![]() ![]() LiquidText (note: there is a LiquidText glitch where you must do all of your highlighting in a single session).Thus far, we've had positive results with the following apps (provided you are working with a clean PDF to begin with): Use the concatenation feature described here: How to Combine Highlights On-the-Fly with Readwise. What happens if a highlight spans two pages?ĭue to limitations of the PDF file format, the highlight will be broken into two separate highlights. The absolute worst are PDF presentations with text all over the page. You can still extract highlights from multi-column PDFs: just be prepared for things to sometime fall out of order. Text in a single column extracts much better (read: much better) than two or three column PDFs. Highlights extract much cleaner from digital PDFs than scanned PDFs with OCR applied. PDF is a fickle file format, so some PDFs highlight better than others: You can also upload PDFs by selecting the PDF Import option from Add Highlights. To import highlights from a PDF, simply email the highlighted PDF file as an attachment to an email address associated with your Readwise account). We plan to support other ways to export annotations in future updates.Yes! But please note that support for PDF highlights is in perpetual beta so you may discover a new bug from time to time (which we will promptly attempt to fix). When exporting metadata (e.g., BibTeX or RIS) from your library, there's an “Include Annotations” option under “Export Files” that will embed annotations in all exported PDFs. (To export the original file, drag the attachment item from the items list to your filesystem or use right-click → Show File and copy the file from there.) You can export a copy of the PDF with annotations embedded by using File → “Export PDF…” from the library view or “Save As…” from the PDF reader. (Early versions of Zotero 6 included a “Store Annotations in File…” option as well, but it could result in file conflicts and lost data, and it was removed.) The annotations are removed from the PDF to avoid conflicts and duplicates. External annotations are read-only by default - indicated by a lock icon - but you can transfer them into Zotero by selecting File → “Import Annotations…” from within the PDF reader, after which they'll be fully editable. While Zotero saves its own annotations to its database, it's possible to interact with annotations embedded in a PDF file in much the same way, as well as to export PDFs with embedded annotations.Įmbedded annotations show up in the Zotero PDF reader, and you can add them to Zotero notes in exactly the same ways as Zotero-created annotations. We'll always try to support external workflows as efficiently as possible, but it will never match the seamless experience we're able to provide when everything is done within the app. It's also harder for Zotero to track changes to external files, so if you annotate something externally, there may be a delay before you can search for those annotations in Zotero or before the updated file syncs - you might need to wait for Zotero to notice the file modification or manually trigger reprocessing and syncing. For syncing, as discussed above, saving annotations back to the file requires Zotero to transfer the entire file - which could be many megabytes - after every change, whereas transferring just an individual annotation is instantaneous. There are major performance benefits as well. ![]() We plan to add other extended features like this going forward. Storing annotations in the database also enables advanced functionality, such as being able to tag annotations and filter for them throughout the Zotero interface. This happened regularly in earlier versions of Zotero, both in personal and group libraries, and we expect PDF annotation to get far more usage as part of the app. By contrast, with standard PDF annotations, the entire PDF file needs to be transferred after every change, so if two people in a group added an annotation at the same time, or even if a PDF was just left open on one computer, it would create an unresolvable file conflict, forcing the user to choose one side or the other. With annotations stored in the database, Zotero is able to quickly sync just the details of each new or updated annotation.
