How your data is processed
SafeOCR downloads and loads the open-source Tesseract.js OCR engine directly into your browser on first use, then performs all text recognition on the client side using your device's processor. Document images are never sent to external servers at any point — making it safe to process contracts, medical records, financial documents, government IDs, and any other sensitive files with complete confidence.
Supported formats & export
Input formats: JPEG, PNG, BMP, TIFF, and WebP (up to 10 files, 20MB each). Output formats: Searchable PDF (with embedded text layer for Ctrl+F searching), Excel XLSX (with automatic table detection and cell mapping), plain text TXT file, and one-click clipboard copy. Recognizes 100+ languages including English, Korean, Japanese, Chinese, Arabic, and all major European languages.
What is SafeOCR?
SafeOCR is a free, privacy-first OCR (Optical Character Recognition) tool that extracts editable, searchable text from images and documents entirely within your browser. Unlike cloud-based OCR services that require uploading your sensitive documents to remote servers — where they may be stored, accessed, or used for AI training — SafeOCR processes everything locally using the open-source Tesseract.js engine. Your contracts, medical records, tax documents, and financial statements never leave your device.
How to Use SafeOCR (3 Steps)
- 1
Upload Your Images
Select up to 10 document images (JPEG, PNG, BMP, TIFF, or WebP, up to 20MB each). Choose the primary document language from the dropdown and select a quality mode — Fast for clean printed text, Precise for complex layouts or lower-quality scans.
- 2
Preview & Enhance
SafeOCR automatically preprocesses your images — converting to grayscale, enhancing contrast, applying binarization, and correcting skew — to maximize recognition accuracy before the OCR engine runs. You can also manually adjust preprocessing settings for fine-tuned control.
- 3
Extract & Export
Review the extracted text with character-level confidence scores highlighted. Export results as a searchable PDF, Excel spreadsheet (with automatic table conversion), plain text file, or copy directly to clipboard. All export processing happens locally on your device.
Why Browser-Based OCR Is Safer
Most online OCR tools — Google Drive OCR, Adobe online services, and free sites — require you to upload sensitive documents to their servers, creating serious privacy risks. A scanned medical prescription, a tax return, or a signed contract uploaded to an unknown service could be stored indefinitely, accessed by employees, leaked in a data breach, or used to train AI models. SafeOCR loads the entire OCR engine directly into your browser, performing all text recognition on your device. Your documents stay on your device from start to finish.
