Well, your attached PDF indeed contains a very small image, I can NOT zoom in further in Chrome while viewing your PDF directly?

Hello Cem

 When you zoom the image in chrome you can notice that the image is clear. But this is not the case with document viewer. It is blur.

The screenshot above is indeed max zoom of your PDF in Chrome, does it look clear/readable to you?

So the problem is your PDF, while generating it, you used a very small image so viewers can't do anything about it.

Create a PDF with high-res image.

Hello Cem

  I am able to read the text on the image via chrome. But this is not the case via the document viewer. It is blurred out. The reason I am requesting this is because in our application we cannot control on what kind of images our clients upload, hence the request.

You sent me DummyImage.pdf as attachment in first post and I put a screenshot at maximum zoom in Chrome PDF Viewer.

So you say you can read the small text in this 360x240 image?

> we cannot control on what kind of images our clients upload 

Maybe you clients should not upload dummy PDFs. This PDF is useless, they created a PDF from thumbnails not original images.

Well, I now see the problem:

So there seems to be a strange problem with this PDF, Even Chrome PDF Viewer "zoom in" button does not work, only "Fit to width" button enlarges the image.

Yes correct, In the Document viewer though, if you try to zoom in (plus button) it blurs out. It not readable as the Chrome PDF viewer. Is that a limitation?
