Frequently Asked Questions
- Is Smart Document OCR free?
- Yes, 100% free with no account required. All 5 OCR modes are available without any limits.
- Are my files uploaded to a server?
- No. All OCR processing runs entirely in your browser using Tesseract.js. Your files never leave your device.
- Why does it download on first use?
- Tesseract.js requires an OCR engine (~8MB) downloaded once and cached in your browser. After the first use, processing is instant without any re-download.
- How accurate is the receipt scanner?
- Accuracy depends on image quality. Clear, high-contrast photos of receipts typically extract merchant name, date, totals, tax, and line items accurately. Blurry or rotated images may need better photos.
- What image formats are supported?
- JPEG, PNG, TIFF, WebP, and BMP images are supported. For best results, use high-resolution, well-lit photos.
- How does the PDF to text mode work?
- For digital PDFs, text is extracted directly (fast, no OCR needed). The tool uses pdfjs-dist to read embedded text from each page with page separators included in the output.
- Can I process many images at once?
- Yes — use the Batch OCR tab to drop multiple images. They are processed one by one with a progress counter, and you can download all results as a single ZIP file.
- Does it work on mobile?
- Yes, Smart Document OCR works on all modern browsers including mobile Safari and Chrome, though processing may be slower on older devices.
