Extract Text from DjVu

Recover the hidden OCR text already embedded in a DjVu document as UTF-8 plain text or bounded positional XML. This is extraction, not new OCR.

Private results · no network lookup · no quality reduction · files up to 1 GB

XML is a bounded DjVuLibre engine representation. It is not ALTO or hOCR and does not guarantee reading order.

Rights and privacy reminder: Process only documents you are allowed to use. Hidden text, annotations, and scans can contain private or copyrighted material. Results stay in the uploader’s private job and are served as no-store attachments under the existing retention period.

What the DjVu toolkit does

Bounded inspection

Reports page count, native dimensions, DPI and gamma when exposed, bundled structure, hidden text, annotations, thumbnails, and foreground, background, and mask layers.

Source-derived text

Text accuracy and language come entirely from the uploaded source. Convertr does not improve, translate, mutate, or send extracted text upstream.

Native page rendering

Selected pages are decoded by the pinned ddjvu build at their full native dimensions. Unsafe expansion fails explicitly instead of truncating or downscaling output.

Indirect DjVu documents with unresolved component references are rejected. The toolkit never follows component URLs, exposes component identifiers, accepts command scripts, or offers crop and quality switches.

Extract Text from DjVu

Recover only the hidden OCR text already embedded in a DjVu document.

入力
One signature-verified .djvu or .djv file and TXT or positional XML output.
出力
Complete UTF-8 text or sanitized bounded positional XML.
リアル制限
This does not create new OCR, improve accuracy, translate text, or guarantee reading order.
プライバシーとデータ処理
one signature-verified .djvu or .djv file and TXT or positional XML output is uploaded to a compatible Convertr worker only after you start the operation. Processing is automated, and temporary source and result files are deleted automatically after processing rather than retained as permanent storage.

このツールをどのように使うか

  1. Choose one signature-verified .djvu or .djv file and TXT or positional XML output and wait for the page to validate it.
  2. 利用可能な出力または検査オプションを設定し、その後処理を開始します。
  3. Review the reported result and download complete UTF-8 text or sanitized bounded positional XML before the temporary link expires.

一般的な失敗モード

A missing text layer, invalid UTF-8, unsafe XML expansion, malformed document, or workspace exhaustion produces an explicit failure.
