How to download undownloadable PDF from Heyzine flipbook (as of June 2025)

(Seriously?)

The following instructions are for Chrome, user may perform similar actions when using other browsers

  • Step 1: F12 inspect the flipbook page
  • Step 2: Go to Application then Session storage and click on https://heyzine.com and you should see this: image
  • Step 3: Get PDF url from the Key column. Original key should be something like hz_cache_1201_p_10_normal_https://cdnc.heyzine.com/files/uploaded/v3/[REDACTED].pdf.
  • Step 4: Your PDF is at https://cdnc.heyzine.com/files/uploaded/v3/[REDACTED].pdf
  • Step 5: Enjoy!

Ending words

Heyzine should implement something more serious if they want to hide the PDF from user. I originally take a look at the Network tab, but the images are all in blob and I originally thought of writing a script to download them and convert to PDF. But then I take another look around and found the PDF URL in the session storage.
