Screenshot S3

Automatically upload every screenshot you take to an S3 bucket. Then automatically copy the link to your clipboard.

A tiny macOS menu bar app that lives in your menu bar, watches for new screenshots, and handles everything — instantly and silently.

Everything you need, nothing you don't

Automatic Upload

Screenshots are detected and uploaded to S3 the moment they're saved. Zero manual steps.

Clipboard URL

The public link is copied to your clipboard instantly. Just paste it wherever you need it.

Built-in Gallery

Browse all your past uploads in a beautiful gallery. Re-copy links or open them anytime.

Menu Bar Native

Lives quietly in your menu bar. No Dock icon, no windows — just a clean, native macOS experience.

How it works

Use macOS shortcuts like Cmd+Shift+4 as you normally would.

Auto upload

Screenshot S3 detects the new file and uploads it to your S3 bucket.

Link copied

The public URL is on your clipboard. Paste and share immediately.

Your keys never leave your machine

Just input your AWS access key and secret key — that's all it takes to get started. Your credentials are stored locally on your Mac and are never sent anywhere except directly to AWS. No middleman, no server, no account to create.
