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?
1. Use Scenarios
when an enterprise has a large number of PDF product manuals that need to be converted into JPG pictures for printing, but after being converted into JPG, the quality of the pictures should be improved to ensure the quality of the printed results. We can directly increase the PPI pixels density of these PDF files for unified conversion to improve the clarity of the pictures after the conversion, and at the same time avoid separately increasing the pixels and reducing our multi-task process.

3. Operation steps
open 【HeSoft Doc Batch Tool], select [PDF Tool]-[PDF to JPG Picture]].
[Add File] Choose to add PDF files that need to be converted to pictures and improve clarity.
[Import File from Folder] Import all PDF files in the selected folder.
You can view the imported files below.
[Processing Range] Select to process all pages.
[pixel density (PPI)] here to choose the input, you can click to help view the description, the lower the value of the picture more fuzzy, the higher the value of the picture more clear.
After the processing is completed, click the save location to view the successfully converted image file.
