+# 🗒️ PVE NoteBuddy
+
+Live: https://jangajones.github.io/pve-notebuddy/
+
+PVE NoteBuddy is a lightweight web app for generating clean HTML snippets for Proxmox VE Notes.
+
+It helps you build note blocks (icon, host data, config paths, custom notes) with quick formatting controls and live preview.
+
+It also solves the common PVE Notes image sizing issue by pasting a link to an SVG icon and extracting the svg code with the option to scale the image.
+No external CDN, all offline, no separate editing, vector quality :)
+
+It’s fully client-side in the browser.
+No backend is used, and no data is sent by the app itself.
+Only if you provide an external icon URL, the browser does fetch that image/SVG directly from that external host.
+
+One of the many notes I made with this tool in a few seconds:
