Best practiceFor best OCR accuracy, scan your documents at 300 dpi and avoid extreme brightness settings.
After OCR, you can search, select, and copy text from your scanned PDF as if it were a normal document.
This runs in the Acrobat app - there is no separate API for this task.
Renderable text means the page already has real, selectable text, not just an image of text. Acrobat's OCR feature is designed to convert images of text into selectable text. If the page already has text, the OCR process is not needed and will not run, giving an error. It only works on pages that are pure images.
Acrobat's OCR might struggle with blurry handwritten text. The clearer the scan, the better the recognition. For best results, try to rescan the document at a higher resolution, like 300 dpi, to improve the text clarity before running OCR.
Selecting the correct language helps Acrobat's OCR engine understand the specific characters, spellings, and grammar rules of that language. This makes the text recognition much more accurate. If you choose the wrong language, Acrobat might misinterpret words, leading to many errors in the searchable text.
Both the API and the desktop app perform the same core function: converting image text to a searchable layer. The desktop application is best for single documents or small batches, offering a visual interface to set options and review results. The API is designed for automation, allowing developers to integrate OCR into larger workflows or process many documents automatically without manual interaction. It's ideal for high-volume tasks or building custom solutions.
