คำถามที่พบบ่อย

How does the image to text converter work?

For images, our tool uses Tesseract.js — a powerful OCR engine that runs entirely in your browser. Your images are never uploaded to any server. For PDFs, we extract embedded text server-side using PyMuPDF, and for scanned PDFs, pages are rendered as images and processed with OCR in your browser. Results appear in an editable text box you can copy or download.

What file formats are supported?

We support all common image formats including PNG, JPG, JPEG, WebP, BMP, and GIF. PDF files are also supported — both digital PDFs with selectable text and scanned PDFs containing images. For scanned PDFs, up to 10 pages are processed using client-side OCR for best privacy.

Is my data private and secure?

Yes. Image OCR processing happens entirely in your browser using Tesseract.js — your images never leave your device. For PDF text extraction, files are processed on our server and immediately discarded after extracting the text. No files or extracted content are stored or logged on our end.

What languages are supported?

Our OCR engine supports 100+ languages including English, Spanish, French, German, Chinese, Japanese, Korean, Arabic, Hindi, Portuguese, Russian, and many more. Select your language from the dropdown before processing for the best results. Multi-language documents work best when you choose the primary language.

How accurate is the text extraction?

Accuracy depends on image quality. Clear, high-resolution images with good contrast typically achieve 95%+ accuracy. Handwritten text, blurry images, or unusual fonts may produce lower accuracy. For best results, use well-lit, straight-on photos of printed text and crop out unnecessary borders before uploading.

มีการจำกัดขนาดไฟล์หรือไม่?

For images, there's no strict limit since processing happens in your browser — though very large files may be slower on mobile devices. For PDFs, the maximum file size is 20MB to ensure fast server-side processing. If your PDF is larger, consider splitting it into smaller files first.

Can I extract text from screenshots?

Absolutely! Screenshots are one of the most common use cases. Simply paste or upload a screenshot and the OCR engine will extract all visible text, making it easy to copy text from images, error messages, chat windows, or any on-screen content you cannot normally select.

Can I extract text from a photo of a document taken with my phone?

Yes. Phone photos of documents, receipts, whiteboards, and book pages all work well. For best accuracy, hold the camera parallel to the document, ensure even lighting without shadows, and avoid tilting the page. Cropping the image to just the text area before uploading also improves results significantly.

Does the OCR tool preserve formatting like tables and columns?

The OCR engine extracts text in reading order but does not reconstruct complex table structures or multi-column layouts. Simple single-column text is reproduced accurately. For documents with tables, you may need to manually adjust the extracted text or use the digital PDF extraction mode, which preserves layout better.

How long does OCR processing take?

Processing time depends on image size, complexity, and your device's performance. Most single images are processed in 3 to 10 seconds. The first image may take slightly longer because the OCR engine needs to load the language data file. Subsequent images using the same language process faster.
