Convert PDF to Word

PDF is considered an ideal file format for document sharing and printing, but it is difficult to edit. If you want to modify the text in a PDF file, you can convert it to Word.

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.

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.

Digitally Sign PDF

A digital signature provides assurances about the validity and authenticity of your PDF documents. Once a PDF document is digitally signed, any changes to the document will invalidate the signature.

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.

Add a Watermark to PDF

Watermarks in PDFs serve many important purposes, such as identifying the document's owner, indicating its status and preventing unauthorized copying and distribution.

Merge and Split PDF

Sometimes, you might need to merge multiple PDF files into one in order to store and review them easier. Likewise, you may also want to split a PDF file into individual files and share them with others separately.

Add Layers to PDF

PDF layer is an interactive feature for PDF documents that allows some part of the content to be made visible or hidden. Layers are used for items such as CAD drawings, layered artwork, maps, and multi-language documents.

Change PDF Page Size

By adjusting the page size of a PDF document, you can easily get a better document appearance or make the page size match the printing paper.
