Quick question... Why do designers send clients a PDF of the logo?

My graphic designer sent me a PDF of the logo she designed for me.

I don't know what I can do with the PDF. Am I supposed to be able to open it and use it?

I ask because I need a different size PNG logo than she sent me. Can I somehow use the PDF to resize it myself?

Thanks!

 

It depends on the requirements of the client if you send them in pdf format then can use it directly in the any document or can printe them with the text info in it

 

Is the PDF the final, paid for copy? If so, ask her to save it in a format you can use.

Typically, designers will send a PDF of a proof so you can request changes. The designer will want payment before sending a useable web format.

 

Good answers - thanks @ Ray Baron and techwonder.

Yes, I paid for the job months ago. She sent me a few different JPEG sizes of the logo, plus the PDF.

Problem is, I now need different sized JPEGs than she gave me.

And I wondered why she sent me the PDF version of the logo. Doesn't seem like it's something I can alter and use.

 

you can open the PDF with adobe illustator
it's vector file

 

You might be able to resize the JPEG using Irfanview. Also, Irfanview can convert PDFs to other formats.

I always ask for the PSD (Photoshop) or AI (Illustrator) file once work is complete. Makes it easier to make changes when needed in the future.

 

Thanks @ vtoy_parker and Ray Baron. I'll definitely try both of your suggestions!

 

Ask her for every type of file wither it be the pdf, the raw AI file, a png, etc. Don't hesitate to ask for what you really need, she is working for you.

 

so that you can't make any change in document.

 

pdf file is a big help when you are printing a logo or bigger files like books, magazine and etc.
instead of using ai or cdr or whatever, pdf is more lighter than those mentioned. and if it's light, the printing is fast..not much loading happening when it's printing.. that would be all. thank you. haha!

 

I would recommend that you install GIMP, and use this for resizing your current images (wont handle pdf though). Gimp is a little overwhealming at first glance, however, theres video tutorials on youtube, and any question just ask here.
Using gimp, to adjust the sizes of your current images, is really easy, the hard part is knowing which buttons do what, once you know the buttons its easy. Ideally though, if she can resend you the psd file (gimp can handle this) then you will have greater control and flexibility in what you do.
