Closing as duplicate of issue #7375; which in itself is a duplicate of issue #5264.

Please take a moment to read through issue #5264 carefully, and you will see that this is caused by Internet Explorer not supporting Blend Modes. This is a limitation of the browser, and not something that we can fix! Given that Blend Modes are not something that can be easily poly-filled, it should come as no surprise that the simple workarounds posted in various issues doesn't really work.

For future reference, please do not open multiple issues for the same PDF file!

Hi @gsampath127 . I'm not sure you are reading the referenced bugs.

  1. Can we recreate the pdf so that it did not break with this issue ?

Use tools to optimize PDF for web and performance. See https://helpx.adobe.com/acrobat/using/optimizing-pdfs-acrobat-pro.html (see Transparency options?)

2.If we can do the above and how it can be achievable ?

See https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#what-types-of-pdf-files-are-slow-in-pdfjs-can-i-optimize-a-pdf-file-to-make-pdfjs-faster

Or you can polyfill blend mode functionality for HTML5 canvas for IE9,10,11. It works for IE Edge.

3.Reason why this pdf is breaking in IE ? (Is something wrong with PDF)

See conversation above -- IE11 and below does not support blending modes and was addressed by IE team in IE Edge.
