How to upload and embed a PDF flipbook to Squarespace

Tuesday 3rd July 2018

This brief tutorial will go through the steps of uploading and embedding a PDF document as a flipbook (such as a catalog, magazine or brochure) to your Squarespace website. FlowPaper provides a range of optimizations and settings to your PDF documents so that your visitors are able to view your publications as fast and seamless as possible on all devices and browsers.


Make sure you have the FlowPaper Desktop Publisher installed on your Mac or PC before proceeding with this tutorial.

Step 1 – Uploading the publication to FlowPaper cloud

Make sure you have style and configured your publication so that it is ready for upload. Click on the ‘Publish’ button in the top right corner of the desktop publisher and proceed to use the ‘Share on FlowPaper cloud’ option to make your publication available online. This should give you a public URL starting with which can be used to view and share the PDF online.




Step 2 – Add the code block to your Squarespace web site

Switch over to your Squarespace website and click “add block” in the top right corner.

The type of block you should be adding is a so-called ‘Code’ block. The easiest way of finding it is by searching for ‘code’ in the block dialogue that pops up as shown below:




Step 3 – Add the code and update the URL to your publication

The last step of embedding the publication is to add the code snippet that adds the publication to the page. Copy the code snippet below and paste it into the HTML text box. Then update the URL in the snippet to the URL that you received after uploading your publication to FlowPaper cloud (marked in bold).

<iframe frameborder="0" width="100%" height="500" src="" type="text/html" scrolling="no" allowFullScreen></iframe>

The publication will show up at the position where you have added your block as seen below. Tada! All done!

Export PDF content into responsive digital editions with FlowPaper 3.2.0

Saturday 9th June 2018

We have added an entirely new web page builder which lets you export content out of your PDF documents into responsive web pages, ePub publications and as packaged apps. The template is available via the dashboard (‘Web Page Builder’ for web page exports and ‘Digital Edition’ for cross-platform distributions) and exports your content in HTML5 format with fonts and graphics fully preserved. This new template speeds up the process of creating digital editions for magazines and other publications with rich layout.

Double click or drag texts, images and user defined areas right out of your PDF documents into fully responsive editions. Export as ePUB3, native apps as well as web editions.

Please feel free to contact us if you have any questions around how to use this template or how to publish your responsive editions as apps. We’d be more than happy to arrange a demo over Skype or similar to get you started.

Monday 14th May 2018

We’re at the finalising stages in our implementation of a new export template which will allow you to extract pages from PDF documents and create re-flowable/responsive publications in a much more time efficient and user friendly manner. We have been investing lots of time in the period February to May to make this release as stable and useful as possible but we want to spend a bit of extra time just to make sure this release gets to you in the best form and shape possible so we’re extending our release cycle a bit for this version.

Have a look at a sneak preview below of whats possible in the upcoming version!
