## AI TransPDF

AI TransPDF targets the situation where machine translation usually breaks down: real documents with complex formatting. Instead of translating text and leaving you to rebuild the layout, it processes PDF, PPTX, XLSX, DOC, EPUB, SRT, HTML and TXT files and returns a result whose tables, images and formulas still sit where they should. Scanned and image-based documents are also supported, so photographed contracts or quot; ; print-to-PDF reports can be translated without manual retyping.

The engine is built on large language models rather than classic statistical or rule-based machine translation, which is why the output reads more like human phrasing and handles context better. Because that approach is slower, translation of a dense document can take anywhere from a minute to more than ten minutes. The service openly notes that its results are best-in-class for AI translation but should not be treated as certified translations for legal or professional use.

Beyond raw translation, AI TransPDF layers on document-level conveniences: an AI summary of the translated file, a preview mode to check results before downloading, and post-editing that lets you repair seals, formulas and fine formatting details. The platform reports several hundred thousand translated files and users, and operates on a pay-per-use model with a free daily quota so you can evaluate quality before committing.

**Pricing & Plans:** AI TransPDF is not a free service — it is a paid pay-per-use tool that charges based on the volume of text processed. To let people test it, the platform provides a free daily trial quota. The team states that prices are reviewed periodically as large language model inference costs change. Check the pricing page for current per-document or per-volume rates.

- **Format-preserving translation:** Keeps the original layout of PDF, PPTX, XLSX, DOC, EPUB, SRT and HTML files, including tables, images and formulas.
- **80+ language support:** Translate documents between more than 80 languages, with source and target language selection at upload time.
- **Scanned document handling:** Works on image-heavy and scanned files, so PDFs created from paper or exported reports can be translated without retyping.
- **AI document summary:** Generates a condensed AI summary of the translated document so you can grasp the content quickly.
- **Post-editing tools:** Adjust formatting details after translation and repair elements such as seals and formulas that automated conversion can disturb.

**Strengths:** Handles formatted documents that plain-text translators mangle, keeping tables, images and formulas in place; Broad file-type coverage (PDF, PPTX, XLSX, DOC, EPUB, SRT, HTML, TXT) in one tool; Built-in AI summary and preview reduce the need to read an entire translated file just to check it; Free daily quota lets you test translation quality before paying

**Limitations:** Large language model translation is slow — a long document can take over ten minutes; Explicitly not recommended for professional or legally binding translations; Documents are stored encrypted on the servers for history, which may concern privacy-sensitive users

## Readable

Readable is a Japanese AI translation service focused specifically on PDFs. Rather than exporting text and losing the document's structure, it translates the file as a document: tables, images and diagrams keep their original positions, so academic papers, reports and manuals remain readable and do not need to be rebuilt by hand. This is the feature the product leads with, and it is the main reason teams use it instead of a generic text translator.

The service is designed for heavy documents. Pro Premium and Business plans translate files up to 1,000 pages and 200 MB in one pass, while the entry Pro Standard plan covers up to 100 pages and 50 MB. Translations are unlimited on a flat monthly fee and finished files can be downloaded as often as needed. A glossary function lets you pin down how product names, abbreviations and research terminology are rendered, which keeps wording consistent when several people review the same set of documents. Online files can also be translated through a Chrome extension.

Readable supports more than 200 source languages into Japanese, with the Pro Standard plan focused on English-to-Japanese and Pro Premium opening up the full language range. You can choose between the service's own engine and a ChatGPT-based translation engine depending on the document, and the site notes that a separate paid DeepL subscription is not required. Plans start at 800 yen per month, a 7-day free trial is offered, and a Business/Kakenhi option with quotes and invoicing is available for organisations — security reviews and supporting documentation are handled as a separate paid service.

**Pricing & Plans:** Pro Standard is 800 yen per month (English-to-Japanese, up to 100 pages/50 MB per file) and Pro Premium is 4,000 yen per month (200+ languages, up to 1,000 pages/200 MB), both unlimited in translation count. A Business/Kakenhi plan is quoted on request for teams and invoicing needs, and there is a 7-day free trial limited to one use per person or company.

- **Layout-preserving translation:** Tables, figures and diagrams stay where they were, so context and data structure survive translation and you can share the result as-is.
- **Large-file capacity:** Pro Premium and Business plans accept a single file of up to 1,000 pages and 200 MB, so long reports and manuals do not need splitting.
- **Custom dictionary:** Register your own glossary so product names, abbreviations and internal terminology always come out with the same wording.
- **Unlimited translations:** Translate and download as often as you like on a flat monthly plan, and work with online files directly through the Chrome extension.
- **Selectable AI engines:** Choose between Readable's own engine and a ChatGPT-based engine depending on the document, without paying separately for a translation subscription.

**Strengths:** Keeps original PDF layout, so no manual rebuild of tables or diagrams; Unlimited translations on a flat monthly fee from 800 yen; Glossary registration keeps terminology consistent across a document set; Handles very large files (up to 1,000 pages / 200 MB on higher plans)
