Social media mockup generator

Drops your image into a generic post or ad frame with a brand name, headline and body copy, cut at the 125-character fold most platforms use, so you can judge the assembled unit rather than the separate files it was built from.
How to use the social media mockup generator
Every platform folds the caption somewhere between 100 and 150 characters, so treating 125 as the working number gets you close everywhere. The value of a generic mockup is not accuracy to one platform but the discipline of looking at image and copy together at small size, which is where the two most common mistakes show up: an image that needs to be big to work, and an opening line that spends the fold on a greeting. Both are obvious in a frame and invisible in a folder. Paid creative fails in the same place and slightly harder, because there are more parts to collide. An image that works alone competes with a headline that also works alone; the call to action lands on the busiest part of the picture; the brand name ends up the third most prominent thing when it should be the second. None of that is visible in a folder of assets, and the single most common problem it exposes is excess — two messages fighting for the same second of attention where one clear one would land.
What people use it for
- Judging a post image and its opening line together at phone size
- Checking that the hook lands before the 125-character fold
- Assembling an ad unit from image, headline and body to see where they collide
- Checking that a call to action does not land on the busiest part of the image
- Catching creative that carries two competing messages
Questions
None exactly. It uses a 125-character fold, which is close to Facebook, Instagram and LinkedIn.
To judge image and copy together at small size. That is where most problems show, and they are platform-independent.
Seeing the assembled unit. Ads usually fail where the image and the copy meet, which is invisible when you review them separately.
No. It is rendered in your browser.
Not as a file: take a screenshot. The creative itself is your own image.
No, and it cannot be. Platforms cut by rendered pixel width, so a title in capitals or wide letters cuts earlier than a character count suggests. Treat the limit as a guide and leave a few characters of margin.
No, it is a generic square unit. Use the platform size specs for exact placements.
A square works here. 1080 × 1080 is the safe upload size across feed placements.
Scale. An image reviewed full-screen reads differently at phone size beside other posts, and detail that seemed like the subject disappears.
That is roughly where a Facebook or LinkedIn ad headline truncates. It is the shortest of the common ones, so a headline that fits it fits everywhere.
You can — Meta dropped the hard 20 percent text rule — but text-heavy images still tend to underdeliver, and at phone size a strapline is unreadable anyway.
Drop in the frame you would use as the thumbnail. That still is what gets judged in a scroll, whether or not the video autoplays.
