PDF TRANSLATION · A PRACTICAL GUIDE
PDF Translator for Books and Documents
Translate a report, paper, manual, or book in Seka. Start with the right source, choose your language and terminology, and keep the original close while you read.
First, try selecting and copying a sentence from your PDF. Readable text is a good starting point; image-only or garbled pages need extra OCR checks. Use the table below to decide what to inspect before starting a full document.
What kind of PDF do you have?
A PDF can mix text pages and scans. Check more than the cover before choosing your review points.
| What you see | What it tells you | What to do next |
|---|---|---|
| A copied sentence is readable | The sampled page has usable text. Other pages may differ. | Copy a sentence from the beginning, middle, and end. Check the order of words in columns. |
| You can see words but cannot select them | The page may be an image, or selection may be restricted. | Check document permissions and whether the page is a scan. Plan to compare OCR text with the image. |
| Copied words are garbled or run together | A text layer exists, but extraction is not reliable for this passage. | Try a clearer source. Inspect names, numbers, and punctuation after processing. |
| Tables, columns, or formulas carry the meaning | Correct words alone will not prove that relationships survived. | Compare row labels with values and formulas with their explanations in the source. |

A fluent sentence can still contain the wrong number
This small library notice was written for this guide. The second panel deliberately introduces recognition errors so you can see what to check; it is not measured Seka output.

- 14 → 1A: a letter has replaced a digit.
- €12.50 → €1250: a missing decimal changes the amount.
Check the source text first, then the translation. Smooth wording cannot establish that a number was recognized correctly.

Can Seka translate a scanned PDF?
Scanned pages need OCR before translation. Recognition quality depends on scan clarity, layout, and language. Compare names, numbers, tables, and fine print with the original; do not assume translation will correct words that OCR misread.
How is this different from a quick PDF translation tool?
This flow handles a document as one reading task. You set language, style, and glossary before submission, then review sections of the translated text. It is still important to check exact figures, warnings, and OCR-sensitive passages against the source PDF.
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.
