What a scanned PDF actually is
When you scan a paper page, the result is an image. A 'scanned PDF' is one or more of those images wrapped in a PDF container. There's no real text inside — just pixels. That's why you can't Ctrl-F search a scanned PDF, and why copy-paste returns nothing. OCR is the step that adds a real text layer.
Why VisionDraft works where free PDF tools fail
Free desktop tools (Preview on Mac, default PDF viewers) usually don't OCR at all. Free online tools often render each PDF page at low DPI to save bandwidth, which kills accuracy on small print. VisionDraft renders every page at high DPI before sending it to the AI vision model, so a 10-point footnote reads as cleanly as a 14-point body line.
Multi-page parallel processing
Long PDFs take forever if pages are processed one at a time. VisionDraft processes several pages concurrently and merges the result in page order. A 20-page scanned PDF typically OCRs in well under a minute, not 10 minutes.
Supported PDFs
Any PDF up to 15 MB, including image-based PDFs (scans), mixed PDFs (some pages text, some scans), and multi-language PDFs (English, Hindi, mixed). Encrypted PDFs need to be unlocked first.
Step-by-step: OCR a scanned PDF
1) Drop the PDF into VisionDraft. 2) Click Reconstruct document. 3) Wait for the page count to complete — pages render with a progress indicator. 4) Skim the result; any low-confidence word is bracketed. 5) Click any bracketed word to zoom into the original page and verify. 6) Copy or export as DOCX.
Common use cases
Legal — make case files searchable for discovery. Real estate — extract clauses from scanned title documents. Healthcare — digitize old patient records. Education — turn scanned reading packets into editable study material. Personal — convert scanned passports, certificates, and tax docs into searchable text.
Multi-language scanned PDFs
Bilingual Indian government PDFs (English + Devanagari) are handled in the same pass with full Unicode output. Mixed Latin and CJK scripts also work, though Devanagari and English have the highest accuracy in the current model.
Searchable PDF output vs text output
VisionDraft returns editable text you can paste anywhere. A 'searchable PDF' (text layer baked into the original PDF) export is on the roadmap — for now, copy the text into your destination tool.
Privacy for sensitive scans
Scanned PDFs often contain PII (IDs, contracts, medical records). Uploads are processed only to extract text — not stored long-term, not shared, and not used for training. For regulated workflows, review your data-handling policy before uploading.

Frequently asked questions
- Is there a page limit?
- Limited by file size (15 MB) rather than page count. 50+ page PDFs work as long as the file is under the limit.
- Can it OCR a mixed PDF (some pages text, some scanned)?
- Yes — every page is processed; text pages are simply read directly.
- Does it preserve page numbers?
- Yes, page boundaries are kept in the output.
- Will my PDF stay private?
- Uploads are processed only to extract text and are not retained long-term.
- Can I get a searchable PDF back?
- Not yet — currently you get editable text. Searchable PDF export is on the roadmap.
- Does Hindi work in scanned PDFs?
- Yes — bilingual English + Devanagari scans are handled in the same pass.
