Document Viewer

Note: This feature requires a paid plan.

Filestack offers a way to preview files in the browser combining our processing engine with a custom solution built on Mozilla’s PDF.js.

Supported file types:

PDF files (PDF)
Powerpoint files (PPT, PPTX)
Excel files (XLS, XLSX)
Word files (DOC, DOCX)
ODF word processing documents (ODT)
ODF presentation documents (ODP)
Image files (gif, tiff, jpg, jpeg, png)
HTML files
Plain text files
Adobe Illustrator and Adobe Photoshop files (AI, PSD)

Any file that is a PDF or supports being converted into a PDF can be previewed by using the preview processing task in the file URL:

https://cdn.filestackcontent.com/preview/HANDLE

This URL can be embedded in your page as a HTML iframe element, and our JavaScript client provides a convenient preview method to generate and embed these URLs.

For example:

<iframe style="width:100%;height:600px;"
        src="https://cdn.filestackcontent.com/preview/SGe380ViQ7W8efiX6sdG">
</iframe>

Document Slider

This is a premium feature. Please contact our Support Team.

Filestack also offers a way to preview files in the browser in a slide view. Any file that is a PDF or supports being converted into a PDF can be previewed by using our slide Processing API task:

https://cdn.filestackcontent.com/slide/HANDLE

You can pass in a solitary Filestack handle or an array of handles to be merged into one PDF document. This URL can be also embedded in your page as an HTML iframe element.

Note: This only works with Filestack handles.
