Termina en tres pasos

Confirme las configuraciones importantes antes de exportar; el lugar de procesamiento siempre se divulga.

Elige un PDF

Read text coordinates, image positions and shared resources per page.

Choose an OCR tier

Auto uses Professional on desktop and lower-memory Fast on mobile; desktop can also select Fast, Professional or Ultimate.

Review and export

Merge native text, images and non-duplicate OCR into a self-contained long page.

Does it work with text PDFs and scans?

Yes. Native words come from PDF text operators; scans and images inside mixed pages use ImgIng PP-OCRv6. Both streams are merged by page coordinates.

How are OCR models selected and loaded?

Auto chooses Professional on desktop and Fast on mobile; desktop users can choose Fast, Professional or Ultimate. On first use the selected model is downloaded and verified from multiple model CDN sources, automatically falls back when one fails, and is then reused from the browser cache.

What if a scan already has an invisible OCR layer?

Normalized OCR output is compared with the page’s native text. Existing phrases are not inserted twice, while unmatched text and the source image remain available for review.

Why export long-page HTML?

HTML keeps page markers, paragraphs, images and recognized image text together. TXT and Markdown provide lighter content-only alternatives.
