OCR for scanned PDFs in portal uploads
Use OCR when a scan is readable, but you need searchable text for review or submission. Keep it secondary when the real problem is a strict upload limit.
When OCR helps
- A portal or reviewer needs searchable text inside a scanned PDF.
- You want to keep the document on-device instead of uploading it to an OCR service.
- You need a better balance between readability and file size before submission.
What to verify
- Check scan clarity before running OCR on a blurry document.
- Compare file size before and after OCR if the upload limit is strict.
- Keep an original copy in case the destination only wants the raw scan.
Do not turn on OCR automatically when your main goal is meeting a strict size limit. OCR can increase the final file size, and not every portal needs it. If your priority is meeting a strict size limit, start by getting a version that fits without OCR and use Choose the right target size.
