See the difference: Traditional converters break layouts. Our AI understands them.
Free online tools, basic desktop software
Basic text extraction by X/Y coordinates. Like a copy-paste robot that doesn't understand structure. For scanned PDFs or image-based documents? They rely on primitive OCR that produces garbled, unreadable text.
⚠️ Reality Check: Our free Standard mode? Same limitations. It's great for simple text PDFs. But for scanned books, image-based PDFs, or complex layouts? You'll need the paid version.
Powered by our self-developed AI model
Our proprietary AI model "sees" pages like human eyes. It understands document structure, columns, and context—not just coordinates. For scanned PDFs and image-based documents? Our self-developed model excels where free tools fail completely—delivering 99%+ OCR accuracy even with faded text, stains, or handwritten notes.
🎯 Best For: Scanned books, research papers, historical documents, image-based PDFs, technical manuals with diagrams. Where free OCR fails, our self-developed AI model shines.
Cost: $0
But results? Garbled output, broken layouts
Acceptable for simple text PDFs only. Fails completely on scanned documents.
Academic OCR: $0.10-$0.50+/page
Manual formatting: $50+ per book
Used by publishers and researchers. Expensive but accurate.
Professional quality at fraction of cost
Up to 95% cheaper than academic services
Looking to convert PDF to EPUB free? Traditional tools just extract text—preserving the broken layouts from your original document. Our AI understands the structure. It intelligently reconstructs paragraphs, formulas, and images into a true eBook format. The result? Text that flows perfectly on any device.
Use this PDF to EPUB converter free tier to see the difference. Need perfect PDF to EPUB AI reflow for complex academic papers, scanned documents, or dual-column layouts? Upgrade to paid version.
Academic papers are notorious for their dual-column layouts. When converted to eBooks? They break horribly. Our AI detects column boundaries and intelligently merges them into a single, flowing narrative—perfect for reading on phones, tablets, and e-readers.
Turn rigid PDFs into liquid knowledge. We detect LaTeX formulas and reconstruct them perfectly, so they never break when you change font size. Stop reading broken columns on your phone.
Get a true eBook experience with adjustable fonts, dark mode support, and perfect chapter navigation. No more pinch-to-zoom. No more microscopic text.
Pro tip: Your Kindle will thank you. True eBook layout means it remembers your place, highlights work, and dictionaries function normally.
Our Vision Model sees the page like a human. It ignores coffee stains and handwritten notes, extracting only the clean text you want to read.
Standard (Free) Mode: Basic text extraction in your browser. Fast, private, works well for simple documents like novels.
Paid Mode: Advanced AI processing for complex layouts. We charge to cover computing costs and provide sustainable service.

When converting PDF to EPUB format, our AI technology understands semantics—not just coordinates. Here's how the pipeline works:
Read the page like a human—identifying text, images, and structure
Detect columns, headers, footers, captions—and their relationships
Convert garbled formulas into clean LaTeX/MathML markup
Package everything into a standard EPUB that works on all devices

Standard (Fast) Mode - Completely Free, Forever
Paid Version - Our Premium Solution for Complex PDFs
Quick tip: Use this PDF to EPUB converter free in Standard mode to convert PDF to EPUB instantly. If you see broken layouts, garbled text, or messed-up formulas - that's when the paid version makes the difference. Try preview of first few pages free before committing.
Most converters fail at this. Why? They extract text by coordinates—preserving the broken two-column layout from your original document. Our AI reflow technology? It's the ideal solution for dual-column papers.
When you convert two-column PDFs with our tool, the AI detects column boundaries and merges them into a single, continuous flow. IEEE papers, academic journals, research reports—they all become perfectly readable on your Kindle. No more broken text. No more frustration.
PDF Reflow is the process of converting fixed-layout PDF documents into flowable eBook formats where text automatically adjusts to fit different screen sizes. Unlike simple conversion, reflow understands the document structure and reconstructs paragraphs—not just lines.
Why is it better? It addresses the core problem with PDFs: they were designed for printing, not for reading on small screens. Traditional converters just copy text coordinates, breaking layouts and garbling formulas. Our self-developed PDF to EPUB AI model? It analyzes the semantic meaning of your document—identifying columns, headers, captions, and mathematical formulas—then rebuilds everything as a true eBook.
Yes! Our PDF to EPUB AI technology excels at converting scanned PDFs to EPUB format using advanced OCR (Optical Character Recognition) powered by vision models.
When you upload a scanned PDF, our Vision AI sees the page like a human would. It distinguishes between printed text and coffee stains, handwriting, or marginal notes—extracting only the clean content you want to read.
How it works:
Absolutely. Our PDF to EPUB converter free Standard tier handles basic text, but for mathematical formulas when you change PDF to EPUB? You'll want paid processing. Traditional converters? They mangle equations into gibberish. Our AI reconstructs them properly.
Can you convert PDF to EPUB without losing math formatting? Yes—our AI detects LaTeX-style formulas (even when garbled in the original PDF) and converts them into clean MathML that eBook readers render beautifully. Fractions, integrals, matrices, Greek letters—symbols display correctly.
This is especially valuable for STEM students, researchers, and engineers who need to read technical documents on e-readers. Simply upload your PDF with equations, select the paid version, and download an EPUB where every formula is perfectly preserved. No more squinting at broken symbols.
Standard (Free) mode - When converting PDF files to EPUB in this mode, it uses basic text extraction in your browser. It's fast. It's private—files don't leave your device. It works well for simple novels and single-column documents. But it can't handle complex layouts.
Paid version? That's where the magic happens. Our GPU servers analyze your PDF with computer vision, fixing broken layouts, reconstructing formulas, and processing scanned documents via OCR. The result? Perfect EPUBs for academic papers, technical manuals, and scanned books.
Our recommendation: Try Standard mode first for simple documents. See broken layouts or garbled text? Switch to the paid version. Preview first few pages free to see the difference before paying—no commitment required.
When transferring PDF to EPUB, your file is completely safe with us. We get it—you've got contracts, research papers, personal documents. Privacy matters.
The details:
Translation: Your documents never leave our control, and we never keep them longer than necessary.
Standard mode (free)? When turning PDF to EPUB in this mode, it's almost instant. Simple documents finish in 5-60 seconds because everything runs in your browser.
Paid processing takes longer—but delivers much better results. Our self-developed AI model analyzes document structure, not just text coordinates.
⚠️ Important: Paid processing is resource-intensive
Our servers run at high capacity due to heavy compute requirements. Processing time varies from 1 minute to 60+ minutes depending on document size, complexity, and current server load. You can close this page and come back later—your file will be processed in the background. We'll email you when it's ready (or check back periodically).
Typical processing times:
The process includes OCR (for scanned PDFs), layout analysis, formula reconstruction, and EPUB generation using our proprietary AI model. Pro tip: Download preview of first few pages instantly to see quality while the full document processes in the background.
Great question—and the answer depends on your PDF type. Can you convert PDF to EPUB without losing format? Yes, but you need the right mode.
Standard (Free) mode: Preserves basic text and simple formatting. Works great for novels, plain documents, and single-column layouts. But complex layouts? Dual-column papers? Mathematical formulas? Standard mode might disappoint.
Paid version: This is where convert PDF to EPUB without losing format really shines. Our AI understands document structure—not just coordinates. It intelligently merges dual columns, reconstructs LaTeX formulas, detects chapters, and generates proper TOC. The result? Your EPUB looks like a professionally formatted eBook, not a broken PDF dump.
