Questions about PDFs.

How do I make a PDF read aloud for free?

Adobe Acrobat Reader and Microsoft Edge read PDFs aloud, and so does Speak selection on a Mac (Option + Esc). LoudFlow is free too, 1,000 words a day, in any PDF app: select text and press Ctrl + Space.

Can it read a long PDF?

Yes. Select the next page and press Ctrl + Alt + Space. It reads on.

What about a scanned PDF?

Only if you can select its text. A scan that is just a picture can’t be read.

Does it work on Windows and Mac?

Yes. Windows, and Mac with macOS 14 or later (Intel Macs: 13.4 or later). The user guide shows each step.

Who sees my PDFs?

LoudFlow never sends your texts to us or to anyone else.

The long PDF, read to you.
