ReadAble

ReadAble (Readable) is an AI-powered PDF translation tool designed to turn English PDFs into natural Japanese in seconds—without destroying the original formatting. Instead of copying text into a separate translator and losing figures, tables, headings, and spacing, ReadAble focuses on keeping the document’s layout intact so the translated file remains readable and close to the source. This makes it especially useful for anyone who regularly reads English research papers, technical specifications, manuals, or business documents and wants a faster way to understand them in Japanese.

Using the service is straightforward: you upload a PDF by dragging and dropping it into the upload area, then wait briefly while the system translates the content. Typical processing takes around 10 seconds, after which the translated output is ready to view. For users relying on DeepL Free, the recommended workflow is translating one page at a time; DeepL Pro users can upload larger PDFs (approximately up to 20 pages). ReadAble is built for speed and convenience, helping you move from “I have an English PDF” to “I can read this in Japanese” with minimal effort.

A key advantage is the reading experience. ReadAble supports side-by-side viewing of the original English and the translated Japanese, so you can quickly cross-check terminology, confirm nuances, and keep your place—useful when reviewing academic arguments, engineering requirements, or compliance language. There is also a Chrome extension that enables one-click translation, which can streamline document handling when you frequently open PDFs in the browser.

ReadAble can be used with DeepL, and it also offers an option to translate without requiring a DeepL subscription, giving users flexibility depending on their plan and needs. Whether you’re scanning a paper for relevant sections, translating a spec to share with a Japanese-speaking team, or trying to understand an English document quickly, ReadAble aims to provide a practical, layout-preserving translation workflow optimized for PDF reading.
