Readable: Instant AI PDF Translation English to Japanese

Readable is an AI-powered translation tool built for anyone who needs to quickly understand English PDF documents in Japanese without losing the original formatting. Rather than copying text into a translator and losing tables, images, and structure, Readable processes the entire PDF and reconstructs it with the layout intact, so charts, headers, and columns stay exactly where they belong. This makes it especially useful for research papers, technical specifications, and business documents that rely heavily on visual structure to convey meaning. With a side-by-side viewing mode, users can compare the original English text against the Japanese translation line by line, which is great for double-checking terminology or learning language nuances. Translations are generated in roughly 10 seconds, and a Chrome extension allows for one-click translation directly from the browser. Notably, Readable doesn't require a DeepL subscription to function, though it can integrate with DeepL for users who already have one, offering flexibility depending on budget and translation needs.

1. Open Readable and drag-and-drop your PDF file into the upload area. 2. Note file limits: DeepL Pro users can upload files up to ~20 pages, while DeepL Free users should process one page at a time (Readable itself supports up to 100 pages/50MB). 3. Wait approximately 10 seconds while the AI translates the document. 4. View the translated PDF with the original layout preserved, using the side-by-side mode to compare English and Japanese text. 5. Optionally, use the Chrome extension for one-click translation while browsing.
