A word processor is software that lets you write, edit, and format text documents on your computer or phone

A word processor is a program designed to help you create and change written documents. You open it, type text, and save what you've written as a file. Unlike typing in an email or a text message, a word processor gives you tools to make your document look professional — you can change font sizes, add bold or italic text, adjust margins, insert images, and organize content with headings and lists.

The most common word processor is Microsoft Word, which comes with Microsoft Office. Other options include Google Docs (free, works in your web browser), Apple Pages (for Mac and iPad users), and LibreOffice Writer (free and open-source). All of them do the same basic job: they turn your typing into a formatted document you can save, print, or share.

Word processors are different from plain text editors (like Notepad on Windows) because they store formatting information along with your words. When you make text bold in Word and save the file, that boldness stays there when you open it again. A plain text editor strips all formatting away — it's just the words, nothing else.

Key Takeaways

  • A word processor is software that lets you write, format, and save text documents with features like bold, italics, font changes, and page layout control.
  • Microsoft Word is the most widely used word processor, but free alternatives like Google Docs and LibreOffice Writer do the same job.
  • Word processors save formatting (bold, colors, fonts) along with your text, unlike plain text editors which save only the words.
  • You can use a word processor to create letters, resumes, reports, essays, and any other document that needs to look polished and organized.

The difference between a word processor and other writing tools

Email programs like Gmail or Outlook let you type and send messages, but they're not word processors — they're built for short communication, not long documents. Email has basic formatting buttons (bold, italic, underline), but you can't control page margins, set up headers and footers, or organize a multi-page document the way a word processor lets you.

Google Docs sits in the middle. It's a word processor that lives in your web browser instead of on your computer. You don't install it; you just go to Google.com and log in. It works like Microsoft Word in many ways — you can format text, insert images, and collaborate with others in real time — but it's simpler and has fewer advanced features.

Spreadsheet programs like Excel or Google Sheets are designed for numbers and data in rows and columns, not for writing paragraphs. A presentation program like PowerPoint is built for slides and talking points, not for documents you'll print or read as a whole. A word processor is specifically for text-based documents.

What you can do with a word processor

The core tasks are writing and editing. You type your content, then you can go back and change words, move paragraphs around, delete sections, or rewrite anything without starting over. Most word processors show you a blinking cursor where your next keystroke will land, and they keep track of every change if you want them to.

Formatting is where word processors shine. You can change the font (the style of letters), make text larger or smaller, add bold or italic emphasis, change text color, and adjust line spacing. You can create bulleted or numbered lists, indent paragraphs, and set up tabs so columns of text line up neatly. You can add page breaks so a new section starts on a fresh page.

You can insert images, tables, and shapes into your document. You can add headers and footers (text that repeats at the top or bottom of every page, like a page number or your name). You can create a table of contents automatically if you've used heading styles. Most word processors also have a spell-check tool that flags misspelled words as you type.

How to save and share documents from a word processor

When you finish writing, you save the document by pressing Ctrl+S (on Windows) or Command+S (on Mac), or by clicking File and then Save. The program asks you where to put the file and what to name it. You choose a folder on your computer (like Documents or Desktop) and type a name like "Resume" or "Letter to Landlord."

Each word processor saves files in its own format. Microsoft Word saves as .docx files. Google Docs saves as .gdoc files (though you can read it as .docx to use in Word). LibreOffice saves as .odt files. These different formats exist because each program stores formatting information slightly differently. Most modern programs can open files from other programs, but sometimes formatting gets jumbled in the conversion.

To share a document, you can email the file as an attachment, upload it to cloud storage like Google Drive or OneDrive, or use the sharing features built into the program. Google Docs makes sharing especially straightforward — you can give someone a link and they can view or edit the document without downloading anything.

Why you might choose one word processor over another

Microsoft Word is the industry standard. Most workplaces use it, most schools accept Word documents, and it has the most features of any word processor. The downside is that it costs money — you either buy it once or pay a monthly subscription for Microsoft 365. If you already use other Microsoft programs like Excel or Outlook, Word integrates smoothly with them.

Google Docs is free and works on any device with a web browser — your computer, tablet, or phone. You don't install anything; you just log in. It automatically saves your work as you type, so you'll never lose a document to a computer crash. The trade-off is that it has fewer advanced features than Word, and you need an internet connection to use it (though you can work offline and sync when you reconnect).

Apple Pages is free if you own a Mac, iPad, or iPhone. It's simpler than Word but more powerful than Google Docs, and it works seamlessly across Apple devices. LibreOffice Writer is free and works on Windows, Mac, and Linux, making it a good choice if you want a full-featured word processor without paying. The downside is that it's less common, so fewer people know how to help if you get stuck.

Common tasks you'll do in a word processor

Writing a resume or cover letter is one of the most common uses. You open a blank document, type your information, format it so it looks clean and organized, and save it as a PDF or Word file to send to employers. A word processor makes it straightforward to adjust spacing, highlight your name at the top, and organize your work history into sections.

Creating a letter — to a landlord, a business, a government office — is another everyday task. You can set up the date, recipient address, and signature line in the right places. You can save a template (a blank letter with the structure already in place) so you don't have to rebuild it every time.

Writing longer documents like essays, reports, or proposals is where word processors really help. You can organize your thoughts into sections with headings, add page numbers, create a table of contents, and keep everything formatted consistently. If you need to make changes, you can do it without retyping the whole thing.

Frequently Asked Questions

Do I need to pay for a word processor?

No. Google Docs is free and works in any web browser. LibreOffice Writer is free and works on Windows, Mac, and Linux. Microsoft Word costs money, but if you only need basic word processing, the free options work just as well.

Can I open a Word document in Google Docs?

Yes. You can upload a .docx file to Google Docs, and it will convert it so you can edit it. You can also read a Google Doc as a Word file (.docx) to send to someone who uses Microsoft Word. Formatting usually stays intact, though complex layouts sometimes shift slightly.

What's the difference between saving and exporting?

Saving stores your document in the program's native format (Word saves as .docx, Google Docs as .gdoc). Exporting converts your document to a different format, like PDF or plain text. Exporting is useful when you need to send a document to someone using different software or when you want to lock the formatting so it can't be changed.

Can I use a word processor on my phone?

Yes. Google Docs, Microsoft Word, and Apple Pages all have phone apps. They work the same way as the computer versions but with a smaller screen. Google Docs and Word are free on phones; Pages is free if you own an iPhone or iPad.

What happens if I close a document without saving?

Most word processors will ask you "Do you want to save changes?" before closing. If you click No, your changes disappear and the document stays as it was the last time you saved it. Google Docs saves automatically, so you don't have to worry about losing work.
