App Store Screenshot Generator: Make Professional App Marketing Images Easily
You've spent six months building your app, and right before launch you notice a painful problem: your product images are ugly.
Not "I think they could look better" ugly. The kind where people open your App Store page, see the screenshots and want to swipe away.
Don't ask how I know. I've seen too many developers crash at this step.
The data doesn't lie
63% of App Store users decide whether to download based on the app's screenshots. And the average time spent on your screenshots is under 3 seconds.
In other words, if you don't grab users within 3 seconds, you don't even get a chance to explain.
Here's the problem:
- You're not a designer, and Sketch/Figma gives you a headache
- Outsourcing costs from 500 yuan per image, plus rounds of revisions
- Throwing something together in PowerPoint gives results... you don't even want to look at yourself
Worst of all, iPhone and iPad sizes are different. Portrait, landscape, Plus, Pro Max... adapting to all of them eats half a day.
The way out: a tool that makes screenshot generation simple
I've tried quite a few screenshot generators. The one I kept is an online tool: the App Store Screenshot Generator
This isn't an ad. I genuinely think it solves a real problem: no software to install, it works in the browser, and you get images in 5 minutes.
Here's what it can do:
| Feature | Details |
|---|---|
| Devices | iPhone 6.5-inch (portrait/landscape), iPad Pro 12.9-inch (portrait/landscape) |
| Backgrounds | 13 preset colors + custom colors + gradients |
| Text | Headline + subheadline, with text style adapting to the background automatically |
| Effects | Automatic rounded corners, borders and shadows, no manual Photoshop work |
| Export | JPEG at 85% quality, with smart file naming |
Supported device sizes
iPhone 6.5-inch (portrait)
- Resolution: 1242 × 2688 px
- For: iPhone 14 Pro Max, 13 Pro Max, 12 Pro Max and other large-screen models
iPhone 6.5-inch (landscape)
- Resolution: 2688 × 1242 px
- For: landscape use on the same large-screen models
iPad Pro 12.9-inch (portrait)
- Resolution: 2048 × 2732 px
- For: the entire iPad Pro 12.9 line
iPad Pro 12.9-inch (landscape)
- Resolution: 2732 × 2048 px
- For: landscape use on the same line
Color schemes
The tool comes with a curated set of colors, not a random grab bag:
Basic colors
- White, light gray, dark gray, blue, purple, pink, green
Gradients
- Blue gradient, purple gradient
Business styles
- Navy, slate gray, burgundy, forest green
The logic is clear: either clean and simple, or textured without being flashy. That suits app screenshots well.
5-minute walkthrough
- Open the tool and pick your target device and orientation (portrait/landscape)
- Pick a background from the presets, or set a custom color that fits your brand
- Add text: a headline and subheadline. The tool adjusts the text color automatically to keep it readable
- Upload your screenshot, and rounded corners, borders and shadows are added automatically
- Preview and export: once it looks right, download with one click
The whole process needs no design background, and you don't have to worry about sizes: whichever device you pick is the size you get.
Honest take
This tool can't do everything. If you need very complex marketing images with lots of explanatory text, it won't cut it.
But if you just need clean, usable screenshots that meet App Store requirements, it's more than enough.
Isn't it nicer to spend the time you save writing your product description or handling user feedback?
