How to convert massively from pdf to pdf/a

when processing several pdf I get this exception “Exception in thread “main” java.lang.OutOfMemoryError: Java heap space”
//this is the code I am using

for (String archivo : carpeta.list()) {
Document pdfDocument = new Document(_dir + “/” + archivo);
// convertir a pdf/a
pdfDocument.convert(_dir + “/log.xml”, PdfFormat.PDF_A_1A,ConvertErrorAction.Delete);
nombrearchivo = pdfDocument.getFileName();“src/out-pdf/” + nombrearchivo);


Can you please share your sample PDF file for our references so that we can test the scenario in our environment and address it accordingly.

I’m sorry, but my pdf is confidential, is there another way to address the problem?

Thank you very much for your attention, after investigating a bit more about it I was able to solve the problem, simply adding an argument to the class to increase jvm memory --> -Xms8g
