Installation & Usage: A Step‑by‑Step Guide

Downloading the Application

Begin by visiting the official BookTranslator website and clicking the Download button for your operating system. The installer is available for Windows 10/11, macOS 11+, and Linux distributions (deb and rpm packages). The file size is under 120 MB, ensuring a quick download even on modest connections.

Installation Process

Windows: Run the .exe installer, accept the license agreement, and choose the default installation path. The wizard will also install the necessary .NET runtime automatically.
macOS: Open the .dmg file, drag the BookTranslator icon into the Applications folder, and confirm any security prompts.
Linux: Use sudo dpkg -i booktranslator.deb (or the rpm equivalent) and resolve any dependency warnings with sudo apt-get -f install.

First‑Time Setup

Upon launch, you’ll be guided through a brief onboarding wizard. Create a free account or sign in with Google/Apple ID to sync your translation history across devices. The wizard also prompts you to set your preferred output language, default tone, and whether you wish to enable the bilingual comparison view by default.

Translating a Book

To translate, click the “Add Book” button, select an EPUB or PDF from your file system, and choose the target language. If you have a custom glossary, upload it in the Settings → Glossary panel. Press Start Translation and watch the progress bar. For large files, BookTranslator splits the content into manageable chunks, displaying a live estimate of remaining time. Once finished, you can download the translated file, export it back to EPUB/PDF, or view it instantly in the built‑in reader.

Troubleshooting Common Issues

If the translation stalls, verify your internet connection and ensure the application has permission to access the network. For PDF files with complex layouts, use the “Advanced OCR” toggle to improve text extraction. Should you encounter any errors, the Help → Support menu provides a one‑click report that includes diagnostic logs for faster resolution.

BookTranslator runs on Windows 10/11 (64‑bit), macOS 11 (Big Sur) or newer, and major Linux distributions (Ubuntu 20.04+, Fedora 33+). It requires at least 4 GB RAM, a dual‑core processor, and a stable broadband connection for AI processing. No additional software dependencies are needed beyond the standard runtime components installed automatically during setup.

Frequently Asked Questions

Is BookTranslator free to use?

The core application is free and includes unlimited translations for books under 20,000 words. Larger projects require a modest subscription or pay‑per‑page credits.

Can I translate a scanned PDF?

Yes. Enable the “Advanced OCR” option in Settings. The AI will first extract the text and then perform the translation while preserving page layout.

How does the bilingual comparison view work?

After a translation finishes, the built‑in reader displays the original and translated texts in parallel columns. You can toggle line‑by‑line sync, highlight differences, and copy sections directly.

Is my data safe when I upload a manuscript?

All files are encrypted with TLS during upload and stored using AES‑256 encryption. BookTranslator complies with GDPR, CCPA, and does not retain your content after the translation session unless you opt‑in to cloud storage.

Can I customize terminology for technical books?

Absolutely. Upload a CSV glossary in Settings → Glossary. The AI will prioritize these terms, ensuring consistent usage of industry‑specific language throughout the translation.
