Adobe Acrobat on Mac OS: Blurry Font/Document Following Sanitization

[Virgilios5DE5]

Hello,

I have the latest Adobe Acrobat (subscription) on my MacBook, most recent OS.

Everytime I edit a PDF, and then opt to Sanitize and Save, the entire document is blurry, and all fonts are blurry. 

This is evident on all PDFs, whenever they are edited and new things is written etc.

How can I fix this, surely there must be a way?

Is the document a scan?

Can you post a test document with before/after and the exact steps you are taking?

What is the exact version of Acrobat and the exact version of your macOS. Please note: the “latest” may be true, or may not be true, we do not have a possibility to check that. And at least with the next version, the “latest” won't be true any more.

Hello,

Thank you for taking your time to reply. The exact version is :

Architecture: arm64

Processor: Apple M2

Build: 23.8.20470.0

AGM: 7.1.3

CoolType: 9.0.2

JP2K: 4.0.1.53159

and my Mac OS is 14.3 (23D56).

I basically uploaded a PDF file, not a scan or image. I went to the Edit feature and changed text, it had already recognised the text. I then proceeded to make the changes I wanted and went to Sanitize, let it do it's job and once it saved the entire PDF from images on PDF as well as the text are fully blurry.

First, use the "Selectively remove" option.

Then pay attention to what's checked, because there's an option that turns the whole page into an image (but I can't remember which one), which has happened to me a few times.
You may need to run several tests to find it, so don't overwrite your document.

Nothing shows on my end that it could convert it to an image

I believe the sanitize tool will convert the entire pdf to an image and will also reduce the resolution of existing images. May I ask why you need to sanitize your pdf? you can remove metadata (and many other things) using the save as optimized pdf tool.

It doesn't say it, but sometimes it does anyway.
