A reflowable document is a type of electronic document that can adapt its presentation to the output device. Typical prepress or fixed page size output formats like PostScript or PDF are not reflowable during the actual printing process because the page is not resized. For end users, the World Wide Web standard, HTML is a reflowable format[1] as is the case with any resizable electronic page format.
In contrast to end user terminology, the notion of reflow is sometimes used to discuss desktop publishing program features for print publication page layout such as automatically balancing the amount of text in a number of columns.[2]
Reflow is not limited to text; 21st century scorewriters enable music notation to be reflowed between systems and pages in a similar way to how text reflows between lines and pages.

Transcription
This is a PDF document with a layout table in the document, and some users need to magnify their screen in order to read the content, which you can do directly within Adobe Reader. But users who have mobility impairments, or sometimes low vision users, et cetera, will need to have the text read in a way that there is no horizontal scrolling. With the document not re-flowed, it is difficult to read because I have to find where the horizontal scroll bar is or use my keyboard commands using the arrow keys and slowly move back and forth across the document to read each line of text. This gets tiring on the eyes and it can be difficult to keep your place in the document. To address this in Adobe Reader, we can have the document re-flow, which just means that it puts all the content on one screen with no horizontal scroll bar. So in this case, the text is wrapped around from line to line so that you can vertically scroll through the document but you don't have to horizontally scroll. This makes it easier for many users to read the document.
Examples
Besides HTML, commercially available systems include:
- EPUB is a simple reflowable format that allows a single column with inline images, in many ways similar to a stripped-down HTML.[3]
- Windows Presentation Foundation (WPF) introduced XAML-based documents together with a viewer call "SinglePageViewer" that can reflow any WPF objects. However the XPS document standard also introduced by Microsoft with WPF does not support reflow.[2]
- Tagged PDF documents can contain an additional data layer that (among other things) allows content to reflow within the boundaries of one original page.[4][5]
- FictionBook is a free reflowable format by design. It does not specify the appearance of a document; instead, it describes its structure. For example, there are special tags for epigraphs, verses and quotations.
- Amazon's Kindle File Format, but only in its newest version.[6]
Xerox PARC has developed an experimental system that allows the reflow of any document using OCR layout analysis at word-level.[1]
