How to:

  1. install: on a computer with FileMaker Pro 19 or newer installed, click the Install your add-ons button on your confirmation e-mail
  2. relaunch FileMaker Pro
  3. in layout mode, open the add-on panel on the left
  4. click the + button and add the add-on to your custom app
  5. drag the add-on icon onto your layout
  6. double click the web viewer object. It's pre-configured with a custom function.
    1. the first parameter, _file, expects a container field or a variable containing a binary file (container)
    2. the second parameter, _parameter, allows you to pass various options (more will be implemented in future releases). For now options are for Audio/Video media only. Parameters should be passed as ¶ delimited list like: List ( "autoplay" ; "controls" )
      1. autoplay: play the video/audio media on record load or on insert
      2. controls: display the controls to play/pause…


  • display single/multiple page PDF files in full width
  • display images (jpeg, gif, png)
  • display svg
  • display json files (pretty)
  • display text files (txt, csv, tab, log…)
  • display html
  • display audio / video. Option to display controls and autoplay.


  • Important notice: this PDF viewer is purposedly super simple. There is no feature such as thumbnails, comments, zoom, search… The second parameter of the custom function might be used in future releases to add these features optionally, but for now (version 1.2, they are not included)
  • 1MT PDF Viewer relies on the native Web Viewer object, therefore all limitations are inherited, such as:
    • on Windows, will always display in foreground
    • cannot be inserted in a portal object
    • if inserted in a popover of which the button is in a portal, will display the first related record. To work around this limitation use this formula:
      Ω1MT_pdfViewer ( GetNthRecord ( relatedTable::container ; Get ( ActivePortalRowNumber )) ; "" )
    • This will work because opening the popover will make the row active. Note: if the portal is sorted, the result will be inconsistent. In this situation choose to sort the relationship rather than the portal object.
