L and I letters thickened

I had a free trial with Adobe, and from that time, even after I cancelled my trial, the letter l and capital i of my PDF files appeared thickened. I uninstalled Adobe and installed it again, created a new account, started a new trial, etc., but nothing has worked. When I download new documents, it still happens. I uploaded a small picture to exemplify it. Any suggestions, please? Thanks!

Is it with all PDFs or just one/a few?

Hi @yolanda_2849,

Thank you for reaching out and sorry for the troubled experience.

This issue you’re experiencing — where capital “I” and lowercase “l” appear bold after editing a PDF — is often due to font substitution or font rendering issues in Adobe Acrobat. Here’s how you can troubleshoot and fix it:

Sometimes Acrobat substitutes fonts during editing if the original font isn’t embedded or available on your system.

How to check:

Open the PDF in Adobe Acrobat Pro.
Go to File > Properties > Fonts tab.
Look for the font used in the document. If you see “substituted” next to it or if the font is missing from your system, that’s likely the cause.

Solution:

Try replacing the font with a similar one you have installed.
Or embed the correct font using a PDF editor (if you have access to the original font): https://adobe.ly/3Esf9Hw

Let us know how it works.

Hi Tariq! Thanks for your answer. It actually happens with new pdfs that I have never modified too even when I log out 😞
