The Best Free Online OCR Tools of 2026
I've tested the best online free OCR tools, and here are my recommendations.
After testing a variety of online OCR tools, I can recommend some good ones for converting scanned documents to editable text. Here's my verdict on which tools are best for English versus multilingual (Arabic, Urdu, Farsi) documents.
Overall Verdict for 2026
I tested ten different online OCR tools, using a simple English document, a scanned Urdu page, and a scanned Arabic document as my test set. The main workflows I used were image-to-text and PDF-to-text. I found that PDF24 and iLovePDF were the best free options for English PDFs, while FastOCR and Google Drive OCR were the only reliable free choices for Arabic, Urdu, and Farsi.
No Registration or Installation Required
A few of these tools don't require registration or installation, which is convenient. PDF24 doesn't require any kind of account at all — just upload your file and click "Convert". OCR.space requires no registration, but you'll need an internet connection to use it. iLovePDF is browser-based, so there's no need to install anything either. However, FastOCR does require a free account in order to process PDF files. For image OCR, FastOCR allows unlimited processing without requiring registration.
File Size and Daily Usage Limits
All of these tools impose limits on the size of the files they'll process and how many times per day you can use them. OCR.space has a limit of 5 MB per document, Soda PDF has a limit of 3 MB or less with a daily limit of two files, and pdfFiller has a limit of up to 100 MB for PDFs.
Document Privacy and Data Retention
Some of these tools handle uploaded documents differently when it comes to privacy and post-processing data retention. OCR.space deletes both the original file and the extracted text immediately after processing, and claims to be fully GDPR compliant. Soda PDF deletes the files from their servers within 24 hours, and claims that the files remain private.
PDF24 Offers Broadest Free Feature Set
PDF24 offers the broadest free feature set among the no-registration tools. In addition to OCR, it allows you to save the output as a PDF/A, remove artifacts and noise, deskew pages, set meta information, and join results into a single output file. All of these operations are done entirely in the cloud, so you won't have to use any local resources.
Google Drive OCR Is the Best Free Multilingual OCR Option
If you're looking for a way to do non-Latin script OCR (like Arabic, Hebrew, etc.) for free, then Google Drive OCR is probably the best option. Simply upload your PDF or image to Google Drive, right-click it, and choose to open it with Google Docs. This method handles Arabic, Hebrew, and other non-Latin scripts better than most dedicated OCR tools, making it the best free multilingual OCR option available.
Matching Tool Choice to Use Case
When choosing between these tools, it's important to consider your specific needs. If you're doing batch processing, then professional or business use with large volumes of documents is probably the right choice. On the other hand, if you're working in the field and need mobility, then one of the mobile-compatible online tools might be more suitable. Finally, if you're dealing with documents in languages other than English, you should choose a tool that supports those languages.
