Convert eBooks to PDF privately — no upload, no server, 100% in your browser
EPUB (Electronic Publication) is the most widely used open standard format for digital books and publications. Created by the International Digital Publishing Forum (IDPF) and now maintained by the W3C, EPUB files are supported by virtually every e-reader app — including Apple Books, Google Play Books, Kobo, and Adobe Digital Editions. However, there is one major exception: Amazon's Kindle ecosystem uses its own proprietary formats (MOBI, AZW3), and PDF remains the universal fallback that works on every device, every platform, and in every professional context. Converting EPUB to PDF is a common need for many users. Students need to submit eBooks as PDFs for coursework or shared reading. Professionals want to annotate digital books in PDF readers like Adobe Acrobat. Authors and publishers need to create print-ready proofs from their EPUB source files. And anyone who wants to read an eBook on a device that doesn't support EPUB — or share a document without worrying about reader compatibility — reaches for PDF as the universal format. Most free online EPUB-to-PDF converters upload your file to a remote server for processing. This introduces serious privacy concerns: your book, your manuscript, or your proprietary document leaves your device and sits on someone else's infrastructure. Some services retain files for 24 hours, others longer. With EverydayTools.io's EPUB to PDF Converter, the conversion happens entirely inside your browser using JavaScript — your file never leaves your device at any point. Our tool uses two powerful open-source JavaScript libraries working together. JSZip unpacks the EPUB file (which is essentially a ZIP archive) and reads its internal XML structure — including the spine, manifest, and chapter content. Then jsPDF renders the extracted HTML content into a properly formatted PDF document. Images are inline-encoded as base64 data URIs so they appear correctly in the output PDF without any server round-trips. Customization is a key differentiator of this tool. Most free converters give you no control over the output — you get whatever page size and margins their server produces. Our converter lets you choose your page size (A4, A5, A3, Letter, or Legal), page orientation (portrait or landscape), margin width (none, 10mm, 20mm, or 30mm), and base font size (10pt to 18pt). The font size control is especially useful for accessibility: if you need a large-print PDF, simply dial the font size up to 16pt or 18pt. Additional options let you include or exclude images from the source EPUB, generate a table of contents page prepended to the PDF, and strip the cover image if you want a clean document without a cover page. Batch conversion is also supported — you can load multiple EPUB files and convert them all in sequence, downloading each resulting PDF individually. EPUB files have a defined internal structure. The container starts with META-INF/container.xml, which points to an OPF (Open Packaging Format) file. The OPF lists the manifest — all the resources in the EPUB — and the spine, which defines the reading order of chapters. Our converter reads this spine order, processes each chapter in sequence, inlines all referenced images, and concatenates the chapters into a single long HTML document. That document is then rendered into a multi-page PDF by jsPDF. It is important to set realistic expectations about formatting fidelity. EPUB files can contain complex CSS layouts, custom embedded fonts, multi-column text flows, and interactive EPUB3 content. Client-side browser rendering cannot perfectly replicate all of these layouts in PDF form — complex fixed-layout EPUBs may reflow or lose some styling. For standard prose eBooks (novels, non-fiction books, academic texts), the output quality is excellent. For complex magazine-style layouts or fixed-format children's books, a server-side rendering tool may produce better results. DRM (Digital Rights Management) protected EPUBs cannot be converted by any browser-based tool, and ours is no exception. DRM encryption is applied at the file level by the publisher or retailer, and decrypting it without authorization is legally prohibited in most jurisdictions under laws like the DMCA. If you own a DRM-free EPUB — purchased from a DRM-free retailer, obtained from Project Gutenberg, or authored yourself — conversion works seamlessly.
Understanding EPUB and PDF Conversion
What Is the EPUB Format?
EPUB stands for Electronic Publication and is an open standard eBook format developed by the W3C. An EPUB file is actually a ZIP archive containing XHTML or HTML chapters, CSS stylesheets, images, and XML metadata files. The OPF (Open Packaging Format) file defines the spine — the ordered reading sequence of chapters. The toc.ncx or nav.xhtml file provides navigation and table of contents information. Because EPUB is based on web standards (HTML, CSS, XML), it is inherently reflowable: text adjusts to the screen size and the reader's preferred font settings. This makes it excellent for e-readers but requires some transformation when converting to a fixed-layout format like PDF.
How Does Browser-Based Conversion Work?
The conversion process has several distinct steps. First, JSZip opens the EPUB file as a ZIP archive in memory. It reads META-INF/container.xml to find the OPF package document, then parses the OPF to get the manifest (all files and their types) and spine (reading order). For each chapter listed in the spine, the XHTML content is read and processed. Image src attributes are replaced with base64-encoded data URIs so images appear inline without network requests. All chapters are concatenated into a single HTML document with page-break CSS rules between them. Finally, jsPDF's html() method renders this HTML into a PDF using html2canvas, which captures the DOM as a canvas image and encodes it into the PDF file. The result is a Blob that is offered for download using a temporary object URL.
Why Convert EPUB to PDF?
PDF (Portable Document Format) is the gold standard for document sharing and printing. Unlike EPUB, which reflows text dynamically, PDF preserves the exact layout, fonts, and pagination as intended. This makes PDF ideal for documents that need to look the same on every device — academic papers, business reports, annotated reading copies, and print proofs. PDF is universally supported: every operating system, every browser, and most devices can open PDFs without any additional software. Many platforms also require PDF specifically for submission — legal filings, academic submissions, grant applications, and publishing platforms all expect PDF. Converting your EPUB library to PDF ensures long-term accessibility regardless of which software or device you use in the future.
