How to download
Open a book page, find “Download for free”, and choose EPUB or Plain Text. PDF is not a standard option on the example page.
Before listening
Check the contents and introductory material before narration. In our TXT test, the file included source information, a contents list and the book text; we selected only two opening paragraphs.

The example is listed as public domain in the USA. If you are in the UK or Europe, check the status of the specific work and edition where you live.
Alice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do: once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, “and what is the use of a book,” thought Alice “without pictures or conversations?”
So she was considering in her own mind (as well as she could, for the hot day made her feel very sleepy and stupid), whether the pleasure of making a daisy-chain would be worth the trouble of getting up and picking the daisies, when suddenly a White Rabbit with pink eyes ran close by her.

Before listening
Our EPUB test detected 18 sections, including the imprint, illustrations list and colophon. We selected two body paragraphs from “A Mad Tea-Party” and excluded its heading.

There was a table set out under a tree in front of the house, and the March Hare and the Hatter were having tea at it: a Dormouse was sitting between them, fast asleep, and the other two were using it as a cushion, resting their elbows on it, and talking over its head. “Very uncomfortable for the Dormouse,” thought Alice; “only, as it’s asleep, I suppose it doesn’t mind.” The table was a large one, but the three were all crowded together at one corner of it: “No room! No room!” they cried out when they saw Alice coming. “There’s plenty of room!” said Alice indignantly, and she sat down in a large armchair at one end of the table.
What we actually tested
Input
Standard Ebooks EPUB · 18 detected sections.
Preparation
Selected the first two paragraphs of chapter VII, excluding the chapter heading. The EPUB parser returns continuous text; reviewed punctuation before narration.
Import notes
The chapter title was preserved, but the import also included the imprint, colophon and uncopyright notice. EPUB still needs a chapter review.

A source of free digital textbooks for studying science, social science and other subjects. Start with a prose-heavy section when preparing material for listening.
How to download
Open a textbook’s details page and find its PDF download. The case below links directly to the older Psychology PDF we tested; it is a 2017 revision, distinct from today’s Psychology 2e.
Before listening
Our first-edition Psychology PDF test detected 19 sections across 754 pages. We selected prose from section 1.1 and left out the nearby figure caption and outline.
Rights & region
The tested 2017 PDF states CC BY 4.0. Current Psychology 2e uses CC BY-NC-SA 4.0. Check the exact file and edition’s license, retain attribution and review adaptation terms before sharing audio.
Psyche comes to represent the human soul’s triumph over the misfortunes of life in the pursuit of true happiness (Bulfinch, 1855); in fact, the Greek word psyche means soul, and it is often represented as a butterfly. The word psychology was coined at a time when the concepts of soul and mind were not as clearly distinguished (Green, 2001). The root ology denotes scientific study of, and psychology refers to the scientific study of the mind. Since science studies only observable phenomena and the mind is not directly observable, we expand this definition to the scientific study of mind and behavior.
Selected the paragraph explaining the word “psychology” in section 1.1 (printed page 6). Excluded the nearby image caption, outline and page heading. Joined whitespace; retained the original citations.
Import notes
PDF outline entries identified the chapter. Selecting a paragraph within it avoided surrounding figure credits and learning objectives.
CC BY 4.0 ↗. This license is printed on page 4 of the tested 2017 PDF. It does not describe Psychology 2e: its current PDF has a CC BY-NC-SA 4.0 license.

In our increasingly technological and internationalized workplaces, communications skills are among the most sought-after competencies employers require of job candidates. Every job posting you see will almost certainly ask for candidates with excellent communications skills and the ability to work effectively in teams. The ability to communicate clearly and effectively in written, verbal, visual, and interpersonal contexts is vital for success and advancement in the workplace. No matter how brilliant or innovative an idea may be, if it is not communicated clearly and promoted effectively to the right audience, it will not become a reality.
What we actually tested
Input
BCcampus-hosted EPUB · 59 detected sections.
Preparation
Selected the first four sentences of the introduction. Excluded the title, author line, project diagram and image description.
Import notes
The EPUB separated the introduction from the contents and subject chapters. The selected prose reads naturally; later diagrams and lists still need review.
Suzan Last, Technical Writing Essentials, University of Victoria, 2019. Audio adaptation by DocsToAudio.

