PDF Reader strange behaviour!

Hi Thunkers,
I’m facing some troubles with “PDF Reader”…

In short, with “WEB preview” and “Live Test on device” what is happening is the following: the PDF appears normaly on the screen, but just beneath it one can see pieces of text! These texts are extract from the PDF just as if an OCR has been launched!

This doesn’t happened on Android: in that case the screen remains definitively white…

Any ideas ???

Can you post a link to a basic project that demonstrates this?

Here it is:

Could you share a screenshot of what you’re seeing? I just tested the app linked above and am not able to replicate the issue.


Here is the screen shot of Web Preview: the PDF appears normally but at the bottom of it you see lines of text !

btw I’m working on a MacBook Pro with MacOS 14.3.1

Thks for having a look at my problem, I appreciate!

Thank you for sharing. It does seem to be outputting the text of the document as well. I have been able to reproduce this locally only on the Web Preview, not on Thunkable Live or any build/downloaded app on mobile.

We’ll file a bug ticket for this and keep you updated if we are able to get a timeline for fixing this. Appreciate your patience!

Hi Matt

Just want to make sure before I use PDF viewer in my app that it doesn’t have any abnormal behavior, what I am reading is there is a issue with web based app but not on Android or iOS.

Is that correct?

Also searching through forum they were posts using a web component for viewing the PDF is that still valid solution?

I just wanted to get opinion before I spend my time. Thank you in advance.

Correct, only on web.

It depends on the URL but generally yes, if the URL of the file ends in .pdf, this would be a viable work-around.
