Migrate from Mendeley

Import your existing Mendeley library directly into Paperpile. The steps differ depending of whether your library is fully synced online or not.

If your library is fully synced online

If you keep all your articles and PDFs synced in Mendeley, Paperpile can automatically import your Mendeley library and PDFs from the web.

  1. Open the menu
  2. Choose Import from other Programs
  3. Follow the on-screen options

If your library is not synced

Your Mendeley library and PDFs can still be imported with a few easy steps:

  1. Select all papers in your Mendeley library and choose File > Export... . Change the format to RIS-Research Information Systems and save to your desktop (see image below).
  2. Find the folder where your Mendeley PDFs are stored by right-clicking on an item with a PDF and choosing Open Folder. Navigate to the folder that holds all of your Mendeley PDFs, and keep that folder open for the next step.
  3. In Paperpile open the menu, choose Upload Files and add both your exported RIS file and your entire Mendeley PDF folder to the upload dialog. Click Start upload to begin.
  4. Paperpile will import your library and attach all existing PDFs to their correct articles when possible. When the import is complete, double-check any articles marked as incomplete or duplicates to help keep your library clean.


  • Too many duplicates were encountered during import: This message will occur if you attempt to import a web library with many papers that are identical to items already in your library. Most likely, your web library has already been imported, in which case you should delete your existing imported folder before re-trying the import. (Note: Paperpile does not sync papers with Mendeley or Zotero — library import should only be run once!)
  • An unexpected error occurred: This message may be shown if the Zotero or Mendeley web service is unavailable, or if an unrecoverable error occurred while downloading data from their external servers. Wait a few minutes before trying again, and if the error persists please contact support@paperpile.com .
