Why PDFs Won't Open and What to Do About It

Are you downloading an important file, only to see an error message instead of text? Does the document freeze or display incorrectly? These are typical signs of a damaged PDF. The reasons can vary:

1. File-saving interruption. For example, if the process was interrupted by closing the program.
2. Damage during transfer — if the document was uploaded through an unreliable connection.
3. Virus impact. It's rare but possible.
4. Format incompatibility. Older software versions might not always open new PDFs.

No matter if you’re working on a computer, iPhone, or Android phone — you can fix the PDF right in your browser without installing third-party programs.
