Overview

What Is OCR (Optical Character Recognition)?

Optical Character Recognition (OCR) is the technology that converts images of text — whether from scanned documents, photographs, or PDF files — into machine-readable, editable text. When you scan a paper document or save a fax as a PDF, the resulting file is essentially a collection of images. The text visible on those pages cannot be searched, copied, or edited because the computer sees only pixels, not characters. OCR bridges this gap by analyzing the visual patterns in those images and translating them back into actual text characters.

Our online OCR PDF tool uses one of the most widely used open-source OCR engines in the world. It has been refined over decades and supports more than 100 languages. Our implementation exposes the 16 most commonly used languages with optimized recognition models, delivering high accuracy for printed text in a variety of scripts including Latin, Cyrillic, CJK (Chinese, Japanese, Korean), Arabic, and Devanagari.

What sets our tool apart from server-based OCR services is that everything runs entirely on your device. Your scanned documents are never uploaded to any server. The PDF pages are rendered to images and then processed by the OCR engine entirely on your device. The only network request is to download the language recognition model (typically 1–15 MB depending on the language), and even that is cached for subsequent uses. This architecture makes the tool ideal for sensitive documents — medical records, legal contracts, financial statements, and personal correspondence — where data privacy is paramount.

The tool outputs extracted text in two formats: plain text (TXT) for immediate editing in any text editor, or a structured PDF where each original page's text is placed on a corresponding PDF page. You can also copy the text directly to your clipboard. A confidence score is provided for each page, helping you assess the quality of recognition and identify pages that may require manual review. Whether you are digitizing a paper archive, extracting data from receipts, or making scanned documents searchable, this OCR tool provides a fast, free, and completely private solution.

Features

What This Tool Can Do

A powerful set of capabilities for extracting text from any scanned document or image.

Scanned PDF Recognition

Upload any scanned PDF — whether from a flatbed scanner, mobile scan app, or fax — and the tool converts each page to an image, runs OCR, and extracts every line of text with high accuracy.

Direct Image OCR

Not just PDFs — upload PNG, JPG, TIFF, WEBP, or BMP images directly. The tool applies the same powerful OCR engine to extract text from photographs, screenshots, receipts, and documents.

16 Languages Supported

Choose from 16 languages including English, French, German, Spanish, Chinese, Japanese, Korean, Arabic, Hindi, and more. The engine downloads the appropriate language model and optimizes recognition accuracy.

Confidence Score Reporting

After processing, the tool displays a confidence percentage for each page and an overall score. This helps you quickly gauge recognition quality and identify pages that may need manual review.

100% Private Processing

Your files never leave your device. The OCR engine runs entirely on your device. No server uploads, no cloud processing, no data retention — complete privacy guaranteed.

TXT & PDF Output

Download extracted text as a plain TXT file for easy editing, or as a structured PDF document that preserves page separation. Copy text directly to your clipboard with one click.

Testimonials

Questions from Real Users

See how others use the OCR PDF tool and get answers to common questions.

I have a stack of scanned contracts from our legal department — about 150 pages in a single PDF. The scans are high quality, black text on white paper. Will this tool handle such a large file and produce accurate text?

LJ

Laura Jennings

Legal Coordinator, Chicago, USA

Yes, the tool is designed to handle large multi-page PDFs efficiently. For documents over 50 pages, it automatically adjusts the rendering scale to balance speed and quality. A 150-page high-contrast scan typically takes 5–10 minutes depending on your device. The accuracy for clean, high-resolution black-on-white text is excellent — usually above 95% confidence. You will see real-time progress with a per-page counter so you always know where it stands.

I need to extract text from photographed receipts and invoices that are slightly tilted and have varying print quality. Some are in German, some in English. Can the OCR handle mixed-quality images?

SM

Stefan Müller

Accountant, Berlin, Germany

The OCR engine handles a range of image qualities including slightly tilted or skewed text, varying font sizes, and moderate noise. For best results, process English and German documents separately — select 'English' for one batch and 'German' for another, since the engine optimizes its recognition model per language. Receipts with clear print usually produce 85–95% confidence. Very blurry or extremely low-resolution images may produce lower accuracy.

I'm concerned about data privacy. These are medical records that contain patient information. Is anything uploaded to your servers?

DAP

Dr. Aisha Patel

Healthcare Administrator, Toronto, Canada

Absolutely nothing is uploaded. The entire OCR process runs on your device. Your PDF pages are converted to images in memory, processed by the OCR engine on your device, and the extracted text stays on your computer. The only network request is to download the language model file (a one-time download per language). Your documents, images, and extracted text never leave your computer.

Can I use this tool for Japanese documents? I have scanned pages of handwritten notes mixed with printed Japanese text.

YT

Yuki Tanaka

Graduate Student, Tokyo, Japan

The tool supports Japanese OCR using the 'jpn' language model. Printed Japanese text (kanji, hiragana, katakana) is recognized well. However, handwritten text is significantly harder for any OCR engine — results will vary depending on handwriting clarity. For best results with mixed content, the printed portions will be extracted accurately while handwritten sections may need manual correction.

I tried another online OCR tool but it only allows 5 pages free and then asks for payment. Does this tool have any limits?

CR

Carlos Rivera

Freelance Writer, Madrid, Spain

There are no page limits, no file limits, and no hidden fees. You can process as many documents as you want, as many times as you want, with zero restrictions. Since all processing happens on your device, there are no server costs to pass on. The tool is genuinely 100% free with no premium tier, no account requirement, and no watermarks on output.

FAQ

Frequently Asked Questions

Everything you need to know about using our online OCR tool.

Is this OCR tool completely free?
Yes. There are no hidden fees, no premium tiers, and no page or file limits. You can process as many documents as you need, unlimited times, without creating an account or providing payment information.
Are my files uploaded to a server?
No. The OCR engine runs entirely on your device. Your PDF pages are rendered to images, processed by the engine on your device, and the extracted text stays on your computer. The only network request is to download the language recognition model (cached after first use).
What file formats are supported?
The tool accepts PDF files (including multi-page scanned PDFs), as well as image files in PNG, JPG/JPEG, TIFF, WEBP, and BMP formats. For PDFs, each page is automatically converted to an image before OCR processing.
How accurate is the OCR?
Accuracy depends on the quality of the source document. High-resolution scans with clear, printed text typically achieve 90–99% accuracy. Lower resolution images, unusual fonts, handwriting, or heavily degraded documents will have lower accuracy. The tool reports a confidence score for each page so you can assess quality.
Can it recognize handwritten text?
The OCR engine is primarily designed for printed text recognition. It may extract some clearly written handwritten text, but accuracy will be significantly lower than for printed text. For handwritten document digitization, specialized handwriting recognition tools are recommended.
How long does processing take?
A single-page image typically processes in 5–15 seconds. A 10-page PDF takes about 1–2 minutes. A large 100-page document may take 10–20 minutes. Processing time depends on your device speed, page resolution, and text density. The progress bar shows real-time status.
Can I OCR a document in multiple languages at once?
Currently, the tool processes one language at a time for optimal accuracy. If your document contains text in multiple languages, process it once with the primary language selected. The OCR engine can often recognize common secondary characters (like numbers and Latin characters) regardless of the selected language.
What devices are supported?
The tool works on all modern desktop and mobile devices. For best performance with large files, a desktop device with at least 4 GB of available RAM is recommended.
