Acrobat can reject a recognition attempt because a page already contains renderable text. This guide covers that specific error, not every OCR failure.
01 Confirm the error
Check whether the message mentions renderable text. Adobe’s support article explains that this error can appear when existing editable text prevents the recognition workflow from proceeding. Do not assume the same explanation applies to a crash or password error.
02 Test what you need
Try searching for a visible word and copying a short sentence. Compare the copied text with the page. If both tests meet your needs, avoid converting the entire document merely to rerun OCR.
If recognition exists but the words are wrong, use our OCR accuracy guide to review the source and output.
03 Look for an image-only source
Adobe’s first documented solution is to obtain a version without editable text and recognize that version. If you have an original scan, work from a copy and keep the current PDF unchanged.
04 Consider Adobe’s TIFF workaround
Adobe also documents exporting pages as TIFF files and then recognizing the resulting images in Acrobat. Its instructions use Save As and select TIFF; pages are saved as sequentially numbered files.
Try this on a copy of one affected page first. Compare its appearance, recognized text and file size. Do not treat the image-based result as an equivalent replacement for the original document without reviewing everything you need from it.
05 Verify the output
Search distinctive words, copy a sentence and manually compare names, dates and amounts. If multiple pages are involved, check the sequence and confirm that no page was omitted.
Common mistakes
- Applying this fix to an unrelated OCR error.
- Overwriting the original.
- Recognizing all pages before testing one.
- Assuming completion means accurate text.
For a scan that has no searchable text, see the scanned-PDF search guide.
