Compare the key benefits of in-browser client processing compared to traditional cloud tools.
| Comparison metric | Extract-OCR (In-Browser) | Standard Cloud Converters |
|---|---|---|
| Data Privacy | Complete privacy. Files are processed locally on your device and never uploaded. | Low. Documents are uploaded, processed, and potentially cached on third-party cloud servers. |
| Speed & Network Usage | Instantaneous processing without waiting for long upload or download times. | Requires high bandwidth to upload large images and download generated bundles. |
| Security Threat | Zero danger. No external database store, no potential for leak vectors. | Susceptible to server-side attacks, hacks, and unencrypted databases. |
| Availability & Caps | 100% free with infinite scans and zero subscription popups. | Usually caps uploads, limits free page counts, or hides tools behind paywalls. |

Unlike standard conversion tools that send your documents to a remote server, our tool loads Tesseract.js (an OCR engine powered by WebAssembly) directly in your browser. All text recognition is processed locally on your processor, ensuring your files never leave your computer.
Yes! Our tool loads your PDF, renders each page dynamically onto an HTML canvas, and runs the OCR scanner on the canvas pixels. This allows you to extract text from scanned documents, book pages, and layouts.
Because everything runs on your device, there are no artificial file limits. However, processing very large PDFs (e.g., hundreds of pages) can take some time or consume system memory depending on your computer or phone specifications.
You can convert images (PNG, JPG, WebP) to PDF documents, extract all pages of a PDF as separate PNG images in a ZIP file, extract standard text layouts from digital PDFs, or convert image formats (such as converting JPG or PNG files into WebP).
Absolutely. Because it runs 100% client-side (no background server uploads), it is the safest possible way to process sensitive contracts, tax forms, or personal IDs. You can even run this page entirely offline once loaded!
