Mobile Pinch Zoom

Pinch with two fingers to zoom your notes in and out on Obsidian mobile (iPad / iPhone / Android).

Obsidian mobile has no built-in content zoom and no status bar, so this plugin adds:

• Two-finger pinch to zoom the note in/out (smooth, frame-throttled).
• Anchored zoom — the point between your fingers stays put while you pinch; commands zoom toward the viewport center.
• Trackpad pinch (ctrl+wheel, e.g. iPad Magic Keyboard) zooms too.
• Snap to 100% — ending a gesture within ±5% of 100% glides back to exactly 100%.
• Also zooms standalone PDF and image files opened in their own tab (works in either zoom mode); the PDF toolbar keeps its normal size.
• A floating 🔍 indicator showing the current zoom; tap it to reset to 100%. By default it stays visible while zoomed and fades out shortly after returning to 100% (configurable: auto / always / hidden).
• Commands Zoom in / Zoom out / Reset zoom with eased animation (assignable to hotkeys).
• Canvas and Excalidraw are left alone — they have their own pinch zoom.
• Figures keep growing (v0.8.0) — images normally stop at the pane edge (max-width: 100%), so a full-width figure would not get any bigger while the text grows. Now figures keep scaling with the zoom past the pane edge; swipe sideways inside the figure to pan (can be turned off in settings).

Desktop companion: on desktop use Ctrl+Scroll Zoom. This plugin activates only on mobile and no-ops on desktop.

Zoom modes (Settings)

• Content (default) — scales the whole note via CSS zoom (text + images + formulas). Smoothest, best in Reading view. In the editor the cursor may sit slightly off at non-100% zoom.
• Font size only — scales the text via font-size; since v0.7.0 figures (images, videos, Mermaid diagrams, Excalidraw embeds) zoom along with it, each growing up to the pane width. Solid in the editor.

Settings

• Zoom mode, zoom step (for the commands), minimum/maximum zoom
• Indicator: auto-fade / always / hidden, and position (any of the four corners)

Installation

Via BRAT (recommended for mobile)

Install the BRAT community plugin, then add hata-suriiken/obsidian-mobile-pinch-zoom.

Manual

1. Download main.js and manifest.json from the latest release.
2. Copy them into <your vault>/.obsidian/plugins/mobile-pinch-zoom/.
3. Reload Obsidian, then enable Mobile Pinch Zoom under Settings → Community plugins.

Notes

• Mobile only: isDesktopOnly is false so it loads on mobile, but the gesture logic activates only when Platform.isMobile is true.
• Content mode uses CSS zoom; the in-editor cursor position can be slightly off at non-100% zoom — switch to Font size only for heavy editing (figures still zoom there too).
