I want to view a PDF-file on an HTML page by using Base64 and an iFrame. When I upload a PDF-file with less than 1kb it works, anything above that number does not. Test view by object data doesn’t work either.

Concern to big pdf file size:

1. On Server site:
   Reduce the file size by using any compression method with output is stream string. (Be better to cache the compressed file).

2. On Client site:
   Uncompress the compressed string (ie. using pako js) to pdf format and display it in the iframe.

  • You means it needs to be decoded into regular pdf format? – OO7 Dec 28 '19 at 22:16
  • Mention to big pdf size you can also use any slide show inside the iframe, so the file could be split into several string stream over several client request. – OO7 Dec 28 '19 at 22:23
