PDF Translator for Long Documents and Books

Seka translates the PDFs you actually read from start to finish: reports, papers, manuals, and whole books. Upload a PDF, choose a target language and style, then read the translation as organized long-form text.

PDF workflow

One document, one reading context.

Upload a file, set the language and style, then return to the organized reading view.

A translation flow shaped for long documents

Translate a PDF with Seka's AI reading workflow. Upload a PDF or a scanned document, set language and style, and read an organized translation of the full text.

Upload, configure, and read

Start from the translation entry, choose a PDF from your device, and review the detected file details. Select the target language, pick a translation style, add a glossary when it helps, and confirm the Credits shown for the task.

  • Upload a PDF and check the file summary before continuing.
  • Choose language, style, and optional glossary settings.
  • Open the translated reading view when the task is ready.

Scanned PDFs and text layers

Seka reads PDFs that already contain a text layer, and handles scanned pages with OCR so the pages can be translated. Heavy tables, formulas, and unusual layouts can still come through with errors, so check the passages where exact wording matters.

  • PDFs with a text layer are read without OCR.
  • Scanned pages are processed with OCR before translation.
  • Review tables, formulas, and fine print in the translated text.

Built for long documents, not single snippets

A quick PDF widget translates a page or a copied paragraph. Seka keeps a whole document together: the translation is organized so you can move through it by section and reading position, with the same language, style, and glossary applied from the first page to the last.

  • Translate a full document instead of pasting fragments into a text box.
  • Keep terminology and tone aligned across many pages.
  • Return to the reading view as translation progress becomes available.

Glossary and style controls

Use a glossary for names, product terms, or legal wording that has to stay consistent, then select a style that fits the document. Both settings are part of the translation configuration and are reviewed before you submit.

  • Glossaries keep chosen terms consistent across a document.
  • Style settings guide how the translated text is expressed.
  • The configured language and style stay visible in the task flow.

For readers, authors, and teams

Readers can prepare material in a target language, authors and researchers can check how a translation reads, and teams can run the same workflow on shared documents. Only translate files you are allowed to use: you are responsible for copyright, permission, privacy, and distribution obligations for the source and the translated text.

  • Readers: work through a long document in a chosen language.
  • Authors and researchers: review terminology and style in context.
  • Teams: keep one configuration for a shared document.

Formats, file size, and Credits

Seka accepts TXT, EPUB, and PDF files up to 50 MB each. Before you confirm a task, Seka shows the Credits required for the selected file and options; timing depends on the document and current service workload.

  • Supported upload formats: TXT, EPUB, and PDF.
  • Each file can be up to 50 MB.
  • Review the Credits amount before submitting.

PDF translation questions

Can Seka translate a scanned PDF?

Yes. Scanned pages are processed with OCR so their text can be translated. How well this works depends on scan quality, layout, and language, so review the translation before relying on it.

How is this different from a quick PDF translation tool?

Quick tools are built for a page or a short passage. Seka is built for long documents: you configure language, style, and glossary once, then read the translation as an organized full-length text instead of a wall of extracted lines.

How long does a PDF translation take?

Timing depends on the length of the document, the selected options, and current service workload. The task flow shows progress and indicates when the reading view is ready.

Can I translate any PDF I find online?

Only translate material you are allowed to use. You are responsible for copyright, permission, privacy, and distribution obligations for the source and the translated work.

Translation output can vary by language, genre, terminology, and source quality. Review important passages and use only material you have permission to translate.
