Make Scanned PDF Searchable for Records
Record archives are much easier to work with when a scan becomes searchable, but the OCR step should still match the sensitivity of the file. Runs locally in your browser. No uploads.
Use this workflow to run local OCR on scanned records, validate the output, and keep the original scan alongside the searchable copy.

When to use this tool
- You need a predictable local workflow for sensitive files.
- You need a repeatable review process before sharing output.
Step-by-step instructions
- Prepare the source file(s) and expected output scope.
- Run the local operation in your browser.
- Review the result and export the final file.
Limitations and caveats
- Output quality depends on source file quality and device performance.
- Very large files may be constrained by browser memory.
- Always re-check critical pages before sharing externally.

Check scan quality before you run OCR
OCR works best when the source scan is upright, readable, and not overly compressed.
If the record set is mixed quality, split problem pages out first instead of forcing one pass over everything.
Generate the searchable copy locally
Run OCR on the pages that need searchability and then test a few names, dates, or reference numbers in the output.
Keep the original scan untouched as the source record while the searchable version becomes the working copy.
- test search on a few known terms
- copy and paste from key pages to spot OCR issues
- split oversized records into smaller batches when needed
Store the result in a way records staff can trust
Use a naming convention that distinguishes the original scan from the searchable working copy.
If the record is sensitive, minimise how many intermediate exports you keep after validation.
FAQ
Why keep the original scan after OCR?
Because the OCR copy is a processed working version. The original scan remains the safer source record if anything needs to be regenerated or rechecked.
How do I confirm that the PDF is searchable?
Use search, text selection, and copy-and-paste on a few important terms before treating the OCR output as complete.
What if the scanned record set is very large?
Split it into smaller batches first. That is usually more reliable than running one oversized OCR job in the browser.
Does this workflow upload the scanned records?
No. The OCR step runs locally in your browser.
