How to edit PDF files?

BANGALORE, INDIA: Coded in Java, PDF Studio 6.5 is platform independent and can run on Windows, Macintosh and Linux.

The tool lets you scan images (using any TWAIN compliant scanner) and place them straight into an existing or a new PDF document. TWAIN is the standard software interface to any scanner hardware.

Most scanners come with TWAIN drivers that are installed automatically as part of scanner installation. The other utility is that the software lets you edit PDFs and insert texts, watermarks, images, sounds, objects, etc. It also provides advanced editing features such as cross-out, underline, highlight, etc.

What makes the tool even more interesting is its ability to import files directly from URLs, Google Docs, Adobe.com and SharePoint. It also has the ability to convert PDFs to image formats (.jpeg) and documents and spreadsheets to PDFs. Making PDFs secured by adding digital signature authentication and password-protection is another advantage. Overall, a pretty useful tool that further allures you with a free price tag.
