How to Convert A PDF file to Audio Format

Nowadays, multitasking—doing several tasks at once—has become routine. Especially when we are driving on the road or engaged in other activities like cooking, exercising, or just unwinding, many individuals would rather listen to content than read it. Converting a PDF file to an audio file is a Text-To-Speech function that can make information consumption easier, more pleasurable, and more entertaining since, although books can be heavy at times and difficult to finish, audio files save time.

Afterward, turning a PDF to audio can improve accessibility by enabling those who are blind or visually handicapped to "read" them. Any PDF may be converted to an audiobook, which is also practical for people who would rather listen than read.

In this guide, I'll walk you through various ways to convert a PDF document to an audio format.
