Batch adding electronic stamps to important PDFs such as contracts has become a rigid requirement for anti-counterfeiting and authenticity today. In practice, manually adding stamps wastes a lot of time, and you also need to repeatedly adjust the stamp position on each page. If you only have a few PDFs, you can manage, but when you have dozens or even hundreds of documents that need batch stamping, it becomes very difficult. So, how should we batch stamp PDF documents in such cases? This article shares six practical methods to quickly batch stamp PDFs with one click, making your documents more secure and professional. Let's try them together!
When Do You Need to Stamp an Electronic Seal on Every Page of a PDF?
1. To prevent PDFs from being tampered with, enterprises or institutions can batch-stamp an electronic seal on every page of a document to ensure its professionalism and integrity.
2. When conducting internal audits and submitting approval documents, enterprises can ensure the authority of the files by stamping every page of the PDF to prove the document's authentic source and prevent unauthorized content changes.
3. For PDF files that need long-term preservation, electronic sealing serves for archival certification. The electronic seal can ensure that the document has tamper-proof characteristics and legal validity during storage.
