5 Best File Viewer Widgets to Embed Files Securely on Websites

When you run a website, online store, or forum, you will encounter different circumstances to embed files on your site. In those cases, you will have to use a secure file viewer widget to upload and insert files into a page on your website.

In our previous guide on Top embeddable HTML PDF reader widgets for websites, you found tools you can use to embed any PDF document and add features such as download capability (or restrict downloading) and collaboration.

But what about other file formats such as DOCX (Microsoft Word document), AI (native Adobe Illustrator vector file), PPTX (Microsoft PowerPoint presentation), XLSX (Excel spreadsheet), and TXT (text document)?

How can you upload any file to your site so users can view them and download them?

That is why you should use an HTML file viewer widget on your site to embed files.

In this article, you will find out the best file embed widgets (some support 20+ file formats), features, live demos, and more.

Why should you use a file viewer?

  1. File viewer retains users on your site – Instead of using a file download option, using a file viewer widget on your website can increase user engagement and improve conversions. For example, embed Docx on your website instead of linking to your Google Docs document to increase user actions.
  2. Diversify content – Nowadays, Google and other search engines rank more than HTML pages on search engines. By diversifying content on your site, you will not only make your web page more engaging but also increase traffic from search engines. Plus, it’s easier to represent data using different file formats, such as XLSX, than using a plugin or other web widgets that will take more time to set up.
  3. Deliver more product info – Share technical documents, specifications, and instructions and let users know your product or service better.
  4. Increase Conversions – Entice users to take action by showcasing your supporting documents and product catalogs.
  5. Present data in the best way possible – Improve the professionalism of your business by presenting data in the most user-friendly and professional manner.

4 things to consider when using file viewer widgets on your site

  • Customize the widget – Most file viewer widget builders listed below allow you to insert multiple files and change the color scheme, fonts, widget size, and more. Make use of customizing tools to integrate the file embed widget with your site using the brand color palette, font families, etc. Before adding the widget to your site, preview it on the mobile view to ensure respective files are viewable.
  • Concern about the page loading speed – The last thing you want is to increase your site’s loading time because of the file reader widget! According to a report, page loading speed directly correlates with the conversion rate. You can load the file viewer widget’s script code (JS) asynchronously to load the widget after other contents are loaded on the page. Furthermore, you can use a script manager such as Google Tag Manager or Cloudflare Zaraz, limit the number of files shown on the file viewer widget and compress files (and content within files) before uploading files.
  • A/B test your landing pages – You will not know if adding a file viewer to a website results in increased conversions if you do not split-test your pages — experiment using different document reader widget variations (minimalistic view, full-width, etc.) and styles.
  • Use other conversion boosters – Using a file viewer widget on a site is not guaranteed to boost sales on your site. Utilize other techniques such as HTML countdown widgets (to entice urgency), Product comparison tables (compare your product with competitors and highlight USPs), customer testimonials carousels, progress bars, before and after photo sliders (to showcase performance before and after using your service/product), and high-converting checkout pages.
