I scanned about 60 pages of my lecture notes into a PDF but now I can’t search or highlight any text in it, which is annoying with exams coming up. Is there a way to make the text searchable without rescanning everything? ---

You need OCR, that’s what turns scanned images into actual searchable text. Easiest thing to try: upload the PDF to Google Drive and open it with Google Docs, it runs OCR for free. Honestly though, if your notes are handwritten the results can be rough, it works way better on printed text. ---

I had this exact issue with scanned intake forms last year. You just need OCR, which is a tool that recognises the pictures of words as actual text. The easiest way I found was using PDFcap to make the PDF searchable. It worked brilliantly for me without having to rescan a single page. ---

You need a programme that can recognise text, which is tough with handwritten notes. Upload the file to Google Drive, right-click, and open it with Google Docs to extract the text. Avoid expecting perfect results, as you will definitely need to fix mistakes. I learned this the hard way when digitising my old bakery recipe cards. ---

Had the same thing last month with a stack of handwritten notes. You need OCR to add a text layer, and if the handwriting is neat enough it actually works decently. On Mac I used Preview plus the built in text recognition, but if you are on Windows, OneNote can OCR imported images too. Just don’t expect perfect results with messy handwriting, learned that the hard way during finals. ---

[@SneakySteel](https://pdfbookslib.com/discussions/u/SneakySteel) OneNote is what I’d try too, my old laptop crawls on 60 pages in Preview. Not sure if it works the same on Mac. ---

@Emily.7, OneNote is a sensible fallback, especially on an older laptop. I’d split the 60-page PDF into smaller batches first, then check a few pages carefully since handwriting OCR can miss symbols and names. ---

I use OCR on the existing PDF, so there is no need to rescan. Adobe Acrobat’s “Recognize Text” works well, and free options like OCRmyPDF are good if you are comfortable with it. Check a few pages afterward, especially headings and equations, because handwriting and faint scans can be misread. ---

Run OCR on the file and it’ll add a hidden text layer behind the images, so search and highlighting will just work after that. Most free PDF editors have this built in now, or upload it to Google Drive and open with Google Docs for a quick conversion. Good luck with the exams. ---

@code_pal Batching is what I do with claim packets, 10 to 15 pages at a time, because a bad page is easier to spot that way. I also rename each batch before running OCR so nothing gets overwritten by accident. Recheck dates and numbers afterward, those get mangled the most.
