Technical Field

The present disclosure relates to, but not limited to, office application technologies, and more particularly, to a method, an apparatus, a computer storage medium, and a terminal for compression processing.

Background

When exporting a Portable Document Format (PDF) document, the application that generates the PDF document inserts an image, an embedded font, and some private data (data that can be reconverted into a document of another format or data that can be subjected to other arithmetic processing) into the generated PDF document.

Before uploading PDF documents on websites such as forums or blogs, a user generally compresses the PDF documents according to the parameter requirements of the websites on the document formats and sizes, and if the size of the compressed PDF documents does not meet the website requirements, the user re-compresses the PDF documents until the parameter requirements of the websites are met, and normal uploading of the PDF documents can not be realized.

To sum up, after the PDF document is compressed, when the parameter requirements of the size of the website cannot be met, the user needs to compress the PDF document again until the parameter requirements are met, and the PDF document can be uploaded, so that the use experience and the working efficiency of the user are influenced.
