The PDF format is a fixed-page format that is very popular among users and widely supported by various applications, because a PDF document looks the same on any device. PDF and XPS formats are very similar in their purposes and basic concepts, while internally they are quite different. For that reason, editing PDF is an important feature of GroupDocs.Editor.

Various document viewing or publishing applications allow users to open (Adobe Acrobat, XPS Viewer), and sometimes edit (Adobe InDesign) documents of specific formats. These applications typically produce so-called “fixed-page” format documents. Such a document format describes precisely where a document’s content is placed on every page. Internally, the PDF format contains a description of every page, as well as drawing instructions, specifying the layout of the content on the page. This is similar to image formats, describing where the content is shown either in raster or vector form.

In order to make a PDF editable, the GroupDocs.Editor uses advanced and complex algorithms, optical recognition, machine learning, and so on, so on the result users are able to edit all content of the document like an ordinary WordProcessing or textual document. This works whenever or not the PDF documents have textual layer, internal semantic structure (as described in PDF/A-1a, PDF/A-2a, and PDF/UA-1 formats), support search/find operations and so on. Application supports all common document structures like paragraphs, images, tables, lists, headers and footers, footnotes, page numbers, and many more.

Portable Document

Portable Document Format (PDF) captures a complete document’s layout, fonts, images, and interactive elements in a fixed structure viewable consistently across any device or platform. Developed by Adobe, PDF is the standard for sharing, printing, and archiving documents—from contracts and reports to eBooks and forms—preserving original formatting and enabling security features like encryption and digital signatures.

FAQ

Questions & Answers

How can I edit a PDF file using PDF Editor?

First of all, you need to select and add this file for editing by two ways: drag and drop your file to the white area with the label ”Click or drop your file here” or click on this area and then select the desired file using file explorer. Once a file is added, the green progress bar will begin to grow, and when completed, the PDF Editor will be opened with file content inside it.
The Editor was opened after file uploading, but there is a “Please wait, while document is loading” message and no any document content. Will it appear and how long does it take?

The document loading time depends on three factors: document size, the complexity of document content and aspects of the document format. For example, plain text files (TXT) are much easier to open and display than XLS spreadsheets, and it may be faster to open an eBook with a huge 1000 page novel inside rather than a complex 10-slide PPTX presentation with tons of animations, comments and images.
How can I edit the content of a document when it is opened in the Editor?

In short: like in any other WYSIWYG-editor. There is a toolbar with three groups of tools: File, Format, and Insert. First group contains buttons for saving and downloading the document, second is responsible for formatting existing content, while third — for inserting the new entities inside content like images, tables, lists and so on. There also are two emerging groups of buttons on the toolbar — Table and List. They appear when you point at a table or a list respectively and contain tools for working with them like adding or removing table rows and columns, list indentation and so on.
Does PDF Editor require an internet connection when a document is loaded and opened?

Yes, the PDF Editor is a client-server tool where WYSIWYG-editor is only a facade for a server-based software. If an internet connection is lost during document editing, you will not be able to save and download the edited document.
What about privacy, is it safe to use the PDF Editor?

Yes, it is. Editor usage scenario implies that you select and open a document, edit it and then save and download the edited version, and that’s all. The unique URL is generated after you’ve opened the file, but this URL is known only for you and no one else. Finally, the uploaded file will be automatically deleted from our servers after 24 hours after uploading and this URL will become inactive.
Can I edit a document on Linux, Mac OS or Android?

It can be anything that has a modern browser and an internet, no matter what device it is, which operating system is there, and what the browser is. PC or smartphone, Windows or Mac OS, Android or iOS, Chrome or Firefox, — all of them are supported.
