How It Works

Extract text in three steps

Step 1
📂
Upload your PDF

Drag and drop your PDF into the input panel, or click "Browse File" to select it from your device. Any PDF is accepted — scanned documents, text files, image-heavy reports.

Step 2
⚙️
Configure & run OCR

Choose the OCR language from the Options panel. Then click "Run OCR". Tesseract.js renders each page and recognizes text locally — no data sent to any server.

FAQ

Frequently asked questions

Is the OCR PDF tool free to use?
Yes — completely free with no file-size limits, no daily usage caps and no premium tier. All 247 tools on BunchTool are free forever, with no upsells or paywalls.
Is my PDF file safe and private?
Absolutely. Your PDF is processed entirely inside your browser using client-side JavaScript. The file never leaves your device and is never uploaded to any server — not ours, not anyone else's.
Does this tool work offline?
Yes. Once this page has loaded in your browser, the PDF compressor continues to work without an internet connection. All processing happens locally on your device (after Tesseract.js loads).
What file types are supported?
This tool accepts standard PDF files (.pdf). There is no hard file-size limit — PDFs of any size are supported, though very large files (100 MB+) may take a few seconds longer to process on older hardware.
What OCR engine does this tool use?
Typical compression is 40–90% depending on the original content. PDFs with many high-resolution images see the highest reduction. Text-heavy PDFs compress less but still benefit from optimised internal structure and stripped metadata.
