Malayalam OCR Guide - Extract Text from Malayalam PDFs & Images Free

Malayalam has a reputation for complex typography: consonants combine into elaborate ligatures, vowel signs wrap around base characters, and special chillu letters represent final consonants. These features make Malayalam OCR one of the more challenging Indic scripts.

This guide explains how to extract accurate Malayalam text from scanned documents and images while preserving ligatures, chillus, and vowel signs.

Why Malayalam OCR Is Challenging

Malayalam script uses intricate ligatures, chillu forms, and vowel signs that must be segmented correctly.

Complex ligatures merge multiple consonants into a single glyph.
Chillu letters represent special final consonant forms.
Vowel signs attach above, below, before, and after consonants.
Rounded loops can merge in low-resolution scans.
Mixed Malayalam-English documents are common.
