Screenshot Mockup Generator

Raw screenshots have a place — bug reports, internal docs, customer support — but they are almost always the wrong format for anything public-facing. A raw screenshot has no border, no shadow, no context, so the eye reads it as a UI fragment instead of a product. That works against you on Twitter and LinkedIn, where you are competing for attention with images that have been deliberately composed. A mockup adds three signals at once: device context (this is a real product running on a real device), production polish (someone cared enough to frame this), and brand identity (the background and frame choices tell the viewer what kind of product this is before they read a word).

There is one specific case where the raw screenshot wins: technical proof. If you are showing a terminal output, a config diff, or an “it actually works” moment to a developer audience, a device frame can feel performative and undermine the credibility you are trying to build. For everything else — landing pages, change-logs, launch tweets, sales decks, App Store listings — a mockup converts measurably better. If your launch deck still has flat un-framed screenshots in it, swap them through our mockup generator in fifteen minutes before the next pitch.

Each platform crops images differently and rewards different composition. Twitter previews land in feeds at roughly 16:9, so anything taller gets center-cropped and the top and bottom of your mockup disappear. Compose your mockup so the device frame and any text overlay sit inside the middle 70% of the canvas. LinkedIn is the opposite — square (1:1) and 4:5 portrait images take up significantly more vertical space in the feed, which means they earn more dwell time. Export the same mockup at 1:1 for LinkedIn and 16:9 for Twitter rather than reusing one ratio everywhere.

Product Hunt is a special case. The gallery on a Product Hunt page renders thumbnails small, but the first image becomes the social card the platform pushes to email and Twitter, so it has to read at thumbnail size. Use a tight crop with big text and a single device, not a wide multi-device hero shot — the multi-device shot looks great on the page but illegible in the email. For animated mockups (scroll-recordings, click-throughs), keep the loop under six seconds and the file under 8MB or Twitter will silently transcode it into a low-quality MP4. The Product Hunt gallery generator ships templates pre-sized to each gallery slot for exactly this reason.
