App Screenshots Generator & Editor

This screenshot creation tool is one of the many utilities available in Progressier, our all-in-one PWA toolkit. We made it available on this page for free, because we weren't satisfied with the existing alternatives. There are similar tools, but they tend to have features behind paywalls and/or add watermarks to your screenshots. With this tool, your screenshots are rendered without watermarks. As long as all you need is screenshots, it's completely free.

You can add screenshots to your app manifest to showcase your app in action. Screenshots are displayed during the installation process as part of the install prompt (see example). Screenshots are optional but a PWA that has screenshots tends to look more native and get more installs.

In your manifest, screenshots are an array of objects, each representing a single screenshot. You can see the parameters of the screenshot object here. You can use this tool to create, design and export screenshots. Host each of the screenshots on your server and link to their URL in your screenshot object array.

If you're using Progressier, your PWA screenshots are automatically hosted and added to your app manifest for you for free.

PWA screenshots must be image files in either .PNG or .JPG format. JPG is generally a better format to use for PWA screenshots as they're smaller in size and will be fetched faster.

The tool includes mockups of an iPhone 18 Pro Max, iPad Pro, Google Pixel 11, Samsung Galaxy S26 as well generic unbranded phones.

By default, screenshots created with our tool are 1080x1920 pixels in .jpg format. The official specs don't require a specific size. The width and height of your screenshots must be at least 370px and at most 3840px. The maximum dimension can't be more than 2.3 times as long as the minimum dimension. So screenshots can be landscape, square or portrait. However, every screenshot in a set must have the same aspect ratio. Only JPG and PNG image formats are supported.

There isn't an actual limit per se. But displaying more than 6 or 7 is generally not recommended. Keep in mind that more screenshots means more image files for the browser to download and more images for you to manage.

The screenshots property of the app manifest does not directly allow you to configure different sets of screenshots for different languages. However, with Progressier, you can create multiple sets of screenshots to display when a specific language, a specific OS, or a combination of both, are in use.

Sure! After you've created the screenshots and exported them, you can upload the raw file of the project on this page again to pick up where you left off.

Not necessarily, but they must all have the same aspect ratio. If they're in different aspect ratios, only screenshots that are in same aspect ratio as the first will be displayed.
