Download sample
Select English. Download the PDF and search for INVOICE, 148.50, DELIVERY and 2048. Both pages should look like the sample, with text you can select and copy.
What to expect
Each page is recognized as an image, in order. English, Russian and mixed recognition are available. OCR can misread letters, numbers, columns and tables: review the result. This creates a new PDF from rendered page images and an invisible text layer. Visible page size and rotation are retained; forms, links, bookmarks, attachments and digital signatures are not retained. Existing text is recognized again; image quality is limited by rendering resolution.
Pages are rendered up to 4 megapixels each. Loading and each processing step allow up to 90 seconds; the whole job stops after 10 minutes. Blank pages are marked in the text. No download is offered if processing fails or no text is recognized.
