pdf b4转a4(教你实现PDF文件大小的转换)

if you have ever had the need to reduce a large-format pdf from legal or tabloid size (8.5 x 14 in or 11 x 17 in), to the more common a4 page size (8.27 x 11.7 in), then you already know the feeling of dread that may accompany that task. fitting an 8.5 x 14 in page onto an 8.27 x 11.7 in page can take the patience of a saint and a willingness to deal with some minor annoyance.
converting these large pdfs to more traditional size pages can prove to be quite a hassle. copying, pasting, and resizing down pages of denser content is definitely a chore (not to mention time consuming).
fortunately, there is a better way. many pdf readers, such as adobe acrobat, feature built-in tools to quickly and conveniently convert from larger formats to the a4 page size. without having to strain your brain on a long method of awkward copy-oscaise motions, you will be outputting those professional documents in no time.
to quickly and easily convert pdfs from 8.5 x 14 or 11 x 17 formats to a4 (or in reverse if desired), simply:
1.open the desired pdf file in adobe acrobat
2.go to "file"/"print settings..."
3.in the print setup dialog box, select the paper size appropriately.
4.close the dialog box, select the "page scaling" drop-down menu and then select "fit to page".
5.the page should now be properly sized and formatted. simply go back to the "file" menu and select "save"
so as you can see, there is no reason to cringe any longer at the thought of oversized format scanning and converting your documents to the a4 paper size. adobe acrobat can easily do all the heavy lifting to ensure you get 1:1 results highlighted in crisp and clean details.

pdf转换a4

失败
我们无法将pdf文件转换为a4尺寸，因为pdf数据是用2d参数来描述的，而a4尺寸是3d的，因此无法将paf文件转换为a4尺寸。建议您使用文本或图片转换器将pdf文件转换为另一种格式，然后再将其转换回a4尺寸。

pdfb4变a4

不可能将pdf文件从a4页面大小变更为b4页面大小，因为pdf文件大小已固定，一般其比列表示1:1.41。建议您打开pdf 使用文本编辑工具将pdf缩减至b4页面大小即可。
