Hi
We have a customer using SharePoint 2013 and Office Web Application to provide PDF and WORD documents to partners. Now we ran into the problem, that all PDF are rendered in such a poor quality, that it is hard to read the PDF document, because it is so blured. DOCX documents are also compressed, but readable. If the user downloads the PDF file, the Quality of the PDF is good.

That is how it looks in Office web application:

This is the same file downloaded and opened with the pdf client:

Is there any solution for this problem? Does Microsoft planned any update on this?

Thanks

Michael

Hi Michael,

Are you using a monitor with high resolution?

Per the following information, if you are using a monitor with high resolution, the pdf rendered by OWA from browser will look blurry, as a workaround you can open PDF file using PDF client software currently.

"The Word Viewer in the WACs converts documents (including PDFs) to PNG images at 96 DPI which is likely why the users are seeing blurry text if they are viewing documents on a high DPI device/monitor (>200 DPI)."

Thanks

Hi Daniel,

I have the same problem. So is any solution to solve blurry text problem? Is any way to change conversion to 200?

Hi Daniel,

My Monitor is set to 96 DPI. Honestly, I think it is a problem on OWA side.

It only happens with PDF files. If I upload a word (DOCX) document with images, the quality of rendering is ok.

Thanks

Hi Daniel,

I have to correct me. The blure effect also happens in word documents (docx). Even much more worse:

WORD at 150% zoom:

OWA at 150% zoom:

Update:

I opened a Microsoft call according the above problem. The Microsoft Support accept the issue and past
it to the development team. Unfortunatly (as usual), the are not able to tell if the can fix the problem and when. There is also no work a round.

Yeah we're having the same issue.  The problem is, that the customer needs IRM enabled libraries and only wants the staff members to view in the browser.  Is there a setting on the WOPI servers that can increase the DPI for rendering?

We've also noticed that the user cannot click on Hyperlinks either in WOPI documents.

Jase.
