How do I make a scanned PDF searchable in Adobe Acrobat?

Open your PDF in Acrobat. Go to All tools > Scan & OCR. Pick your pages and language. Click Recognize Text. Save your new searchable PDF.

If my scan is blurry or low quality, will OCR still work in Acrobat?

OCR works best with clear scans. If your scan is blurry or low quality, it may not find all the words. Try to scan at 300 dpi or higher for better results.

I have three scanned receipts with overlapping shadows and a missing merchant line. Clean up the scans, sharpen printed text, and produce a combined PDF of all receipts in chronological order for expense submission by [deadline=Friday].

when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed.

Finance dislikes scans that hide merchant names. Improve the scanned receipts by removing shadows, enhancing contrast for the merchant lines, rotate and crop to the receipt margins, and include a one-line note identifying any data that could not be recovered and why, so approvers won’t reject the expense pack.

when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed.

CDecide — “help me choose”I scanned seven paper receipts after a site visit; three are partly unreadable and one lacks…+

I scanned seven paper receipts after a site visit; three are partly unreadable and one lacks the merchant name. If I clean them aggressively I might be accused of fabricating evidence; if I ask the team to resubmit, I’ll miss the monthly cutoff. Help me decide: should I produce cleaned images with an attached affidavit explaining what I restored, submit what I have and chase originals later, or ask for reprints now and miss the cutoff? Describe the likely outcome with finance for each choice and recommend the route that minimizes audit risk while keeping our reporting timely.

when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed.

OCR stands for Optical Character Recognition. It is important for scanned PDFs because it changes pictures of words into real text you can search, copy, or edit. Without OCR, you can only look at the pages like photos.

OCR works best with clear scans.
If your scan is blurry or low quality, it may not find all the words.
Try to scan at 300 dpi or higher for better results.

Acrobat gives this message if your PDF page already has real text, not just an image. OCR is only for pages that are pictures, like scanned paper. If you see this error, you do not need OCR because the text is already there. Check your PDF: if you can select or copy words, it already has text.
