So, Google OCR, is also called as Google Drive OCR or Google Docs OCR, refers to OCR processed by Google Docs, the web-based office suite program in Google Drive, where Google allows users to store and synch files, helping users convert image-based files to editable formats. 

While, the Google OCR Tesseract, is an open-source OCR engine sponsored by Google, and it is believed that the Google Drive/Docs OCR uses Google Tesseract to offer online OCR services.

Notes: Also, there is Google Cloud Vision OCR, it is API offering pre-trained machine learning models to detect objects, faces, read printed and handwritten text from images, it is for developers. For general users like us, it is easier for us to use Google Drive OCR on our PDFs and images.

However, this rarely happens.

Even its API, the Google Tesseract is widely used by software developers as open source to create their owns.

2. What Format Does Google Drive OCR Support?

Supported Input---Scanned PDF, Images (JPG, GIF, PNG, BMP), Handwriting files.

In fact, Google Docs supports to upload files in various formats, but its OCR only works when you importing image-based files, such as scanned PDF, JPG, GIF, PNG BMP and handwriting files. As for other image formats, such as TIFF or PSD, Google Docs OCR doesn’t support.

Support Output---Docx, ODT, RTF, PDF, TXT, HTML, ePub

3. How Many Languages Can Google Drive OCR Recognize?

Google Drive OCR supports reading more than 100 language, including English, Chinese, Japanese, German, Spanish, French, Arabic, Dutch, Greek, Hebrew, Hindi, Italian, etc. That is to say, only if you live on earth, it is much likely that your files can be recognized by Google OCR.

But according to users, the accuracy on different languages differs. If you are doing OCR on a English file with Google OCR, the accuracy is highly guaranteed and there is no need to manually adjust heavily; but if you are working on Chinese or Japanese, the accuracy is relatively lower and you will need to double check the OCR results carefully.

4. Google Drive OCR Handwriting Files

It is really a good news to know that Google Drive OCR comes to support handwriting files. However, it seems that improvements on performing OCR in Google Drive are needed.

I uploaded a handwritten file onto Google drive and open with Google Docs, the OCR result is displayed as following:

As you can see, though Google Drive OCR can recognize most of the words, it puts them in the wrong place and there is no formatting retained. To use Google Drive OCR on handwritten files to your benefit, there are some tips:

  • Make the handwritten files flat and clean;
  • Make sure the handwritten files are neatly lettered;

So, Google OCR is the safest online free OCR service protecting our files saved in Google account. It allows users to edit the scanned documents after OCR, also exports as different output formats. However, you will notice that it doesn’t do as excellently as other desktop OCR programs on formatting preserving, there are incorrect headline fonts, blank tables, discontinued sentences, big gaps between paragraphs, etc.
