About Image to Text (OCR)
Extract text from images free online with FreeToolBox's Image to Text converter, powered by Tesseract.js OCR (Optical Character Recognition). Upload a photo, screenshot, scanned document, or any image containing text, and the tool will extract all readable text you can copy and use. It's perfect for digitizing printed documents, extracting text from screenshots, converting scanned receipts into editable text, or making image-based PDFs searchable.
FreeToolBox's OCR engine runs entirely in your browser using Tesseract.js — no image is ever uploaded to a server. Your documents and photos stay completely private on your device. The tool supports over 100 languages and can handle a wide variety of fonts and text sizes. It's completely free, with no account required and no limits on the number of images you process.
Best use cases for image-to-text OCR
- Screenshots, app panels, and chat captures – Pull text out of screenshots when copy-paste is blocked or inconvenient.
- Receipts, invoices, and expense documents – Extract line items, totals, dates, and vendor details into editable text for finance workflows.
- Printed notes, handouts, and study materials – Turn photo-based notes into searchable text for summarizing, quoting, and reuse.
- Scanned forms, reports, and reference documents – Recover text from image-based PDFs or photographed paperwork without uploading the file.
When should you use Image to Text vs other image tools?
Use Image to Text when your goal is extracting readable content, not editing the picture itself. If the source image is oversized, run it through Image Compress first for easier handling. If the text area needs tighter framing, use Image Crop to isolate the content before OCR. If you need a better input format for sharing or storage, finish with Image Convert.
Compared with upload-first OCR tools, FreeToolBox keeps screenshots, invoices, notes, and internal documents on your device. That matters when the text contains personal data, financial records, or private work material.

Frequently Asked Questions
What types of images work best for OCR?
OCR accuracy is best with high-resolution images (300 DPI or higher), good contrast between text and background, horizontal text orientation, and clear fonts. Handwriting, very small text, and low-quality photos may produce less accurate results.
Can I use this for receipts, invoices, or screenshots?
Yes. Those are some of the most common OCR use cases. The tool works well for receipts, invoice screenshots, scanned handouts, photographed notes, and interface screenshots where you need the text back in editable form.
Which image formats are supported?
The tool supports JPG, PNG, BMP, TIFF, and WebP image formats. For scanned documents, PNG or high-quality JPG gives the best recognition accuracy.
Can it recognize text in languages other than English?
Yes. Tesseract.js supports over 100 languages including Chinese (simplified and traditional), Japanese, Korean, Arabic, Spanish, French, German, and many more. Select your language before processing for best results.
Is my image uploaded to a server?
No. Tesseract.js runs entirely in your browser using WebAssembly. Your images are processed locally on your device and are never transmitted to any external server.
