Make Every Document
Readable
ConvertDys transforms PDFs with the OpenDyslexic font, making reading easier for the 780 million people worldwide living with dyslexia.
The Challenge of Dyslexia
Standard documents create daily barriers for millions of readers. Letters swap, lines blur, and comprehension suffers.
Letters Swap & Rotate
Standard fonts make b/d, p/q, and similar letters nearly indistinguishable, causing constant reading interruptions and frustration.
Dense Documents
PDFs with tight spacing and small fonts create visual crowding, making it exhausting to track lines and maintain reading flow.
Lost Productivity
Students and professionals spend 2-3 times longer reading standard documents, losing hours every day to inaccessible formatting.
