Paper Renamer

Auto-rename research PDFs on download, sort them into folders, and flag papers you already downloaded. Files stay on your device.

🎓 Paper Renamer — Smart PDF Renaming for Researchers Stop downloading papers called "fulltext.pdf". Paper Renamer automatically extracts metadata from academic papers and renames them with meaningful filenames the moment you download — no clicks, no manual typing. Your Downloads folder stays readable, sortable, and searchable. Before: download.pdf · paper.pdf · 1706.03762.pdf After: 2024_Vaswani_Attention_All_You_Need.pdf 🔒 Your PDFs stay on your device — no account needed to start renaming. 📝 KEY FEATURES ✅ Automatic Metadata Extraction • Title, authors, year, DOI, and journal — pulled straight from the page • Works on major academic publishers, preprint servers, and any site with standard citation metadata (Highwire, Dublin Core, etc.) ✅ Meaningful Filenames, Automatically • Default: {year}_{first_author}_{short_title}.pdf • e.g. 2024_Vaswani_Attention_All_You_Need.pdf • No more renaming papers by hand ✅ Auto-Organize into Folders (Free) • Optionally sort renamed PDFs into subfolders by journal or by year • Keeps a large library tidy with no manual filing ✅ "Already Downloaded" Badge (Free) • Open a paper you've saved before and a badge shows it — with how long ago and how many times — so you don't download the same PDF twice • Click to reveal the saved file in its folder ✅ Private Download History (Free) • An on-device record of the papers you've saved (never uploaded) • Powers duplicate detection; turn it off or clear it anytime in settings ✅ Reliable on More Sites (Free) • Recognizes downloads even when you open the PDF in the browser viewer first • Broad coverage across journals, preprint servers, and university repositories ✅ Customizable Templates (Pro) • Multiple saved templates with 12 variables: {title}, {short_title}, {year}, {first_author}, {authors}, {journal}, {doi}, {arxiv_id}, and more • Real-time preview before saving ✅ Site-Specific Rules (Pro) • Different templates for different journals, with URL pattern matching ✅ Advanced Author Formatting & Title Shortening (Pro) • "Smith", "Smith J", "J.
