WYSIWYG stands for What You See Is What You Get. It is an editor that shows your content formatted the way it will look once published, so you work with bold text, headings and images directly instead of writing code and guessing how it renders.
The classic comparison is Microsoft Word versus writing a letter in plain code. In Word you make a word bold by clicking a button and it instantly looks bold. A WYSIWYG editor brings that same comfort to the web: the WordPress editor is a good example, and most content management systems ship with one so non-technical staff can update pages without help. The line between a WYSIWYG box and a full page builder blurs in tools like Elementor, but the difference is real. A page builder moves whole sections around, while a WYSIWYG editor mostly cares about the words inside one.
There is a catch worth knowing. What you see is what you get, but only roughly. The editor renders on one screen size, while real visitors arrive on phones, tablets and wide monitors, so spacing and line breaks can shift. WYSIWYG editors can also produce cluttered HTML in the background, which is why developers often pair them with cleaner rich text handling under the hood. Picture a marketing manager who needs to swap last month’s offer for a new one. With a clean WYSIWYG field she edits the headline, drops in a fresh image, hits save, and the page is live in under a minute. No ticket, no developer, no waiting.
At TopDevs we set up WYSIWYG editing so clients can confidently change their own copy and images, while keeping the underlying markup tidy enough that performance and SEO never suffer for the convenience.
