8 best free OCR software I recommend 

As businesses and individuals digitize paper documents, automate data entry, and extract actionable insights from text in images and PDFs, the optical character recognition (OCR) market is expected to be worth around $13.12 billion in 2026.

And from what I’ve seen, “best” doesn’t always mean “paid.” Several free OCR software platforms I’ve evaluated offer robust text extraction capabilities — many free and open-source tools can convert scanned images, PDFs, and photos into editable, searchable text without incurring any costs.

The product list below contains real user reviews from the best free OCR software category page. It’s important to note that in the context of this list, vendors offering a free trial are also considered free.

To qualify for inclusion in this category, software must:

• Process digital images of various file types 
• Capture data from scanned PDFs and convert them into Word documents
• Identify and parse non-editable plain text and convert it into editable text
• Organize digital files either on-premise or in the  cloud 
• Offer engine compatibility across Mac, iPhone, Linux, Android, and Microsoft Windows

Pros and cons of DocuClipper: My review

What G2 users like about DocuClipper:

“I used DocuClipper for converting my clients’ bank statements and credit card statements to QuickBooks Online format files. It was very smooth and accurate, unlike other software that I have used for similar purposes. Overall, it is a very intuitive, user-friendly software. It is highly recommended that you are working with PDF statements. I haven’t explored it fully, but so far, it’s great.”

– DocuClipper Review, Javeria Z.

What G2 users dislike about DocuClipper:

“It would be great to have a pay-as-you-go plan for smaller businesses that don’t need it continuously but still need it for occasional projects. I don’t need it enough to warrant the cost of the annual plan. I needed DocuClipper for one project and had to pay the monthly fee and then cancel the subscription. I don’t need the program much, but when I do, it comes in very handy and saves me a ton of time.”

Rossum’s (formerly Elis) AI-assisted data extraction tool captures invoices. This platform can help accounting and bookkeeping professionals refine their workflows. Users can import PDFs or scans of invoices, and Rossum automatically extracts the relevant data into a structured format without the need for templates. Data can then be conveniently validated within the interface and exported for further processing using one of the tool’s software integrations, like NetSuite or QuickBooks Desktop Pro.

Pros and cons of Rossum: My perspective

What G2 users like about Rossum:

“The best thing about Rossum is the saved keystrokes. I mean, that’s the whole point of this. From a developer perspective, Rossum’s fairly open approach to allow for modification of the UI and how data is processed through Rossum was the true selling point. My company has very specific needs, and the ability to scale the UI up or down on the fly is incredible and easy.”

– Rossum Review, Connor S.

What G2 users dislike about Rossum:

“Rossum can be improved by learning how to read Excel documents, and sometimes the repeated behaviors we teach Rossum are ignored. Rossum is also limited to reading “straight” lines of data. If there were a way to tilt the grid to read orders that are misaligned, that would be appreciated.”

– Rossum Review, Steven S.
