PDF Metadata Refresh

by git-jiwon · github.com/git-jiwon/zotero-pdf-metadata-refresh

Re-recognises metadata for PDFs already in your library using Zotero's recogniser, DOI and ISBN lookups, catalogues, web search or a local LM Studio model.

PDF Metadata Refresh has Atlas grade B (use with care) because it contacts servers we couldn't identify: www.aladin.co.kr, www.nl.go.kr and www.yes24.com, and 3 more findings. It works with Zotero 10. Last checked 6 Nov 2026.

Downloads a .xpi file (0.7 MB). In Zotero, open Tools → Plugins and install it from the file.
In useAn estimate of how many copies of Zotero have it: Zotero downloads each new version once for every copy that has the plugin, so we count the downloads of its most-downloaded recent release. Rounded. Plugins that update from outside GitHub count low.
68
DownloadsAll-time downloads of its release files from GitHub, counting every update. Installs from elsewhere aren't counted.
70
ReleasesVersions published on GitHub. Everyone who has the plugin downloads each one again, which adds up in Downloads.

What it does

Written by AI from the README

Re-recognises metadata for PDFs already in your library using Zotero's recogniser, DOI and ISBN lookups, catalogues, web search or a local LM Studio model. Shows proposals field by field, applies chosen changes and keeps undo history.

Old library entries often have wrong or missing metadata. This lets you review and fix many at once without losing attachments, notes or annotations. Korean and English interface.

What you'll need

Your rating of PDF Metadata Refresh v1.0.1

Your review is public, under the name you give, and published with the directory's data under CC BY 4.0. Links are removed. We never store your IP address: a scrambled code made from it is kept for 30 days to catch fake reviews. Every review is checked before it's published; how fake ones are spotted isn't published, so it can't be gamed.
