It has the effect of avoiding limitation in the email transmission volume and optimizing the volume unit for transmission. In addition, in the process of creating one PDF document by automatically merging the files, a user in the receiving side can edit and set the format of the file index, bookmarks, and the like. Therefore, there is an effect of preventing file errors and using a large-volume PDF file as it is in its original form.

Description

A device and method for converting PDF documents in units of capacity {APPARATUS AND METHOD FOR CONVERTING FROM/TO PDF DOCUMENTS IN CAPACITY UNITS}

The present invention relates to a PDF document conversion apparatus and method, and more particularly, to a PDF document conversion apparatus and method in units of capacity.

Documents such as MS Word or Korean (HWP) can be converted into PDF documents and used.

However, PDF documents can be usefully used to deliver non-editable content to others. However, if the size of a PDF document is large, there are many cases in which e-mail transmission is not possible due to the transmission capacity limitation.

However, the PDF program does not provide a function for converting by dividing into a certain capacity unit. Accordingly, in many cases, a word document is divided into an appropriate size unit and output or a part of a PDF document page is deleted to meet the transmission capacity. However, there is also no function to predict capacity.

In addition, in the case of dividing and converting a file, the recipient is inconvenient to merge it again, and when merging, an error occurs even after merging due to an error such as bookmark information or link information.

In addition, there is a problem in that the divided PDF files are merged as they are, even when the configuration or shape of the bookmark is different.
