PDF Summarizer

Collect key sentences, with optional on-device AI summaries.

Local processing

The default mode selects source sentences using word frequency; it is not a generative summary. Browser AI needs a supported device and can omit or misstate information.

Source tools work on this device. AI needs either the server model connected or a browser with on-device AI support.

PDF Summarizer FAQs

Will the summary capture every important point?

No. Automatic sentence selection and AI can miss context. Use the result as a reading aid and review the original document. The server AI mode does not need browser-native AI; it requires the site’s model connection.

Are my documents uploaded?

Local PDF tools process documents in your browser. Choosing a file alone does not upload it. Server conversion sends the chosen file only after you confirm; server AI sends extracted text only after consent. Download your output before closing the page; there is no cloud document library.

Are my PDFs encrypted?

The website uses HTTPS to encrypt the connection. Local processing does not automatically password-encrypt your input or downloaded PDF. No website can guarantee 100% security; use a trusted device and keep your original files.

How do I save a PDF on an iPhone?

After creating the result, use Save / Share and choose Save to Files. If a download opens a preview, use the browser’s Share control to save a copy.
