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 ✅ Searchable Paper Library (Free) • A built-in page listing every paper you've downloaded — search by title, author, journal, or year • For each paper: open the saved file, revisit the source page, or copy a BibTeX citation; see how many duplicate downloads you've avoided • Stored on-device only (never uploaded); powers duplicate detection; turn it off or clear it anytime in settings ✅ Bulk Export (Pro) • Export your whole library — or just your current search — to BibTeX (.bib) or CSV, ready for your reference manager or a spreadsheet ✅ 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 ✅ Rescue Existing PDFs (Free) • Already have papers saved as "fulltext.pdf"? Pick one and Paper Renamer identifies it on your device, then saves a correctly-named copy • The PDF is read locally to find its DOI / arXiv ID / PMID — your original file is never modified and never uploaded • Optional: automatically identify a download that couldn't be named the usual way (experimental — off by default; enable it in settings) ✅ English & 日本語 Interface (Free) • The Settings page is available in English and Japanese — it follows your browser language and can be switched anytime ✅ 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. Smith", "John Smith", et al. support • Stopword removal, acronym preservation (DNA, RNA, CRISPR), CamelCase ✅ On-Device AI (Pro, experimental) • Optional Gemini Nano integration for smarter title shortening • Requires Chrome's built-in AI; availability depends on your browser and device • Runs entirely on-device — no data leaves your computer 🔒 PRIVACY-FIRST DESIGN • Your PDFs are never uploaded — all renaming happens in your browser • Core renaming is free and requires no account or personal data • No tracking, no analytics, no third-party ads • Optional Pro sign-in uses your Google account only to manage your subscription • The only network requests are unauthenticated metadata lookups (e.g. DOI via Crossref, arXiv, and PubMed) used to identify a paper — your PDF files are never sent • Your download history is stored only on your device and is never uploaded • Settings stored locally · Source available on GitHub 🎯 COMPATIBILITY • Major academic journal websites • Preprint servers • University repositories • Any site using standard citation metadata (Highwire Press, Dublin Core, etc.) 🚀 EXAMPLE OUTPUTS Default template: {year}_{first_author}_{short_title}.pdf download.pdf → 2024_Vaswani_Attention_All_You_Need.pdf paper.pdf → 2023_Brown_Language_Models_Few_Shot.pdf 1706.03762.pdf → 2017_Goodfellow_Generative_Adversarial_Networks.pdf Custom templates (Pro): {journal}_{year}_{first_author}_{short_title}.pdf → Journal_2024_Smith_DiffusionBasedSegmentation.pdf 💡 HOW IT WORKS 1.
