Valuable content in your PDFs is now just a click away. Link to PDF pages, table of contents, and even your PDF annotations!

PDFoo opens up access to your PDFs:
• Research, summarize and link to content in PDFs
• Search PDF and link to results from anywhere
• Export annotations with links back to the PDF to preserve context

PDFoo URLs work in popular note-taking apps that support rich text such as OneNote, Curio, DEVONthink, and Scrivener. For a fuller list of compatible apps, and how to make the most of PDFoo, visit the support website.

PDFoo can also generate URLs in markdown format, for linking to your research in PDFs from writing apps such as Bear and MWeb.

Two popular note-taking apps, Evernote and Ulysses, are not supported out-of-the-box, but neat workarounds exist and are provided on the support website.

What’s New

Version 1.5

• New option in Preferences > Behaviors: whether to automatically validate the Prefix and PDF links saved within the app. If so, the Prefix table will highlight in red the PDF links that are broken because the PDF file was moved or deleted. By default, automatic validation is now disabled. This prevents a situation where PDFs may have been linked on a network drive that has since become unavailable, and causes macOS to inconveniently prompt you to reconnect the drive when PDFoo opens. Whenever automatic validation is disabled, a "Validate" button is shown in the Prefix tab of PDFoo preferences to allow you to manually validate the links to PDF files on disk.
• PDFoo now supports Dark mode on macOS Mojave and later.
• The PDF > PDF Display menu now has the option to display the PDF in book mode, which works great with either the "Two Pages" or "Two Pages Continuous" modes. For best results, use the "Collapse" button on the PDFoo toolbar to collapse the scratchpad and table of contents panes, to view the PDF clearly while browsing and extracting notes with PDFoo links.

A Researcher or Doctoral Candidates Dream

I use this in conjunction with DevonTHINK Pro, Evernote and other notes apps for digesting and pulling specific lots of different, and often lengthy, pdf files. It is great being able to extract specific information, include in whatever app I’m working in, and have a link back to the original source pdf. If you work with information and authorities spread across a large volume of pdfs and you have diverse issues you’re tracking, this software is a great tool to have in your box.


Works Now

I did a prior review and said it didn’t work. The program has been fixed by its makers, and it now works great.

Not a 1 ,

Might be a Good App but it’s a Terrible Tutorial Video

Please! Your tutorial video is terrible. It’s way too fast and the man’s English (a worker at the company?) is almost indecipherable. You may have a good product (although from the tutorial it’s not clear what it does) so spend a few hundred dollars on producing a decent tutorial video. First, explain (and SHOW) what PFDoo does and why this helps people. Then, EXPLAIN (in clear English) how it works. I’m sure the man is a great programmer, but presentations in English are not his strong point!
