But what is Google OCR? The answer will begin with brief information about what is OCR.

OCR, the short term of Optical Character Recognition, refers to mechanical or electronic conversion of image-based files into machine-encoded text.

Google Drive, is the free cloud storage service offered by Google to store and share photos, videos, files and others in the cloud. It is more like your flash drive or disk to store files, but located in the cloud.

Google Docs, is the online platform in Google Drive helping users to manage files online, users can open, view, edit, share and sync the files in Google Docs. When dealing with scanned PDF or images, Google Docs will perform OCR on the files to make them editable and searchable. 

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.

6 Facts about Google Drive (Docs) OCR

To well understand how Google Drive OCR helps, here are 6 facts you need to know before using Google OCR.

1. Is Google Drive OCR Free?

Yes, 100% free.

Unlike other online OCR services, Google Drive OCR provides 100% free services, no matter how many files and how many pages you want to perform OCR in Google Drive, unless you have reach the storage limit of its free Google Drive service, you will need to pay to get more storage space for your scanned files. However, this rarely happens.

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

2. The Google OCR Supported Input & Output Formats

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 

That’s to say, you can use Google Drive OCR to save an image-based file as these 7 formats. Also, you can copy and paste the texts to a preferred text processor if you want to export as other formats.

3. How Many Languages Can Google Drive OCR Recognize?

Google Drive OCR supports reading more than 100 language. That is to say, only if you live on earch, 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 Supports 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:

google ocr handwriting

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;

5. You Cannot Perform Google Drive OCR on A Native PDF

tips: Native PDF means the PDF contains editable and searchable texts, not just a picture that its texts cannot be selected or searched.

This is quite important, since Google Drive OCR only works when you import an image-based file for conversion. It can just recognize if your files is scanned or a text image.

If you have uploaded a native PDF with some images, Google Docs won't recognize text from those images, it will omit all the images and only texts are displayed in the program:

So, in case that you want to do OCR an image in a native PDF, you’d better extract the image or save the PDF as image first, then upload for Google Drive OCR.
