Resolved Help with resizing jpg for printing

I have no idea on how to go about resizing a jpg to have it printed. I have a couple of pictures my sister emailed to me and I would like to have them printed out. (I have the pictures saved on my computer).
I would like these jpg.'s to be printed out in a 5x7 picture, but given the current resolution of the pictures, I have been told they would print grainy in this form?
I do not own any type of photo editing program (to my knowledge). I use Win7 on my computer and Win10 on my laptop.
Can anyone explain to me how I can accomplish this and have the pictures printed out without the grainy appearance? (I plan on taking them to a photo printing place and not print them from my own printer).
(P.S. I plan on giving these pictures as a gift, so I definitely want them to look somewhat presentable!)

 

You should have Paint on the PC. Try that and see if that works.

 

Hi Vicki, A Google produced this suggestion:
How to Enlarge an Image to Print.

• Double-click your file to open it in preview. ...
• In the menu bar, click on "Tools".
• Select "Adjust Size" in the "Tools" dropdown menu. ...
• Choose "inches" for Width and Height and "pixels/inch" for Resolution. ...
• Uncheck the “Resample Image” checkbox and set your Resolution to 300 pixels/inch.
  
  

 

Thanks for all the suggestions! I did try using the Paint program to resize the image, also found an online website (via google) that would also do this for free. I did get the pictures that I wanted printed, but to be honest, I don't know which one I used to do that! At any rate, mission accomplished!

 

If you look in History Vicki, you should be able to find the Program you used.
Obviously panic over and well done.
