Help on chaging PDF models downloaded to differing scale from that aquired please

[Guest]

Can any one please explain a quick and simple way of accurately changing scale of models D/L in PDF format, as, i like to model in 1 to 1oo scale, locos and all vehicles etc etc, say 1/87 to 1/100 or 1/120 to 1/100.

If their is a free to download and use software D/L to be found that will do this automatically, please can some one tell me where it is found, or, if not, how i can as stated above, do alterations but simply and straight forward, to achieve my goals please......

PS......Sorry if this is the wrong area to post, could not see any where else to post this.

Thanks for all help in this matter and best regards to one and all.

As they are PDF files, unless you have some editing software from Adobe, I would thing the only options would be to try to change the output on the printer to scale it or print them as is and use a photocopier that would allow output size to be altered.
