A generic screenshot generator only frames a screen. The screen inside the frame is what sells, so start there, for free, and the rest is mechanical.

**TL;DR.** A screenshot generator does three small jobs: it frames your screen in a device, adds a caption, and exports the required sizes. None of that beats a strong screen inside the frame. Build that screen free from a VP0 design, capture it in the iOS Simulator, frame and caption it in a free tool, and export the sizes App Store Connect needs. No subscription required.

Need App Store screenshots but do not want to pay for a generator? You do not have to. A screenshot generator only does three small jobs: it drops your screen into a device frame, adds a caption, and exports the sizes Apple wants. The hard part, the screen inside the frame, is where VP0 comes in, the free iOS design library for AI builders. Start from a polished screen and everything after it is free and mechanical.

## Who this is for

This is for vibe coders, indie hackers, and first-time publishers who have an app running in the simulator and now need store screenshots, without a subscription or a design background.

## What a screenshot generator actually does

A generator frames your screen so it reads as a real phone, adds a caption and background so the image sells a benefit instead of just showing pixels, and exports the exact dimensions Apple requires. That is the entire job. The paid tools dress it up with templates and gradients, but none of that is what makes a screenshot work. What makes it work is the screen inside the frame.

Apple lets you upload up to 10 screenshots per device, in PNG or JPEG with no transparency, and the first ones appear directly in search results. The [App Store screenshot specifications](https://developer.apple.com/help/app-store-connect/reference/screenshot-specifications) list the exact pixel sizes, and the [App Store Connect upload guide](https://developer.apple.com/help/app-store-connect/manage-app-information/upload-app-previews-and-screenshots) covers how to add them. Build at the largest required size and scale down for smaller slots without losing sharpness.

| Asset | Apple's rule | Practical move |
|---|---|---|
| iPhone size | 6.9 and 6.7 inch class | Build at the largest, scale down |
| iPad size | 13 inch, only if you support iPad | Skip if iPhone-only |
| Count | Up to 10 per device | Use 3 to 5 strong ones |
| Format | PNG or JPEG, no alpha | Export flat and high quality |
| First shots | Shown in search results | Put your 2 best first |

## Build it free with a VP0 design

A screenshot generator cannot rescue a half-built screen, and AI builders left to their own taste tend to output flat gray layouts. Give your AI builder a strong visual reference first. Pick a screen in VP0 that matches your category, copy its link, and prompt your builder:

> Rebuild this VP0 screen in SwiftUI and show it in its best looking populated state: [paste VP0 link]. Use realistic sample data, a friendly greeting, filled cards, and one clear primary action. No empty states, no Lorem Ipsum. Match the colors and spacing from the reference.

Now you have a screen worth framing. Capture it in the iOS Simulator with Cmd+S, drop it into a device mockup in [Figma](https://www.figma.com) or Keynote, add a one-line caption, and export. Paid generators run roughly $9 to $20 a month, and you skip all of it. For the exact pixel dimensions, pair this with [an App Store screenshot dimensions Figma template](/blogs/app-store-screenshot-dimensions-2026-figma-template/), and if you build with AI tools specifically, see [the screenshot workflow for vibe coders](/blogs/app-store-screenshot-generator-for-vibe-coders-free-ios-template-vibe-coding-gui/). When the listing copy comes next, [write an App Store description that ranks](/blogs/how-to-write-an-app-store-description-that-ranks/).

## Captions that convert

The image shows what your app looks like. The caption tells people why they should care, and it carries most of the persuasion. Lead with the outcome, not the feature: "Track every workout in one tap" beats "Workout logging screen." Keep each caption to one short line, front load the benefit so it survives cropping on smaller devices, and make the first two screenshots carry the strongest hooks. Treat the first screenshot as your headline and everything after it as supporting evidence.

## Common mistakes

The first mistake is paying for a generator when free tools export every size Apple accepts. The second is framing a half-finished, empty screen instead of a populated one. The third is feature captions instead of benefit captions. The fourth is filling all 10 slots with weak shots rather than leading with two strong ones. The fifth is hard-coding exact pixel sizes from a third party instead of checking [Apple's current specifications](https://developer.apple.com/help/app-store-connect/reference/screenshot-specifications), which change with new devices.

## Key takeaways

- You do not need a paid generator; free tools export every size App Store Connect requires.
- A screenshot is only as good as the screen inside the frame, so start with a polished UI.
- Build that screen free from a VP0 design, then capture, frame, and caption it.
- Lead with benefit captions and put your two strongest shots first.
- Confirm exact sizes against Apple's specifications, which change with new hardware.

## Frequently asked questions

Do I need a paid generator to make App Store screenshots? No. App Store Connect accepts any correctly sized PNG or JPEG, so you can frame and caption screenshots in free tools and upload them directly.

What is the best free App Store screenshot generator? The best free path is to start from a polished screen rather than a template. VP0 gives you that screen for free, then you capture it in the Simulator and frame it in any free tool.

What screenshot sizes does Apple require? Generally one large iPhone size in the 6.9-inch and 6.7-inch class and a 13-inch iPad size if you support iPad, up to 10 per device, with no transparency. Confirm exact pixels against Apple's specifications.

How many screenshots should I upload? Three to five strong ones, with your two best first, because most people never swipe past the first two.

## Frequently asked questions

### Do I need a paid generator to make App Store screenshots?

No. App Store Connect accepts any correctly sized PNG or JPEG, so you can frame and caption screenshots in free tools like Figma, Canva, or Keynote and upload them directly. Paid generators are a convenience, not a requirement.

### What is the best free App Store screenshot generator?

The best free path is to start from a polished screen rather than a template. VP0, the free iOS design library for AI builders, gives you that screen, then you capture it in the Simulator and frame it in any free tool. A great screen in a plain frame beats a weak screen in a glossy one.

### What screenshot sizes does Apple require?

Generally one large iPhone size in the 6.9-inch and 6.7-inch class and one 13-inch iPad size if you support iPad, up to 10 per device, in PNG or JPEG with no transparency. Apple updates exact pixels when new hardware ships, so confirm against the official specifications.

### How many screenshots should I upload?

Three to five strong ones, with your two best first. Most people never swipe past the first two, so put your clearest benefits there and treat the rest as supporting evidence.
