Users can rely on pdfFiller to offer them a powerful, feature-rich set of document editing tools that sit inside of any modern web browser. The app can edit any PDF file regardless of the program that it was created in. It gives users the freedom to add new images, text or any other content supported by the PDF specification. The editing tools closely resemble those provided by traditional desktop publishing software, which makes it easy for new users to get up and going with it.

Since there's nothing to install, pdfFiller should work with pretty much any modern digital device. Macintosh users as well as those working from PCs running open source operating systems like GNU/Linux and FreeBSD shouldn't have any problems using pdfFiller. All of the files they download from the service adhere to the PDF specifications as well, so they'll be able to open them using native tools. The pdfFiller export function is also certified to work with a variety of mobile operating systems. Dedicated apps for iOS and Android are also available, which helps to make the software that much more portable.

Each time serious edits are made to a document, pdfFiller will automatically save any progress. While some users might find this a bit obsequious, it's actually quite helpful for anyone who might otherwise forget to save changes. It's also helpful for those who find it difficult to undo changes otherwise. Since pdfFiller encourages people to collaborate together on documents, this is also a great way to reduce the risk of inadvertent data loss.

As the name suggests, pdfFiller can help users fill in the blanks in PDF documents that have form fields. Those who want to create PDFs that can then be used by others to enter information can also do so. Since most browsers and document viewers now support data entry, these can then be shared with individuals who don't have a pdfFiller account. Compatibility shouldn't be an issue either, since pdfFiller doesn't make use of any proprietary extensions to the PDF specification.

Standard copy and paste workflows work natively with pdfFiller as long as your web browser supports them. That makes it possible to paste in large amounts of text or graphics with nothing more than a few keystrokes. Some users will prefer to use other, more traditional tools when authoring PDFs and then copy the text over. Others may want to work from a small text editor while they're looking at another document and then paste over their progress once they get a free moment.

Business and academic users alike should appreciate the flexibility and interoperability of pdfFiller, which is designed to be as vendor-neutral as possible.
