Below we show how to OCR convert PDF documents, for free.
Step 1: Select your PDF file
Files are transfered safely over an encrypted
SSL connection. Documents stay private and are permanently removed after processing.
Upload PDF files and choose files from your computer. Can also drag and drop files anywhere on the page.
Step 2: Select the language of your document
The OCR conversion process works best when the language is specified. This way ambiguous words are easier resolved based on the language dictionary.
You'll get a searchable PDF document as a result, where the invisible text is overlayed on the original images at the correct locations.
Accuracy of the OCR process
To inspect the accuracy of the OCR process, open the PDF document, select all text (Ctrl+A) and copy & paste it into a text file.
Higher resolution documents consistently lead to better results. Don't compress your scans before running the OCR process.
Unfortunately we can't guarantee 100% accuracy on the recognized text, this is a best-effort approach.
