About this tool

About OCR PDF

Render selected scanned pages and recognize visible text with Tesseract.js in the browser. The selected PDF is processed locally in this browser without being sent to a backend conversion server. Accuracy depends on resolution, contrast, language, handwriting, page angle, and layout.

Use OCR PDF when you need to recognize text in scanned PDF pages. Common uses include extract words from scanned forms, create text from photographed documents, prepare recognized text for manual editing.

How to use OCR PDF

Choose a PDF file.
Enter the pages to recognize and the Tesseract language code.
Choose the OCR detail level.
Run OCR, review the text, and download the TXT output.

What OCR PDF changes

Renders the selected pages into images for recognition.
Creates extracted text output; it does not rewrite the original PDF as a searchable PDF.

Browser-only privacy

The selected PDF is processed by JavaScript running in this browser for OCR PDF. NoLogPDF does not send the file to a backend conversion API, and file names, contents, form values, passwords, and output data are excluded from site analytics.

Limits to know before using OCR PDF

Accuracy depends on resolution, contrast, language, handwriting, page angle, and layout.
OCR is CPU-intensive and can be slow or memory-heavy for many high-resolution pages.

Why NoLogPDF

Built for sensitive files that should stay on your device

NoLogPDF is designed around browser-only processing. The tools load in your browser, run on your computer, and give you honest limits when a format needs server-grade conversion.

No uploads PDFs, images, text, HTML, spreadsheets, and signatures are processed locally.

No signup Open the tool, choose your file, process it, and download the result.

Useful limits Browser-only tools tell you when exact conversion is limited instead of pretending.

Daily workflow Organize, convert, secure, inspect, and clean up files from one simple dashboard.

Local-first privacy

Your data never leaves your device

NoLogPDF is built around privacy principles used by serious teams: minimize data movement, avoid unnecessary collection, and make processing limits visible.

GDPR

Privacy by design

Files are processed locally, so personal documents are not sent to our servers for conversion.

CCPA

No file profiling

NoLogPDF does not need account profiles, uploaded files, or file-processing histories to run tools.

HIPAA

Sensitive-file aware

Useful for private workflows, but not a substitute for your organization's legal compliance process.

Example use cases

Quick answers

Frequently Asked Questions

Is NoLogPDF really free?

Yes. The tools run in your browser and do not require an account or payment gate.

Are my files uploaded?

No. The tools run inside the browser with local JavaScript libraries. There is no conversion API behind the page.

Why are some tools marked Beta?

Some PDF jobs need browser rendering or experimental file parsing. Those tools still work locally, but exact layout can vary.

Can NoLogPDF replace every server PDF converter?

Not for perfect Word/PPT reconstruction or heavy compression. The site favors privacy and transparency over fake perfect results.

Do you use cookies or analytics to track me?

Google Analytics collects basic page-view and site-usage information. NoLogPDF never sends file names, file contents, form inputs, passwords, signatures, or conversion data to Analytics. Your theme preference is saved locally in your browser.

How does the helper answer questions?

The helper answers common questions locally. For a genuinely unmatched question, it can send only the text you typed to protected online support. Files, filenames, document contents, passwords, and conversion results are never included.
