GalleyA Lightweight PDF Previewer
for TeX/LaTeX on macOS
Galley removes unnecessary toolbars and status bars so you can focus on your document. Designed with TeX/LaTeX authors and typesetters in mind.
Built for the Edit–Compile–Preview Loop
Auto-Reload
Monitors the PDF for changes and reloads automatically, preserving scroll position and zoom level.
SyncTeX Integration
Forward Search jumps from your editor into the PDF. Cmd+Click jumps back. Works with Emacs, VS Code, and custom editors.
Character Inspection
Right-click selected text for Unicode, font name, family, point size, vertical metrics, and Glyph ID (with CID for CJK).
Why Galley?
Most PDF viewers are general-purpose readers, not optimized for the edit–compile–preview cycle of TeX/LaTeX work. Galley is built with native macOS technologies (PDFKit, AppKit) and has no external dependencies, resulting in a small binary and fast startup.
It does not try to be a general-purpose PDF reader. It aims to be a reliable companion for your text editor, updating your document in the background as you write.
