Can you tell if PDF has been edited?

[Mark300zx]

Slightly dubious on the costs involved after having a PDF receipt sent to me and wondered if there is an easy way to tell if it has been edited?

Anything in properties/date created/last modified that could give it away from the date of the invoice?

Easy to create a pdf from a previously edited document.

It was sent to me via Whatsapp so I presume this creates problems accessing the data?

[Black_S3]

Not sure what whatsapp or phone storage does to saved times but you could try emailing it to a pc and see it the time stamps give any clues? Could end up being the time stamp from either of the phones though?

Thanks, it just gives the sent date

Ring the source and confirm the amount.
This sounds a bit like tin hat territory.

I have Acrobat Pro, it's as easy to edit a PDF as a word doc! Not sure why PDF's still exist on that basis.

PDF aka Portable Document Format was created by Adobe to allow documents to be shared between disparate systems. The fact they're hard to edit is down to the historic cost of the software not the format.
