Is it wrong to change the name of the university on a recommendation letter One of my professors gave me a recommendation letter for my master's degree application however I just noticed that she wrote the specific program that I'm applying to from a different university that I want to apply as well. Is it alright to just change that data? She send it on a pdf file, and I could easily change it to word and change it, but I don't know how acceptable that is. I'm afraid that the new program I want to apply will think is a fake letter or something like that. What should I do? Is 1.45 am and I need to finish the application ASAP.
You cannot do this. 

Your professor recommended you for University A; changing their recommendation to University B is fraud. I realize that they are probably also willing to recommend you for University B (they may even have promised to write a letter for University B), so I know it seems like you're just saving everyone some  time. 
But, the professor still hasn't authorized you to do this. I for one would be angry if I found out that anyone submitted a letter with my name on it without my explicit permission (and, for an undergraduate student, I would indeed want to glance at the updated letter before approving it). 

The other concern is that University B could somehow find out about this and assume the worst (that you falsified the letter). They could reject you without even bothering to ask for clarification. 

So, three options:


Ask the professor to change it
Ask the professor if you can change it (this addresses the first concern only)
Submit it as-is -- as noted in the comments, programs will not generally be too concerned about this mistake, particularly if Universities A's competitiveness >= University B's competitiveness.
