Guide

How to Extract Text from an Image Online

Follow this quick 4-step guide to convert any image to text using our free online OCR tool.

01

Launch the OCR Tool

The OCR tool is loaded at the top of this page — simply upload an image to start extracting text instantly, no installation required.

02

Upload an Image or PDF

Drag and drop or select any image file (JPG, PNG, BMP, screenshot) or scanned PDF containing the text you want to extract.

03

Let OCR Detect the Text

The unified recognition model handles supported languages automatically, including Chinese, English, Japanese, Korean, and mixed printed text.

04

Review and Copy the Text

Check names, numbers, and punctuation, then copy the editable result to your clipboard for use in another application.

Review OCR Results Before Reuse

OCR turns pixels into editable characters, but recognition is not a guarantee of correctness. Blur, unusual fonts, complex tables, handwriting, and low contrast can introduce mistakes.

Always verify names, account numbers, dates, legal clauses, medical details, code, and other high-impact text against the original document.
