how to display pdf content full size. iframe doesnt display it as the whole page

        merged_buffer = io.BytesIO()

        pdf_content =
        pdf_base64 = base64.b64encode(pdf_content).decode('utf-8')

Hi @Charlieletscode,

You could try and see if this code works for you. Adjust the height and width as required.

import streamlit as st
import base64

def ViewPDF(wch_fl):
    with open(wch_fl,"rb") as pdf_file:
        base64_pdf = base64.b64encode('utf-8')
        pdf_display = f'<embed src="data:application/pdf;base64,{base64_pdf}" width="1000" height="500" type="application/pdf">' 
        st.markdown(pdf_display, unsafe_allow_html=True)

ViewPDF("./tst.pdf")    # provide file path + full file name


yeah but it still doesn fulfill fullscreen. I believe that there is no such function. answer could be open not restrict to streamlit