Known Limitations of Client-Side Conversion
Browser-based EPUB-to-PDF conversion has inherent limitations compared to server-side rendering with headless Chrome. Complex CSS layouts (multi-column text, fixed-layout EPUB3 files) may not render perfectly and could reflow or lose styling. Custom embedded fonts defined in the EPUB's CSS may fall back to system fonts in the PDF output. Very large EPUB files (over 50MB) may be slow to process in the browser and could hit memory limits on low-end devices. JavaScript-heavy EPUB3 interactive content (quizzes, animations, media overlays) is not supported. DRM-encrypted EPUBs cannot be processed at all. For standard prose eBooks — novels, non-fiction, textbooks — the output quality is generally very good. For complex visual layouts, a professional desktop application may be more suitable.
How to Convert EPUB to PDF
Upload Your EPUB File
Click the upload zone or drag and drop your .epub file directly onto it. You can add multiple EPUB files for batch conversion — each will be queued and converted in sequence.
Choose Your PDF Settings
Select your preferred page size (A4, Letter, etc.), orientation, margins, and font size. Enable the Table of Contents option to add a TOC page at the start, or enable Remove Cover to strip the cover image from the output.
Click Convert to PDF
Press the Convert to PDF button. The conversion runs entirely in your browser — no file is uploaded anywhere. Larger EPUBs may take 30–60 seconds to process. A spinner indicates progress for each file.
Download Your PDF
When conversion is complete, a Download PDF button appears for each file. Click it to save the PDF to your device. The filename is automatically set to match your original EPUB filename.
Frequently Asked Questions
Can this tool convert DRM-protected EPUB files?
No. DRM (Digital Rights Management) protection encrypts the EPUB file so that only authorized apps with the correct decryption key can open it. Examples include books purchased from Amazon Kindle, Apple Books with FairPlay DRM, or Adobe-locked EPUBs. Our browser-based tool cannot decrypt these files, and attempting to do so would be illegal in most countries under laws like the DMCA. Only DRM-free EPUBs — such as those from Project Gutenberg, Standard Ebooks, or DRM-free retailers like Smashwords and Bookshop — can be converted with this tool. If you authored the EPUB yourself, it will be DRM-free and fully compatible.
Is my file private? Does it get uploaded to a server?
Your file is 100% private. Unlike most online EPUB-to-PDF converters that upload your file to a remote server for processing, our tool converts entirely inside your browser using JavaScript. The EPUB is read from your local disk into browser memory, processed with JSZip and jsPDF, and the resulting PDF is downloaded back to your device. No data is sent over the network at any point. This means your personal documents, manuscripts, proprietary reports, or private eBooks remain completely on your device throughout the entire process. There is also no account required and no file size tracking.
How accurate is the formatting in the converted PDF?
Formatting fidelity depends on the complexity of the EPUB. For standard prose eBooks — novels, non-fiction books, academic texts — the output is generally clean and well-formatted. Text, headings, paragraphs, and basic styling are preserved reliably. Images are inlined and scaled to fit the page. However, some formatting may not carry over perfectly: complex multi-column CSS layouts may reflow, custom embedded fonts may fall back to system serif fonts, and intricate EPUB3 fixed-layout designs may lose positioning. For production-quality conversion of complex visual layouts (magazines, comics, illustrated children's books), a professional desktop application with full CSS rendering support will produce better results.
Why is the PDF file size larger than the original EPUB?
PDF files are typically larger than EPUBs for several reasons. EPUB is a highly compressed ZIP-based format — images and text are stored in a compressed archive. When we extract and process the content, images are embedded as base64-encoded data URIs inside the PDF, which adds approximately 33% overhead compared to raw binary. Additionally, jsPDF renders pages using html2canvas, which captures each page as a raster image at the specified resolution — this is less space-efficient than a vector PDF. For a typical novel-length EPUB (300–500KB), the output PDF may be 2–10MB depending on image content and page settings. EPUBs with many high-resolution images will produce proportionally larger PDFs.
What fonts appear in the converted PDF?
The converted PDF uses system fonts for rendering. Our tool applies Georgia (a serif font) as the default typeface, with Times New Roman as fallback — these are standard print fonts that suit most book content well. If the original EPUB specifies custom embedded fonts (such as a publisher's branded typeface), those fonts will not carry over into the PDF, because embedding arbitrary font files in a browser-based PDF generator is not feasible without server infrastructure. The base font size you set in the controls (10–18pt) will apply to the body text throughout the document. Headings are automatically scaled proportionally above the base size for visual hierarchy.
Which page sizes and orientations are supported?
The tool supports five standard page sizes: A4 (210×297mm, the international standard used in Europe, Asia, and most of the world), A5 (148×210mm, a compact booklet size ideal for pocket-sized eBook printouts), A3 (297×420mm, for large-format documents or presentations), US Letter (8.5×11 inches, the North American standard), and US Legal (8.5×14 inches, common for legal documents). Each size is available in both portrait and landscape orientation. Portrait is the default for most books. Landscape is useful if you are converting a document with wide tables, spreadsheet-style content, or horizontal diagrams. Choose the size that best matches how you intend to print or view the resulting PDF.
