We have a lot of pdf files that need to zoom in.
but when we zoom in, the text didn't clear enough to for users to see.

Normal Adobe Reader:
normalpdf

Pdf.js :
blur

Orignial File:
test.pdf

Is there any way to improve this situation ?

Is there any update on this? We have the same issue but with zoom level 100% where the text becomes blurry in pdfjs, but not in other pdf viewers. Actually it's more than just the text, lines become blurry as well.

These are documents that need to be measured, so it's quite hard when you can't see the end of a line because the object next to it is so blurry.

I can't share the source because of gdpr but I attached 2 images to show the difference. The very blurred one is pdfjs.
