LibreOffice is a free and open-source office suite with tools for word processing, spreadsheet creation, slideshows, diagrams, and more. Many people around the world use it. Because it is open-source, volunteers develop it, and anyone can help improve it.
Optical Character Recognition, or OCR, is a technology. It turns printed or handwritten papers into text you can edit on a computer. This is very helpful for saving time and making old documents easy to use and share. Now, let's look at how to use LibreOffice OCR.
In this article
Part 1. How to Use OCR in LibreOffice
To start with LibreOffice, you first need to download and install it. Visit the LibreOffice website and click on the download link. Choose the version that matches your computer system, like Windows or Mac, and follow the prompts to install it. Once installed, you can start using its many features.
LibreOffice has several parts. The most used are Writer for word processing, Calc for spreadsheets, and Impress for presentations. While LibreOffice doesn't have its own OCR feature, it works well with text files created by OCR tools.
For OCR, you'll need a separate program to scan your documents and convert them into text. After scanning, you can open and edit these text files with LibreOffice Writer. This setup lets you easily adjust the converted documents, making it simple to work with the text just like any other document in LibreOffice.
Step-by-Step Guide to OCR a PDF in LibreOffice
To work with a PDF in LibreOffice and use OCR (Optical Character Recognition), you first need to handle it in LibreOffice Draw. Here's a simple guide:
Step1
Start by opening LibreOffice. Open LibreOffice and click on “File” in the top menu. Select “Open” and find your PDF file. Once you open it, Draw will display the PDF content.
Since LibreOffice doesn’t have an OCR feature, you need to use an external OCR tool to convert the text in your PDF. One popular choice is a free online OCR service. Upload your PDF to the OCR service, and it will convert the images and text into editable text.
Step2
After converting, download the text file from the OCR service. Then, open LibreOffice Writer, click “File,” and select “Open.”
Step3
Find the text file you downloaded and open it in Writer. Now, you can edit the text as needed.
Step4
After editing, save your work as an ODT file. This is the primary format for LibreOffice Writer. Always work on this file for future edits.
Step5
When satisfied with your document, you can export it as a PDF again. Click "File" > "Export" > "Exportas PDF" and select "HybridPDF." This will save your new document as a PDF.
This method keeps your documents easy to edit and share in the future.
