Paper becomes PDF — without the cloud
Proof of address, ID card, receipt to archive: scanning personal documents is precisely the case where sending to a third-party cloud is most questionable. The scan tool assembles your photos into a clean PDF, in the browser.
Photograph each page flat, well lit, without blur.
Import the images — they’re assembled into PDF pages in your chosen order.
Export the PDF: ready to archive or send.
Improving the result afterwards
Deskew a tilted scan with the correction tool.
Grayscale to reduce size and even out pages.
Local OCR to make the content searchable and copyable.
The privacy angle
A mobile scan app typically syncs to a proprietary cloud before handing back your PDF. Here the chain is short: your photos → your browser → your file. Nothing else.
If you scan regularly
The camera is fine for an occasional document; for regular volumes, a dedicated scanner produces clean, straight pages back to back — the resulting PDF can then be processed with the same tools:
No store, no account: a two-click install, double-click to open a PDF, Android share target, and a full offline mode once you have visited the site online once.
Summarizing, translating and searching a PDF with models running inside the browser: what Chrome's built-in AI APIs and Transformers.js change for document privacy.
