How to save Iconize icons in note properties in Obsidian
As of October 2026, Iconize keeps the icon that you pick with Change icon in its own data file, not in the note. Iconize can read an icon from a property, but its picker does not write one. A plugin can copy each icon into the note properties and keep them current.
Icon Frontmatter Mirror has Pro, and $15 one time turns it on in all 129 plugins.
Background
Iconize issue 380 asks for an option that makes the add-on write the icon to the frontmatter. Its first post wants Change icon to set the frontmatter when Use icon in frontmatter is on. An icon in the note travels with it through sync, copies and search.
2 ways to do it
Type the icon property by hand
Add the
iconproperty to a note and type the icon name that Iconize uses, such asLiBookOpen. With Use icon in frontmatter on in Iconize, Iconize reads the icon from that property.This works note by note, and you can add
iconColorfor a color.- limits
- You copy each icon name yourself. An icon that you later change with the Iconize picker goes only to its data file, so the property gets out of date.
Icon Frontmatter Mirror from this site
Icon Frontmatter Mirror reads the Iconize data file and writes each note icon to the
iconproperty, and its color toiconColor. It checks the file every 2 seconds by default, so a change shows in 2 to 4 seconds.It never writes the Iconize data file. A note that already has another value goes to a conflict list, and the plugin does not change it.
- limits
- Folders have no properties, so folder icons are skipped. Writing the icon to more properties or to folder notes needs Pro.

Common questions
Does Icon Frontmatter Mirror change the Iconize data file?
No. It only reads that file. It writes to your notes through the frontmatter API of Obsidian, and only when a value must change.
What happens to the property when I remove an icon in Iconize?
The plugin removes the property only if it still has the value that the plugin wrote. A value that you typed stays. If one check would remove values from more than 10 notes, it holds the removals and shows a notice.
What if a note already has its own icon value?
The plugin does not overwrite it and puts the note in a conflict list. Run Show icon conflicts to see each note value next to the Iconize value. You can then replace them or keep the note values.
