Image Tab Zoom

An Obsidian plugin that adds pinch-zoom and modifier-scroll zoom to image files opened in Obsidian. Works on both desktop (macOS trackpad pinch, Cmd/Ctrl + scroll) and iOS (native pinch).

Scope

Only affects image files opened directly in Obsidian (.png, .jpg, .webp, etc. in their own tab). Images embedded inside markdown notes are not touched.

Features

• Trackpad pinch-to-zoom on macOS.
• Two-finger pinch-to-zoom on iPad/iPhone, with two-finger pan during the pinch.
• Modifier + scroll wheel zoom (Cmd, Ctrl, either, or no modifier).
• Drag to pan when zoomed in, clamped to the image's edges.
• Double-click (or double-tap on touch) to reset zoom.
• Cursor-anchored zoom — the point under your cursor stays put.

Install

Settings

• Modifier key for scroll-zoom — which modifier must be held while scrolling to trigger zoom (Cmd, Ctrl, either, or none).

• Maximum zoom — upper scale bound.
• Reset on double-click — whether double-clicking resets zoom to 1x.
