About Scan PDF (OCR)
Scan PDF runs OCR on scanned or image-based PDFs and adds a searchable text layer. The bundled browser release supports English, Hindi, and Tamil and processes up to 100 pages per run. OCR quality depends on the source scan and the generated text should be reviewed.

When to use this
Use this when a scanned document needs searchable text, digital copy-paste, or OCR-based extraction before sharing or archiving.
Search intent
Before vs after
Before
A photo or scan exists, but the text cannot be searched, selected, or copied because it is only an image.
After
The document becomes searchable and readable so you can find words, share text, and keep records clean and indexable.
Common mistakes
- !Uploading low-contrast scans that OCR cannot read cleanly.
- !Forgetting to rotate pages before OCR so the output gets garbled.
- !Expecting perfect OCR on messy handwriting or complex tables without a cleanup pass.
Compared with alternatives
OCR is more useful than plain image conversion when you need searchable text, file indexing, or better accessibility.
This is better than manually retyping scanned pages when the document still needs to retain its original format.
It is a practical alternative to expensive desktop OCR suites for everyday scanned PDF cleanup.

Frequently asked questions
Which languages does OCR support?
The bundled OCR release supports English, Tamil, and Hindi.
How accurate is the OCR?
Accuracy varies with scan quality, language, font, skew, contrast, and page layout. Always review OCR output before relying on it.
Does it modify my original scanned images?
No. OCR adds an invisible text layer over your existing images — the original scans remain unchanged.
How long does OCR take?
A typical 10-page scan takes 15-30 seconds. Longer documents take proportionally more time as processing is page-by-page.
Can I OCR a PDF that already has some text?
Yes. The tool detects pages without text and runs OCR only on those pages, preserving existing text layers.
