Show HN: App Screenshot Kit – App Store screenshots from raw images

App Screenshot Kit converts raw ios screenshots into ios App Store compliant image sets. It removes the usual workflow of importing into a design tool, placing into device frames, resizing for every requirement, and fixing pixel mismatches.

Why I built it

I kept running into App Store rejections caused by single-pixel errors after exporting from Figma. I also noticed frequent posts from developers dealing with the same issue, especially around maintaining consistent sizes across devices. It felt like a simple formatting task that had become too dependent on design software.

I wanted a way to go directly from raw screenshots to final exported sets without opening a design tool.

How it works

Upload iOS screenshots (PNG/JPEG)

Pick a device frame

Add optional headline text

Export all required sizes in one batch

No account required

What’s different

Most screenshot tools either require account creation, rely heavily on template editors, or depend on a Figma/Canva workflow. This tool tries to handle the entire formatting process directly from the browser with minimal steps.

Looking for feedback

Any device frames or formats that should be added?

Does the export flow cover the sizes you typically need?

Are there pain points in your own App Store screenshot process that this should solve?

Would support for Google Play be useful?

Happy to answer technical questions.

Cheers