Open Textbook LibraryBest forCourse & subject discoveryFormatsPDF · Title-dependent formatsAccessCatalog is free; downloads vary⌄
Open Textbook Library
A discovery catalog supported by the Open Education Network. Subject categories, faculty reviews and license details help you compare textbooks before following a publisher or author’s download link.
How to download
Open a book record and look under “Formats Available”. The example’s PDF link goes to the author’s Google Drive. Our case also links the version 1.4 repository mirror used for testing.
Before listening
The tested PDF was grouped into 17 sections of up to 15 pages rather than named chapters. We located the preface inside the first group and selected four opening sentences.
Rights & region
Each book has its own license. The tested logic textbook is CC BY 4.0. The library’s free catalog does not grant a single license for every listed title.
This is an introductory textbook in logic and critical thinking. The goal of the textbook is to provide the reader with a set of tools and skills that will enable them to identify and evaluate arguments. The book is intended for an introductory course that covers both formal and informal logic. As such, it is not a formal logic textbook, but is closer to what one would find marketed as a “critical thinking textbook.”
What we actually tested
Input
Version 1.4 PDF · 242 pages · 17 detected sections. The tested file came from the eCampusOntario repository mirror.
Preparation
Selected the first four sentences of the preface (printed page i). Removed the page header and number; kept the author’s wording.
Import notes
This PDF did not yield chapter bookmarks. The parser used 15-page groups, so the preface had to be located inside “Pages 1–15” rather than selected by its title.
Matthew J. Van Cleave, Introduction to Logic and Critical Thinking, version 1.4, 2016. Audio adaptation by DocsToAudio.

This book has been created to help you make decisions about practical conservation management by providing an assessment, from the available scientific evidence, of what works and what does not work in conservation. It also tells you if no evidence has been found about whether or not a conservation intervention is effective. This is the 2020 edition of What Works in Conservation, which was first published in 2015 and is updated annually.
What we actually tested
Input
OBP Introduction chapter PDF · 10 file pages, including cover and credits · 1 detected section.
Preparation
Selected the opening body paragraph on file page 3 (printed page 1). Left out the cover, copyright page and following heading. Removed a space before a comma introduced by PDF extraction.
Import notes
The chapter download is much smaller than the whole book. It imported as one section, so front matter still needed to be excluded manually.

How to Convert an eBook or PDF into Audio
Download a supported file
Choose PDF, EPUB, DOCX or TXT. If a book offers several versions, start with EPUB for flowing prose or TXT for a simple text-only edition. Check its license and local availability.
Upload it to DocsToAudio
Open the PDF to MP3 converter and upload your file. Review the detected sections before continuing.
Choose what you want to hear
Select the relevant chapters or pages. Exclude contents lists, source notices and other material you do not want narrated. Start with a short section for an unfamiliar file.
Review the text and choose a voice
Check reading order, headers, footnotes and unusual symbols. Choose a voice and speed that suit the document. Standard voices are free; Premium voices use credits.
Convert and download
Export MP3 for broad player compatibility, or M4B for a single audiobook file with chapter marks. Listen to a short section before converting more.
A note about PDFs
Scanned pages may need OCR first. Tables, formulas and multi-column layouts may not produce a natural reading order. Review the extracted text rather than assuming every PDF is ready to narrate.
03 / GOOD TO KNOW
eBook Download & Conversion Questions
Where can I download free eBooks and PDF books?
Start with Project Gutenberg or Standard Ebooks for classics, OpenStax or BCcampus for textbooks, the Open Textbook Library for course discovery, and Open Book Publishers for academic books. This guide links one downloadable example and one actual audio case for each source.
Should I choose EPUB or PDF for listening?
When the same book is available in both formats, EPUB is often a useful starting point for flowing text and chapter navigation. PDF is useful for reports and textbooks, but columns, page furniture and formulas can require extra review. Check the extracted text either way.
Can DocsToAudio read scanned PDFs?
A scanned page may contain an image rather than selectable text. Such a file may need OCR before audio conversion. Check whether you can select and copy the text, and review the upload result before proceeding.
Can I convert these books for free?
DocsToAudio offers free Standard voices. Premium voices use credits. The excerpts on this page use a Standard voice; see the pricing page for current plan details. See pricing.
Can I share the audiobook I create?
Free access to a file does not automatically grant permission to publish an audio version. Check the specific work, edition, license and your country’s copyright rules. This is particularly relevant when using U.S. public-domain collections from the UK or Europe.
