Make an audiobook from any PDF: ebooks, study notes, reports or articles. VoidConvert reads the text aloud with natural-sounding Piper voices (English, Hindi, Japanese) and gives you one MP3 you can play on your phone, in the car or offline. Scanned PDFs and photos of notes are read with OCR first. EPUB, Word, text and RTF files work too.

Text, tables and images are kept in place so you can edit contracts, CVs and reports without retyping. Scanned PDFs are detected automatically and run through OCR (English, Hindi, Japanese).
Open PDF to Word Converter →Shrink big PDFs so they fit email and upload limits. Pick light, balanced or strong compression; images inside the PDF are resampled and the text stays sharp and selectable. You see the size before and after. JPG and PNG photos can be compressed too.
