Bionic reading for PDFs — without uploading the file

Updated 2026

Search for a bionic PDF converter and you will find websites that ask you to upload the document and hand you back a re-typeset copy. That is fine for a public paper. It is not fine for a contract, a medical letter, an unpublished manuscript or anything under NDA — and it produces a second file you now have to manage.

The local way

  1. Open QuickReadMac and drop the PDF onto the window — or right-click the file in Finder and choose Read File with QuickReadMac.
  2. The text is extracted on your Mac with Apple's own PDFKit. Nothing is uploaded and no copy is created.
  3. Pick Bionic mode. Every word gets its bold anchor; the page stays fully readable.
  4. Adjust fixation strength in settings, or turn on text-to-speech and have it read aloud while the words highlight.

What it can and cannot extract

Text-based PDFs — the overwhelming majority of papers, contracts, manuals and ebooks — extract cleanly, including multi-column layouts. A PDF that is really a scan (a photograph of a page with no text layer) has no text to extract; macOS Preview can often recognise the text in one, and once it can be selected, ⌃⌘R will read it.

It also handles the rest of your reading

ePub, Word (.docx), Markdown, plain text, and any selection in any app go through the same pipeline, so you are not switching tools when the format changes. Your position in each document is remembered, so a 400-page PDF picks up where you left off.

Questions

Does the PDF get uploaded anywhere?

No. Extraction uses Apple's PDFKit on your Mac. QuickReadMac makes no network request with your document — the only requests it ever makes are an update check and licence validation.

Do I get a converted PDF file back?

No, and deliberately: instead of producing a second file, the app renders the text with fixation anchors in its own reader, so the original stays untouched.

What about scanned PDFs?

A scan without a text layer has nothing to extract. Open it in Preview first — macOS can usually recognise the text — then select it and press ⌃⌘R.
