Why In-Browser PDF Tools Are More Private Than Upload Sites
When you upload a PDF to a remote converter, you trust that server with whatever is inside. Local processing changes the risk model.
PDF to JPG and JPG to PDF Without Uploading
Convert PDF pages to images or build a PDF from photos—locally in your browser.
What this tool does
OCR PDF renders each page locally and runs Tesseract.js (WASM) to extract text from scanned or image-based PDFs. Ideal when Extract Text finds little or nothing because the document is a scan.
How to use it
- Upload a scanned PDF.
- Optionally limit to a page range for faster results.
- Run OCR and download the recognized text as a .txt file.
Common use cases
- Pull text from phone-scanned receipts
- Search old paper archives after digitizing
- Copy quotes from image-only PDF reports
FAQs
- Is OCR uploaded to a server?
- No. Recognition runs in your browser with Tesseract.js. Language data is loaded by the library in your session; your PDF stays on the device.
- How accurate is it?
- Accuracy depends on scan quality, resolution, and language. Clean 300 DPI scans work best. This is free on-device OCR—not a commercial cloud engine.
- Does this create a searchable PDF?
- Currently it exports recognized text as .txt. Use Extract Text for born-digital PDFs that already have a text layer.
- Which language is supported?
- English (eng) by default. More languages can be added later without paid APIs.
