Question 1

What is a LinkedIn mockup and why do I need one?

Accepted Answer

A LinkedIn mockup places your creative inside a realistic rendering of the feed, with the avatar, name, headline, post chrome, and action row around it, so you see the asset the way an actual member will see it rather than as a file on a white background. The reason this matters is that context changes everything. A design reviewed at full size in a design tool looks confident and legible. The same design in the feed is smaller, surrounded by competing posts, cropped by the container, and glanced at for under two seconds on a phone. Type that felt generous becomes unreadable, a logo that felt prominent disappears, and a subtle gradient turns into a gray smear. Reviewing in context catches all of that before you spend media budget on it. It also changes the conversation with stakeholders, because everyone is looking at the same realistic artifact instead of imagining one.

Question 2

How do I show stakeholders what a post will look like before it goes live?

Accepted Answer

Show them a mockup, not a file. Attaching a PNG to an email invites a review of the PNG. Showing the same asset sitting in a feed invites a review of the post, which is the thing you are actually shipping. In practice this collapses review cycles. The two most expensive kinds of feedback in a marketing team are the late kind and the vague kind, and both are usually artifacts of poor presentation. "Can the logo be bigger" arriving after launch is a rework cycle. The same note arriving because a stakeholder could see the logo vanish in a feed-size render is a five-minute fix. For approvals with legal, compliance, or an executive sponsor, in-context review is close to mandatory. It is the only way to demonstrate what a real viewer sees, which is the standard those reviewers are actually applying even when they cannot articulate it.

Question 3

What does the LinkedIn feed do to my image?

Accepted Answer

Three things, all of which degrade an unprepared design: - It shrinks it. A 1200 px square renders a few centimeters wide on a phone. Everything you thought was legible is now roughly a third of the size you designed it at. - It crops it. Different surfaces (mobile feed, desktop feed, notification previews, reshares) frame images differently, and anything within about 10% of an edge is at risk. - It surrounds it. Your creative appears between a colleague's promotion announcement and an industry news post, competing for attention rather than sitting in the silence of a design canvas. The design consequences follow directly: one message per asset, headline type large enough to read at a glance, critical content pulled toward the center, and enough contrast to survive both a small render and a dim screen.

Question 4

How large does my text need to be to stay readable in the feed?

Accepted Answer

Size type as a proportion of the frame, not in absolute points, because the render size varies. As a working standard for a 1080 or 1200 px square: headline type should occupy at least 6% to 8% of the frame height, subheads around 4%, and nothing critical should fall below about 3%. Then apply the arm's-length test. Open the mockup on your phone, hold it where you would normally hold it, and glance for two seconds. If you have to squint or pull the phone closer, the design fails, no matter how good it looks on a 27-inch monitor. Contrast is the other half. Aim for a ratio of at least 4.5:1 between text and its background, and put a solid shape or scrim behind any type sitting over a photograph. Thin, elegant, low-contrast typography is the most common failure mode in B2B creative, because it reviews beautifully at full size and disappears entirely at feed size.

Question 5

What makes LinkedIn creative stop the scroll?

Accepted Answer

Feed behavior is fast and unforgiving, so the rules are blunt: - One idea per asset. If your image needs two sentences to explain itself, it will be scrolled past. - Lead with the tension, not the solution. The problem your buyer recognizes stops them; your product name does not. - Use contrast deliberately. The LinkedIn feed is predominantly white and blue, so a dark or saturated brand asset stands out structurally, before anyone reads a word. - Faces and specific numbers earn attention more reliably than abstract illustration and generic stock. - Make it unmistakably yours. Consistent color, type, and layout mean the third impression benefits from the first two. Anonymous creative restarts from zero every time. - Do not put the call to action in the image alone. The image earns the stop; the copy and the button do the converting.

Question 6

Should I review on mobile or desktop?

Accepted Answer

Judge on mobile, check on desktop. The majority of LinkedIn sessions happen on a phone, so mobile is where your creative actually lives and where the constraints are tightest. If it works there, it will almost always work on desktop. Desktop is still worth a look for two specific things: wide assets that rely on horizontal detail, such as dashboards and diagrams, and any composition where the crop differs meaningfully between the two containers. If a design only works on desktop, that is not a design that works. A useful discipline is to review at actual device size rather than zoomed. Reviewing a mockup at 200% on a large monitor reintroduces exactly the false confidence the mockup exists to remove.

Question 7

How many creative variants should I review at once?

Accepted Answer

For a paid campaign, plan on four to six creatives per campaign, refreshed every two to four weeks. That is the amount of variety LinkedIn's auction needs to keep costs down, and it is the amount of rotation required to hold off frequency fatigue in a small, tightly targeted B2B audience. Review them side by side rather than sequentially, and review them in context. Sequential review flatters whichever asset you saw first; side-by-side comparison surfaces the one that genuinely reads fastest. Make the variants meaningfully different. Changing a background color is not a test. Test distinct angles, a customer-proof angle against a problem-agitation angle against a data-led angle, and distinct formats, since single image, document, and video behave differently in the feed. Then let cost per lead, not opinion, decide which survives.

Question 8

Does in-context review help with ad approval and brand compliance?

Accepted Answer

Considerably. Most rejections and most internal compliance escalations come down to legibility and clarity: a disclaimer nobody can read at render size, a claim that reads as unqualified once cropped, a logo lockup that breaks when scaled down. All of those are visible in a feed mockup and invisible in a full-size design file. It also gives regulated teams something concrete to sign off against. In financial services, healthcare, and similar sectors, the reviewer's real question is what a member will actually see, and a mockup answers it directly instead of asking them to imagine it. Practically, keep a mockup of the approved version alongside the approval record. When someone asks six months later what exactly was signed off, that artifact settles the question in seconds.

Question 9

Can I use these mockups in a deck, a proposal, or a client presentation?

Accepted Answer

Yes. The export is a high-resolution PNG, exactly as previewed, and it is yours to use in pitch decks, campaign plans, status reports, client proposals, and internal approval documents. There is no watermark and no attribution requirement. Agencies and consultants get the most value here: showing a client their asset in a realistic feed is far more persuasive than showing a flat file, and it moves the conversation from "do I like this picture" to "will this work in the feed", which is a much better conversation to be having. One honest caveat: the mockup reproduces the LinkedIn feed layout for review purposes and is not affiliated with or endorsed by LinkedIn. Do not present it as an official LinkedIn asset or use it in a way that implies a partnership.

Question 10

Is this mockup maker free, and does my image get uploaded?

Accepted Answer

It is completely free, with no login, no email, and no usage limit. And nothing is uploaded. The image is read, composited into the mockup, and exported entirely inside your browser using a canvas element, so the file never reaches a server and is never stored or seen by anyone else. That makes it safe for unannounced campaigns, unreleased product screenshots, and client work under NDA, which is exactly the material that most needs an in-context review before launch and is least suitable for an anonymous upload site.
