📚 How to Speed Read EPUB Files
Speed Read Books Purchased from E-book Stores
Major e-book stores are increasingly offering EPUB format downloads for purchased books. Books downloadable in EPUB format can be speed-read with this tool.
What is EPUB?
EPUB (Electronic Publication) is an international standard for e-books developed by the International Digital Publishing Forum (IDPF). It is one of the most widely used e-book formats worldwide.
- 📱 Multi-device Support: Readable on smartphones, tablets, PCs, and all devices
- 🔄 Reflowable: Layout automatically adjusts to screen size
- 📖 Open Standard: International standard format independent of specific companies
- 🎨 Rich Content: Integrates text, images, videos, and audio
Why is EPUB Ideal for Speed Reading?
EPUB files store text data in structured HTML format, making it easy for this tool to extract text. This provides the following benefits:
- High-precision Phrase Analysis: Accurately identifies natural Japanese phrase breaks from text data
- Fast Processing: Lightweight compared to PDF, enabling fast loading and parsing
- Fully Local Processing: Files not sent to servers, ensuring safe use of copyrighted e-books

📚 Speed Reading Technology and Japanese Phrase Parsing
What is Center-Display Speed Reading Technology?
This tool uses technology that displays text at a fixed position sequentially, physically eliminating "saccades" (eye movements) that occur in traditional reading. Research shows that approximately 90% of reading time is spent on fixations, with the remaining time spent on eye movements. This technology minimizes movement time and delivers information directly to the fovea, dramatically improving processing efficiency.
In traditional reading, eyes repeatedly perform "saccades" (left-to-right movements) and "fixations" (staying at a point to acquire information). This tool automatically displays text, eliminating the need for eye movement and significantly increasing reading speed.
Importance of Japanese Phrase Parsing
Japanese is a language with unclear boundaries written continuously, making phrase parsing essential for providing an appropriate speed reading experience. Phrases are combinations of "content words + function words" and correspond to positions where humans naturally fixate their eyes.
- Morpheme Units: Too fragmented, disrupting cognitive rhythm (e.g., "今日/は/良い/天気/です")
- Phrase Units (Recommended): Most efficient with natural meaning chunks (e.g., "今日は/良い天気です")
- Sentence Units: Too much information, losing speed reading benefits
This tool determines phrases in real-time through pattern matching of particles, auxiliary verbs, and punctuation. Lightweight implementation without morphological analysis libraries enables fast operation in browsers.
Copyright Protection Through Fully Local Processing
This tool does not send PDF or EPUB files to servers; all processing is done in your browser. This avoids the following risks:
- Copyright Law Risks: Avoids infringement of public transmission and reproduction rights. E-books can be safely used personally.
- Privacy Protection: Prevents leakage of confidential business documents. Confidential materials can be used safely.
- Offline Use: Works in unstable communication environments. Usable on airplanes and subways.
Files are processed only in browser memory and are completely erased upon reload. Designed with security and privacy as top priorities.
Automatic Display Time Optimization
This tool dynamically adjusts display time by considering the following factors, rather than simply dividing by WPM:
- Phrase Length: Longer phrases require more processing time, extending display time
- Punctuation: "。" "！" "？" add 300ms, "、" adds 150ms bonus time
- Kanji Density: Phrases with 3+ kanji have higher cognitive load, adding 100ms bonus time
This achieves a natural reading experience aligned with human cognitive characteristics, rather than a mechanical constant rhythm.
❓ FAQ
A. No, all processing is done in your browser, so files are never transmitted externally. Even if you check the network tab, no communication occurs during file upload.
A. PDF, EPUB, and TXT files are supported. PDFs must have embedded text layers (image-only PDFs not supported), EPUBs should be in standard format, and TXT files should be UTF-8 encoded.
A. Beginners should start at 300-400 WPM, advancing to 500-600 WPM as they become comfortable. Adjust according to content difficulty. Technical books should be set lower, while novels and business books can be set higher.
A. No, this tool only extracts and displays text. If you need to view charts or graphs, please refer to the original PDF separately.
A. Yes, responsive design ensures comfortable use on smartphones and tablets. Perfect for speed reading training during commute times.
A. Space (play/pause), ←→ (navigate 10 phrases back/forward), R (reset), ↑↓ (speed adjustment) are available. Mastering keyboard controls makes reading more efficient.
A. Yes, if the e-book can be downloaded in EPUB format, you can speed read it with this tool. Major e-book stores increasingly offer EPUB format downloads for purchased books. Download in EPUB format from your store's management page.
A. EPUB is better suited for speed reading. EPUB text data is structured in HTML format, enabling high-precision phrase parsing and fast loading. PDF is layout-focused, which can slow text extraction.
A. Yes, this tool uses fully local processing, so copyrighted e-books can be safely used personally. Files are processed only in your browser and never transmitted externally. However, DRM-protected files cannot be loaded unless DRM is removed.
