What Is OCR?
OCR stands for Optical Character Recognition — a technology that analyses images and identifies text characters within them. It allows you to take a photograph of a document, screenshot, or scanned page and convert the visible text into editable, searchable text that you can copy, edit, and paste.
When You Need OCR
- Photographed a menu, notice, or sign and want to copy the text
- Received a scanned document that you need to edit
- Have a PDF from scanning that is not searchable (Ctrl+F doesn't work)
- Need to extract text from a certificate or official document
- Want to digitize old printed documents for archiving
- Received an image-based PDF that you need to convert to Word
Free OCR Methods
Method 1: Google Drive (Best for Scanned PDFs)
- Upload your image or PDF to Google Drive
- Right-click the file → Open with → Google Docs
- Google automatically applies OCR — extracted text appears in the document
- Edit and export as needed
Method 2: Google Lens (Best for Phone Photos)
- Take a photo of the text
- Open Google Lens (available in Google app and Google Photos)
- Tap "Text" mode
- Select all text and copy
Method 3: Microsoft OneNote
- Insert the image into a OneNote page
- Right-click the image → Copy Text From Picture
- Paste the extracted text anywhere
OCR Accuracy Tips
- Higher image resolution = better accuracy (300 DPI minimum for printed text)
- Clear contrast between text and background improves recognition significantly
- Handwritten text is much harder for OCR — accuracy is lower than printed text
- Tilted or perspective-distorted images reduce accuracy — straighten before OCR
After OCR: Converting to PDF
Once you have the extracted text in a Word document or Google Doc, convert to PDF using iloveconvert.in for a clean, shareable version of the document with fully searchable text.
