. Here are some of the most effective types of images to use on LinkedIn.
LinkedIn is a platform for professionals who appreciate data-driven insights. Turn a boring statistic or a key finding from a report into a simple, branded chart, graph, or mini-infographic. This positions you as an expert and provides genuine value to your audience. The key is to keep it simple: focus on one main data point per visual to avoid overwhelming your viewer.
Got a powerful takeaway from a podcast, a memorable line from a team meeting, or an inspiring quote? Put it on a branded background. Quote cards are perfect for creating scannable, shareable content. Using your brand fonts and colors makes them instantly recognizable as yours as they get shared across the platform.
Example: Post an image with the text, "Your calendar is not your to-do list. It's a plan for getting your most important work done." Then, use the caption to elaborate on this productivity tip.
People connect with people, not just logos. Behind-the-scenes content humanizes your brand. Share photos of your team working on a new project, setting up for an event, or even just having a coffee break. These glimpses into your company culture build trust and make your brand more relatable and authentic.
Showcasing your customers or community members is a powerful form of social proof. Share a photo of a customer using your product, highlight a testimonial (with their permission, of course!), or celebrate a community member's achievement. This makes your audience feel seen and valued, strengthening your community bonds.
Example: If you run a SaaS company, share a screenshot of a user's glowing comment on a feedback board (with name blurred or with permission) and thank them for their input in your post copy.
Hosting a webinar, attending a conference, or celebrating a company milestone? Visuals are non-negotiable. Create a clean, branded graphic to announce an upcoming event. During and after the event, share photos of your team, the speakers, or attendees to create a sense of community and an element of FOMO (fear of missing out) for the next one.
Sometimes the best way to start a conversation is simply to ask a question. Create a simple graphic with a thought-provoking question related to your industry. For example, a marketing agency might post an image that asks, "What's the one marketing metric you *actually* care about?" The strong visual stops the scroll, and the question invites immediate engagement in the comments.
Ready to get started? Here’s a simple process you can follow for every post.
Before you even open a design tool, ask yourself: What is the single most important message of this post? Are you trying to educate, inspire, announce something, or drive traffic to a blog post? Your visual should directly support that one goal. A cluttered image with competing messages will confuse your audience.
You don't need to be a professional graphic designer to create stunning visuals. There are plenty of user-friendly tools available:
Consistency is what transforms random posts into a recognizable brand. Stick to your branding rules on every single graphic.
The best digital designs are often the simplest. Embrace white space (or negative space) to give your elements room to breathe. Don’t cram too much text or too many design elements onto one image. Remember the one-message-per-post rule. Is the key takeaway immediately obvious within 3 seconds? If not, simplify.
Alternative Text (Alt text) is a description of your image that serves two purposes:
Don’t skip this step! Write a clear, descriptive sentence that explains what's happening in the image. For example, instead of "graphic," write "A pie chart showing that 75% of marketers prioritize content consistency in their social media strategy."
Creating standout images for LinkedIn isn't about having enterprise-level design skills, it's about clarity, consistency, and a little bit of creativity. By using the right dimensions, choosing proven formats, and staying true to your brand, you can produce visuals that stop the scroll and turn passive viewers into an engaged community.
