PixelPinch
Token-light screenshots for AI chat. Capture, shrink, and copy, straight to your clipboard, ready to paste into ChatGPT, Claude, or Gemini.

⌘⇧8
Capture a window. Click to select.
What it does
Built-in macOS screenshots are huge, and vision-capable LLMs charge you image tokens for every pixel. PixelPinch sits in your menu bar and rebinds the standard screenshot keys to a smarter pipeline: capture, downsize, JPEG-compress, and write straight to the clipboard.
The result is a screenshot that looks identical to a human at chat resolution, but costs roughly 4× fewer tokens to send to an AI. No round trip through Preview, no manual export, no third-party services.
Features
Two global hotkeys. Region and window capture, both rebindable.
Configurable resize & quality. Tune the resolution cap and JPEG quality from Preferences.
Optional backup save. Keep a full-resolution copy on disk if you want one.
Launches at login. Lives quietly in the menu bar, ready when you need it.
No telemetry, no network. Everything runs locally on your Mac.
Requirements
macOS 13 (Ventura) or later. Apple Silicon or Intel. Requires Screen Recording permission on first run; macOS will prompt you.
