Is it possible to convert .es3 files to .pdf format.
Directly converting e-Szignó Signed Documents to Adobe Portable Document Format (.es3 to .pdf conversion) is most likely only possible using the original Hungarian software, e-Szignó.
We are not aware of any third-party programs or converters capable of an .es3 to .pdf conversion. You could however try software, such as Netlock Mokka or es3.hu, a free e-dossier viewer.
