Make Your App Store Screenshots Look Like a Pro Made Them

Plain screenshots do not sell your app — polished ones do. Upload your screenshots, pick a background, text color, font and border you like, add a short headline for each screen, and download App Store-ready iPhone or iPad images in one click. No design skills needed, no software to install, and your images never leave your browser — it is completely free with no sign-up.

What You Can Do

  • Decorate every screenshot in one pass — upload them all together instead of editing one by one.
  • Find a look that fits your brand — try different background, text and border combinations, or pick your own exact colors.
  • Cover both iPhone and iPad listings — switch devices and export the exact size the App Store expects.
  • Add headlines that explain your app — write a title and subtitle for each screen and see it update instantly.
  • Get the order right — drag screenshots into the sequence that tells your app's story best.
  • Fill in all your captions at once — paste a list of titles and subtitles instead of typing each one.
  • Skip the writer's block — export one combined image and hand it to an AI to draft captions for you.
  • Download and go — export one screenshot or your whole set, ready to upload to App Store Connect.

Who Is It For

If you are an indie developer, a solo founder, or part of a small team getting an app ready for launch (or refreshing screenshots for an update), this tool gets you from raw screenshots to a finished, on-brand listing in minutes — no designer required.

How To Use

  1. Pick a device (iPhone or iPad), upload or drag in your app screenshots, and drag the list to reorder if needed.
  2. Mix background color, text color, font and border until you like the look.
  3. Fill in the title and subtitle for each screenshot by hand, or use the "Generate captions with AI" flow below to do it in bulk.
  4. Click "Export All" to download every App Store spec JPEG.

Let AI Write Your Captions (Recommended)

Staring at a blank title field? Skip it. Have an AI that can read images (like GPT-4o, Claude or Gemini) look at your screenshots and write all the captions for you at once. Here is how:

  1. Click "Export Grid". The tool stitches every screenshot into one ordered grid image and downloads it, and pops up a ready-made prompt — click "Copy Prompt" to grab it.
  2. Open any chat with a model that can read images, upload the grid image you just exported, and send it along with the copied prompt.
  3. The model will write, for each screenshot in order, an object with a title and subtitle, and return a JSON array (English captions by default, suited for App Store listings aimed at overseas markets).
  4. Paste the JSON array the model returned into the "Batch Copy" box on the left, click "Apply in Order", and every screenshot's caption gets filled in at once.
  5. Once the preview looks right, click "Export All".

That way, going from raw screenshots to a finished set with captions usually takes a minute or two — the most time-consuming part, writing captions from images, is handed off entirely to AI.
