I've released two of my plugins on the official Community Plugins store, both aimed at making zooming in Obsidian easier. Both are free and open source (MIT).
■ Ctrl+Scroll Zoom (Desktop)
Zoom the entire Obsidian window with Ctrl + mouse wheel, just like web browsers or VS Code. Unlike image-only zoom plugins, it scales the whole interface — UI and note text together — via Electron's page zoom. Trackpad pinch-to-zoom is supported too.
- Ctrl + wheel up to zoom in, down to zoom out
- Zoom level persists across restarts
- Status-bar indicator shows the current zoom % (click to reset to 100%)
- Command-palette commands for zoom in / out / reset (assignable hotkeys)
- Configurable zoom step, min/max limits, and an option to hide the indicator

■ Mobile Pinch Zoom (Mobile: iPad / iPhone / Android)
Mobile Obsidian has no built-in content zoom — this fixes that. Pinch with two fingers to smoothly zoom your notes in and out.
- Two-finger pinch zoom (frame-throttled for smoothness)
- Also zooms standalone PDFs and images
- Floating 🔍 indicator shows the current zoom level (tap to reset to 100%)
- Commands for zoom in / out / reset (assignable hotkeys)
- Two modes: Content (scales the whole note via CSS) and Font size only
- Customizable zoom mode, step, min/max, and indicator position

How to install
In Obsidian, go to Settings → Community plugins → Browse, search for the plugin names above, then Install and Enable. Use Ctrl+Scroll Zoom on desktop and Mobile Pinch Zoom on phone/tablet for comfortable zooming everywhere. Feedback is very welcome!
