ReadFlow: EPUB Translator

ReadFlow helps you make books and documents easier to read on your favorite e-reader.

Translate your own EPUB books into another language, or convert PDFs into clean EPUB files that flow better on small screens. Preview the result first, then use credits only when you create the full output.

TRANSLATE EPUB BOOKS

Upload your own DRM-free EPUB, choose a target language, and create a translated preview for free.

If the preview looks good, ReadFlow can create a full translated EPUB while keeping the reading structure as clean as possible.

Great for:
• EPUB books you own
• Study materials
• Long-form reading
• Personal documents
• Language learning
• Reading foreign-language books more comfortably

CONVERT PDF TO EPUB

Reading a PDF often means zooming, pinching, and dragging around a fixed page.

ReadFlow converts PDFs into EPUB files that adapt to your font size and feel more natural on e-readers and reading apps.

Upload a PDF, preview the result, choose your quality mode, and export the full EPUB when you are ready.

PREVIEW BEFORE USING CREDITS

ReadFlow is preview-first.

You can check a sample before spending credits:
• Preview EPUB translations before full translation
• Preview PDF conversions before full export
• Avoid surprises before committing credits

CREDITS EXPLAINED

Credits are used for full PDF exports and full EPUB translations.

EPUB translation credits are based on the amount of text in your EPUB.

PDF export credits are based on document length and quality settings.

If a full translation or export fails, credits are released according to the app’s credit handling rules.

PDF QUALITY MODES

Fast:
Quick and credit-efficient. Best for clean, text-based PDFs.

ACCOUNT-BASED CREDITS

Sign in with Google to keep your credits linked to your account.

Your credit balance can be restored if you reinstall the app or switch devices.

CLOUD-POWERED PROCESSING

ReadFlow processes files on dedicated servers to provide better conversion and translation quality than simple on-device tools.

This also helps avoid draining your phone’s battery or storage during larger jobs.

IMPORTANT NOTES

ReadFlow works best with text-based PDFs and DRM-free EPUB files.

Scanned PDFs, image-heavy files, or complex multi-column layouts may produce mixed results. Use the free preview to check the output before spending credits.

Only upload and translate files that you own or have permission to process.
