Before downloading, you must identify the correct URLs. Jsoup's CSS selectors make it easy to find all links ( tags) whose href attribute ends with .pdf .

For large files, loading the entire byte[] into memory can cause an OutOfMemoryError . In these cases, it is safer to use a BufferedInputStream to stream the data directly to your disk. Before downloading, you must identify the correct URLs
Jsoup is not designed to parse binary data like PDFs, but its Connection interface can still fetch the raw bytes of a file. To do this, you must set .ignoreContentType(true) because Jsoup expects HTML by default and will otherwise throw an error for a application/pdf MIME type. Method: Using Jsoup's execute() This method is straightforward for smaller files. Key Considerations For large files, loading the entire
