How to finish your task
Review and edit recognized text against the original. Add files and review settings. Create the result, check the preview, actual size and limitations, then download a new file.
Practical example
Select Korean + English for Korean documents. Choose relevant scanned PDF pages, recognize text, edit mistakes in the result field and save TXT.
Scope and limitations
Up to 25 PDF pages are processed. Table structure and equations are not recovered; verify names, amounts and account numbers against the source.
Files are not uploaded to a server. Outputs are new files, so originals remain unchanged. Review the result before saving.
When is this useful?
A PDF may contain selectable text or only a picture of each page. Choose the tool that produces the result you need. Try selecting a sentence or searching for it in a PDF viewer. Scans may need OCR; selectable text can still copy in the wrong order. Base64 represents image bytes; it does not read words in a picture. Use OCR instead and check names, dates and amounts. The first run downloads the engine and language files.
