Prepare your first screenshot package
Images stay on your device while they are processed in this version of the tool.
Step 1
Upload screenshots
No screenshots selected.
Step 2
Choose an output
Preserve mode keeps the app UI proportional. If the screenshot shape does not match the selected store size, AppScreenSizer warns you instead of adding bars, padding, or stretching the screen.
Upload at least one screenshot to begin.
Step 3
Preview and download

Your formatted preview will appear here.
Simple workflow
From raw capture to ready-to-upload

GitHub, Android Studio, and Wear OS guides
Built from real project workflows: how to create a repository, bring a project onto a computer for the first time, and update the Android Studio copy you already have.
GitHub: create, clone, pull, push
First time from GitHub: use git clone. Already on your computer: use git status followed by git pull origin main. The full guide also covers creating your own repository, connecting an existing project, local changes, and common Git errors.
Wear OS: GitHub → Android Studio
Step-by-step instructions for cloning a Wear OS project into Android Studio, opening the correct project root, Gradle sync, selecting a Wear OS emulator, and later pulling new repository updates without downloading the whole project again.
Quick update routine
When a project is already cloned locally, open its terminal and run:
git status git pull origin main git log -1 --oneline
If local files have changes, commit or stash them before pulling.
