OCR vs Image Translation: What's the Difference?
By ScanText Team · 4 min read · 2026-09-22
OCR and image translation are related but distinct tasks. OCR (optical character recognition) extracts text that is already in the image's language and produces editable text in that same language. Image translation does OCR first, then translates the extracted text into a different language.
OCR: Image to text
OCR reads text from an image and outputs it as editable text in the same language. For example, an image containing English text becomes English text you can copy and paste. A photo of a French sign becomes French text.
- Output language matches the source image language
- Output is editable, searchable text
- No language change occurs
Image translation: Image to translated text
Image translation performs OCR to read the source text, then translates it into your chosen target language. For example, an image containing Urdu text can be translated to English. The result is text in the target language, not the source language.
- Output language differs from the source image language
- Two-step process: OCR then translation
- Result is editable text in the target language
When to use each
- Use OCR (image to text) when you need the text in the same language — for editing, archiving, searching, or copying from screenshots.
- Use image translation when you need the text in a different language — for understanding signs, menus, documents, or screenshots in foreign languages.
- Use OCR first when the target language matches the source and you need to preserve every character exactly.
- Use image translation when the target language differs from the source and you need a human-readable translation.
