PDF is one of the most commonly used file formats in daily office work and file transfer due to its strong compatibility. However, under certain special circumstances, it may be necessary to convert it into the JPG image format. Directly taking screenshots or converting directly to images often results in blurry images that fail to meet our expected clarity. This feature allows us to adjust the PPI pixel density before converting the PDF document, making the PDF pages converted to images much clearer. PPI is like an image clarity slider — dragging it upward increases the value and makes the image high-definition, while dragging it downward lowers the value and makes the image blurry. At the same time, high-definition images result in larger file sizes, while blurry images have smaller file sizes, allowing us to adjust flexibly according to this. Typically, when printing files, it is best to set PPI to 300 or above, so the printed images show almost no difference from the original. For files that need to be distributed for preview, setting PPI to around 100 is sufficient, ensuring clear visibility on various devices while keeping the file size manageable. For PDF files that need to be uploaded to a website, setting PPI to 72 is most suitable, ensuring readability while significantly improving the web page loading speed. Setting the pixel density for each page of the PDF and then converting to JPG images can noticeably streamline the workflow, eliminating worries about images being too low in pixel density and unclear, or too high in pixel density with large file sizes requiring further compression. So, when we encounter the need to convert every page of numerous PDF documents into JPG images while maintaining or improving the clarity of the files, how can we complete this in a single batch operation?
1. Use Cases
When a company has a large number of PDF product manuals that need to be converted into JPG images for printing, but the image quality needs to be improved after conversion to ensure the quality of the printed results, we can directly increase the PPI pixel density of these PDF files for unified conversion. This improves the clarity of the images after conversion, while avoiding the need to separately enhance pixels, thereby reducing the number of steps in our workflow.
