Features
Everything you need to ship screenshots
A complete, professional pipeline — from drop to validated, organized, exported set.
Automatic device detection
Drop a screenshot and instantly see its platform, device, resolution, orientation and aspect ratio — matched against the live Apple device library.
App Store validation
Every image is checked for correct resolution, aspect ratio, orientation and file size, with clear pass / warn / error badges before you export.
Fit, Fill, Pad & Stretch
Choose how images map to each size, with padding backgrounds: white, black, transparent, gradient, a blurred screenshot, or any custom color.
Batch processing
Resize 10, 100 or 1000+ screenshots at once. Web Workers keep everything parallel and smooth, with a live progress bar — the UI never freezes.
Smart conversion
Upload one size and the toolkit suggests every compatible App Store size you can safely export to — and explains when a conversion isn't recommended.
Screenshot organizer
Reorder, rename, duplicate, delete and multi-select with drag & drop and keyboard shortcuts before you generate the final set.
Clean ZIP export
Download a tidy AppStoreScreenshots.zip with per-device folders (iPhone-6.9, iPad-13, VisionPro …) and your original or sequential filenames.
Total privacy
No backend, no accounts, no cookies, no analytics. Images are decoded and resized on your device and never leave your computer.
Your screenshots never leave your computer
There is no server to send them to. The entire toolkit is static files and Web Workers running in your browser, so your unreleased app screens stay completely private.

FAQ
Questions, answered
No. Every image is decoded, resized and zipped entirely inside your browser using Canvas and Web Workers. Nothing is ever sent to a server — there is no server. You can even disconnect from the internet and it keeps working.
