PDF is available in multiple versions, each with different features and improvements to adapt to changing technical needs and scenarios. For example, PDF/A is a format specially designed for long-term archiving. It can be used to save documents for long-term use in the future, ensuring that they can still be opened and viewed normally after that. At the same time, PDF/A also supports metadata and text search, which can efficiently retrieve and manage document archives. The following describes how to convert a large number of PDF files into PDF/A versions at once.

When it is necessary to save some important documents for a long time, although the common PDF is convenient, problems such as failure to open or format disorder may occur after a long time. At this time, the PDF/A format can ensure that the documents are still opened normally after long-term storage. The PDF/A format is most commonly used by government departments and hospitals. For example, some policies, regulations or inspection reports and other documents that need to be kept for decades are converted into PDF/A. Even if the future computer system changes, such documents will not be affected, resulting in problems such as unable to open or open garbled codes. At the same time, schools and scientific research institutions also need this format very much, including academic papers and academic graduation papers of tutors, they are all knowledge wealth that needs to be saved for a long time. If they are saved in PDF/A format, after a long time in the future, what others can browse and see will still be the original appearance, and there will be no problems such as font loss and typesetting dislocation. In short, if it is a document that is particularly important, needs long-term preservation or may be used as a basis, it should be considered to be converted into PDF/A format. Although it is similar to ordinary PDF documents in observation, it is actually equivalent to putting a protective cover on the document content and can pass a long time test. How can we batch convert a large number of ordinary PDF documents into PDF/A format?

PDF is the most commonly used file format with strong compatibility in daily office and transmission, but sometimes it needs to be converted into JPG picture format under special circumstances. Pictures directly converted by screenshots or directly are easily blurred and cannot reach the desired clarity. This function allows us to adjust PPI pixels density before PDF document conversion to make PDF documents converted into pictures clearer. PPI is like a picture definition progress bar. The higher the pull-up value, the higher the picture becomes high definition, and the lower the pull-down value, the blurred picture becomes blurred. At the same time, the high-definition picture will increase the picture volume and the blurred picture volume will become smaller. We can rely on this to adjust flexibly. Usually when printing files, PPI is better than 300, and the printed pictures are no different from the original. For files that need to be previewed, PPI is set to about 100, which ensures that all kinds of equipment can see clearly and the volume of files is not too large. There are also PDF files that need to be uploaded to the website. PPI setting 72 is the most appropriate, which ensures readability and greatly improves the loading speed of web pages, converting JPG pictures after setting the pixel density on each page of PDF can obviously reduce the working process, and there is no need to worry about the picture pixels being too low and unclear, or the pixels being too high and too large before compressing the picture. Then we encounter the need to convert every page of a lot of PDF documents into JPG pictures and maintain or improve the clarity of the documents. How should we do it in batches at one time?
