Note: the first run downloads the ~10 MB English language model. Each page is processed one at a time — a 5-page set takes about a minute on a typical laptop.
Scan Digitisation Help
Need whole record sets digitised into searchable archives? Submit your details for assistance.
Open in any PDF reader and use Ctrl+F to search the recognised text.
What makes it "searchable": the PDF keeps the original scan as the visual page, while OCR text is embedded invisibly underneath — so you can search, select and copy text while the document still looks exactly like your scan.
Perfect for
● Making old invoices and shipping bills searchable
● Building searchable archives for audits and compliance
● Sharing scans that reviewers can search and annotate
Scanned PDFs are just pictures — you can't search them. This tool runs OCR with Tesseract.js in your browser and layers the recognised text invisibly onto each page with jsPDF. The result looks like your scan but behaves like a typed document: searchable, selectable and copyable.
For plain text extraction use the OCR Text Extractor, and for combining or splitting the output PDF use PDF Tools.
Frequently Asked Questions
How many pages can I process?
As many as you like — pages are processed one at a time in order. For very large sets, allow a minute or two; keep the tab in the foreground while it runs.
Is the text layer editable after export?
The text layer is selectable and copyable in any PDF reader. To fix recognition errors, extract the text first, correct it, then rebuild — or use our digitisation service for large clean-ups.
Are my scans uploaded?
No. OCR and PDF building run entirely in your browser. Your documents never leave your device.
How does the OCR PDF generator work?
It converts scanned images into searchable PDFs with an invisible selectable text layer, using Tesseract.js and jsPDF entirely in your browser.
Is the OCR PDF Generator free to use?
Yes. The OCR PDF Generator is 100% free for personal and commercial use — no registration, login or payment required.
