Compress PDF
Compressing PDFs can reduce their size by 10 to 100 times, thus saving you a lot of storage space and making PDF documents easier to transfer over the Internet.
Extract Text and Images
When you just need to get the information in a PDF document regardless of its format and structure, you can simply extract the text and images from the document.
Create a Form
Form fields make it easier to collect information. Users can enter information by choosing an item from a drop-down list, inserting text in a combo box, or checking a check box.
PDF Encryption
PDF encryption is a crucial task when it comes to sharing confidential documents on the Internet. Using Spire.PDF, you can set a password to restrict access to your PDF file, or set permissions to define what actions users can perform on the document.
Merge and Split PDF
