Overview

Standing for optical character recognition, OCR is the mechanical or electronic conversion of images of typed, handwritten or printed text into machine-encoded text, according to Wikipedia. Does Google Drive have OCR? What is OCR in Google Drive? These are some of the frequently asked questions regarding Google Drive.

More than just a cloud storage service, Google Drive is integrated with a free, online office suite offered by Google. Google Docs is part of the suite and comes with a free OCR feature. So, yes, Google Drive has OCR. Google Drive OCR is also referred to or known as Google Docs OCR, but it’s not to be mistaken for Google Cloud Vision API OCR or Tesseract OCR.

Supported files

Import formats JPEG, PNG, GIF or PDF (multipage documents) files -
Export formats DOCX, ODT, RTF, PDF, TXT, HTML, EPUB -

Supported languages

Currently, Google Drive OCR supports 226 languages. It automatically detects the language of the uploaded image or document and provides multilingual spell checkers.

Handwriting recognition

In addition to supporting typed text, Google Drive can also recognize handwriting in images. It provides a free solution to digitize your handwritten notes, journals, etc. 

The performance and results will vary substantially due to how recognizable the handwritings are. For example, printed handwriting is easy for Google Drive OCR to read while cursive is not. Also, if your notes are written in pen instead of pencil, they will be easier for OCR software to handle.

Below are two examples.

How good is Google Drive OCR?

- The good

Google Drive (or Google Docs) is good at OCRing typed text content, be it in English or non-English, if the source document is in decent quality and properly scanned. It is also able to also provide satisfying results when it comes to neat, OCR friendly handwritings.

- The not-so-good

Google Drive OCR will retain (or try to retain) some formatting like italics, bold, font type or font size of the original document or handwriting. However, there is a big drawback. It won’t be able to detect tables, lists, columns, footnotes, layout, images, etc. If you try to use it to OCR a PDF with rich formatting, the result will be acceptable. It’s also a bad idea to digitize handwritten notes with drawings using Google Drive OCR.

Some tips to get better results

  • Make sure that your files are supported.
  • Make sure that the text is scanned horizontally. If not, rotate the image or PDF first.
  • The font should be at least 10 pixels high.
  • Use OCR-friendly fonts or typefaces if possible, such as Times New Roman.
  • The clearer the contrasts, the more likely your scanned files will be successfully OCRed.
  • Use neat, easily readable handwriting.
