Review before speech
Search page-aware sections and inspect the detected reading order before generation.
Private audio tool
Listen to your PDF without sending its words away.
Turn selectable PDF text into spoken audio while document text and generation remain on this device. Review page order, explicitly install the disclosed voice model, generate audio in manageable chunks, and download a WAV file. Scanned pages require OCR first, pronunciation may be imperfect, and complex reading order, tables, formulas, or unusual text can sound unnatural.
Audio workspace
Review the text, then generate real audio
PDF and text never upload
Choose a native-text PDF
Selectable PDF text becomes downloadable WAV audio. Image-only scans need OCR first and never produce empty audio.
Up to 64 MB and 100 pages. Nothing is sent to PdfEditorOnlineFree.
Verified on-device voice model
One-time 88.1 MB verified model download from a third-party model host. Apache-2.0 licensed files are cached for later offline use; PDF text is never sent with model requests. Review the source and licenses.
Desktop Chromium is recommended. Allow roughly 300 MB of free memory for the loaded model and short audio runs; mobile and long documents may hit available memory limits.

Reading-order preview
Page content's best reading order · page and chunk boundaries stay visible
Text and playback will appear here
Inspect selected pages before model setup. Complex columns, tables, and positioned labels may need OCR or manual cleanup.
Control the run
Choose verified voices and 0.5x-2x speed, then pause, cancel, or retry between bounded chunks.
Navigate playback
Seek the WAV, skip 15 seconds, jump by page or chunk, and follow honest chunk highlighting.
Download real bytes
Export a locally assembled mono PCM WAV only after every selected chunk succeeds.
Scans need OCR before audio
Image-only pages do not contain words for the voice model. PdfEditorOnlineFree identifies those pages, keeps generation disabled, and directs you to the OCR / Searchable PDF workflow rather than downloading an empty file.
Model assets are public; your text is private
Explicit setup downloads pinned Apache-2.0 voice assets from disclosed origins. After setup, PDF extraction, speech generation, playback, assembly, and download stay in this browser.
Continue your workflow
