QuireWhat the “Please wait” PDF message means, and how to open the form
Short answer: the PDF is an XFA form (also called a dynamic form), an older Adobe format that most PDF viewers can’t display, including those in Chrome, Edge and Preview. Save the file to your computer, open it in the free Adobe Acrobat Reader desktop app, fill it in there and save it.
Nothing is wrong with your computer, and waiting won’t help: the message is the only thing other viewers can show.

The message
The page usually reads: “Please wait… If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document.” It goes on to suggest upgrading Adobe Reader.
The form inside is written in XFA (XML Forms Architecture), which Adobe created. The PDF carries the placeholder page for viewers that don’t understand XFA, which is most of them. A reply marked as the correct answer on Adobe’s community forum explains that this message in a browser most likely means a dynamic XFA PDF, and recommends downloading the file and opening it in Acrobat Reader or Acrobat. The University of Michigan’s help desk says the same.
Open the form in Acrobat Reader
- Save the PDF to your computer
If it opened in your browser, use the viewer’s download button, or go back and right-click the link and choose Save link as. Don’t print or save the “Please wait” page itself.
- Install Adobe Acrobat Reader
Get the free Acrobat Reader desktop app for Windows or Mac from Adobe if you don’t have it.
- Open the file in Acrobat Reader
Right-click the downloaded PDF and choose Open with (Open With on a Mac), then Adobe Acrobat Reader. Double-clicking may open it in your browser or Preview again.
- Fill it in and save
Fill in the form in Acrobat Reader and save it. Send or upload that saved file as the form asks.
Which apps can’t open XFA forms
- Chrome’s built-in PDF viewer and most browser viewers.
- Microsoft Edge, at least in its earlier PDF reader: Microsoft’s documentation for that reader lists XFA as unsupported. Edge’s current reader is built differently and we haven’t tested it with XFA.
- Preview on a Mac. A double-clicked PDF opens in Preview by default, so choose Open With › Adobe Acrobat Reader instead.
- Quire PDF, our Chrome extension: XFA forms aren’t supported. We’d rather say so here than have you find out halfway through a form.
Online converters that claim to turn XFA into a normal PDF exist, but they upload your form, and these are often government or tax forms with personal details. Acrobat Reader is free and runs on your computer.
If Acrobat Reader isn’t an option
- Ask the sender for another version. XFA is old: the PDF Association notes that it was deprecated in PDF 2.0, the current PDF standard. The organisation may have a standard fillable PDF or an online version of the same form.
- On a Chromebook, neither Gallery nor Chrome can show the form. Using another computer with Acrobat Reader is the reliable route.
Other reasons a form won’t fill
If you see the form’s pages but can’t type in them, it isn’t XFA. The form may have no fields at all (a scan or a flattened copy), in which case you can add text on top; see how to fill a PDF form in Chrome. Fields that calculate totals rely on scripts, which some viewers, including Quire PDF, don’t run.
Questions
Is the PDF broken or a virus?
No. The message is part of the file, shown deliberately to viewers that can’t render the real form.
Will the filled form open for the person I send it to?
It stays an XFA form, so it needs Acrobat or Reader at the other end too. Organisations that issue XFA forms generally expect that.
