Open PDF Reader with Font Size Adjuster → free, no sign-inMost PDF readers are not designed with accessibility in mind. Text size is fixed at whatever the document author chose, which is often too small for comfortable reading — particularly on a laptop screen or for anyone with a visual impairment. The PDF Reader with Font Size Adjuster lets you set the text size yourself, and adds text-to-speech that reads the document aloud while highlighting the text on screen so you can follow along.
People with dyslexia, visual impairments, or anyone who simply prefers to listen to long documents rather than read them will find this genuinely useful. It's also helpful for reviewing documents hands-free.

No server uploads. The read-aloud highlights text in sync with the speech, making it easier to follow the content and return to specific sections.
