What does the online PDF reader do?
ReadLoudly's PDF reader opens a PDF in your browser and reads it aloud. Drop the file on the page and it is parsed into pages and sentences, the page images are rendered so the layout looks the way it did in Acrobat, and the text is queued for narration. Press play and a natural AI voice reads from the top of the current page while the sentence being spoken is highlighted on the page itself, not in a separate text box. Click any sentence to jump there, change the voice or speed mid-page, and the reader picks up from the same word.
It is built for PDFs that already contain selectable text: reports, textbooks, research papers, contracts, exported slides and ebooks saved as PDF. A PDF that is only a photograph of a page, such as a scan or a fax, has no text layer to read; that is what the Scanned PDF Reader is for, which runs OCR first. This page skips that step so a 300-page text PDF is ready to play in seconds rather than minutes.
Nothing is installed. The reader runs in Chrome, Safari, Firefox and Edge on desktop, iPad, iPhone and Android, and a guest can upload and listen without an account. Signing in adds a library: the PDF, your highlights, bookmarks and the exact sentence you stopped at are saved, so a chapter you started on a laptop resumes on your phone on the way home.
Three ways people use it
- Getting through a textbook chapter or paper — students and researchers upload the week's reading and listen at 1.25× to 1.5× while following the highlighted sentence, then use the built-in chat to ask what a section means or to pull out the key claims before a seminar
- Reviewing a long document without staring at it — professionals load a 60-page contract, policy or audit report and let it play through headphones on a commute, bookmarking the clauses that need a second look at a desk
- Reading with dyslexia, low vision or eye strain — hearing the text while seeing it highlighted takes the decoding load off, and the speed, voice and dark mode can be set once and kept for every file
Why listen instead of read?
A PDF fixes the layout, which is good for printing and bad for reading on a screen: two-column papers, small type and footnotes make the eye work harder than the content deserves. Having the reader speak the text while it highlights each sentence turns that fixed layout into something you can follow at a steady pace, and it frees your eyes for the figures and tables the voice cannot describe. Most people find they finish more of what they open, and remember more of it, when the text is heard as well as seen.

Frequently Asked Questions
Everything you need to know about Free PDF Reader.
Yes. Pages are rendered as they appear in the file — columns, figures, tables and page numbers all stay where they were — and the narration highlights sentences on top of that rendering. Only the reading order is interpreted, so a two-column page is read column by column rather than straight across.
A scanned PDF has no text layer, so this reader has nothing to speak. Open it with the Scanned PDF Reader instead, which runs OCR on each page first and then reads the recognised text aloud in 40+ languages.
No page limit and no daily cap on the free browser voices. The only free-plan limit is the upload size, 50 MB per file. Premium voices are metered by monthly voice credits on the paid plans.
Yes. For a passage you have copied, an email or your own notes, use the free text to speech tool; it is the same reader with a text box in front of it and no file to upload.

Yes — PDF is fully supported on this page, and it is one of 24 formats ReadLoudly reads aloud: documents (PDF, DOCX, ODT, RTF), ebooks (EPUB, MOBI, AZW, FB2, CHM, LRF, LIT, PDB, RB), text and web files (TXT, HTML), comics (CBR, CBZ), and images (via OCR) (JPG, PNG, GIF, BMP, WEBP, TIFF, SVG).

It is parsed to extract its text, then removed from the processing servers. ReadLoudly does not train models on your files, does not share them with third parties, and does not make them visible to anyone else. Signed-in users can choose to keep a PDF file in their own private library; a guest upload is discarded when the session ends.
Every format gets its own reader page rather than being funnelled into one generic uploader, so nothing loses its format-specific handling. Nearest neighbours to PDF among ReadLoudly's documents: PDF, DOCX, ODT, RTF. The Tools page lists all of them.
