- Fill the frame with the page.
- Direct Answer
- There is no single most accurate OCR engine for every document. Accuracy depends on scan quality, resolution, language and script, and we have not published a head-to-head benchmark. Test each engine on your own documents.
How OCR Engines Are Evaluated
To evaluate OCR accuracy, test suites measure Character Error Rate (CER) and Word Error Rate (WER) across diverse document types: - Clean 300 DPI English printed text - Scanned multi-column financial tables - Non-Latin cursive scripts (Arabic, Urdu, Farsi) - Low-contrast mobile photo snapshots
Testing OCR Engines Yourself
Run the same sample pages through each engine and compare the output character by character. Pay most attention to numbers, proper nouns, non-Latin scripts and multi-column pages.
How FastOCR Fits
FastOCR reads text with cloud OCR and neural recognition models, and offers optional AI Polish, which uses a language model to fix common misreads on single images. Results still depend on the scan, so check the output.
Frequently Asked Questions
What is the most accurate OCR for Arabic and Urdu script?
We have not published a benchmark. FastOCR reads printed Arabic and Urdu, but accuracy depends on the font, scan quality and diacritics, so test your own documents.
Does scan resolution affect accuracy?
Yes. Scanning at 300 DPI or higher gives noticeably better results than low-resolution 72 DPI images.
