Análisis de la app PDF Reader: AI Document Tools para 8 de noviembre

The complete offline PDF editor. Read, edit, sign, scan, convert, merge and protect your documents entirely on your phone — no account, no subscription, and nothing is ever uploaded to a server. Most PDF tools send your files away for processing. This one doesn't. Every conversion, every scan, every page you sign happens on your device — which is why the whole app keeps working offline, on a plane, or with no signal at all. READ A fast, quiet PDF reader. Open PDFs with smooth continuous scrolling and pinch-to-zoom. Search for text inside a document and jump straight to the result. Night mode inverts the page for comfortable reading in the dark. Bookmark any page, and the app remembers where you stopped so you can pick the document up later. Auto-scroll moves the page at a speed you set, for hands-free reading. EDIT & SIGN Draw freehand, highlight, underline or strike through text, and add your own notes anywhere on the page. Sign documents with your finger and place the signature exactly where it belongs. Your marks are written into the PDF itself, so they are still there when the file is opened anywhere else. The original file is never overwritten — every edit is saved as a new copy. SCAN & RECOGNIZE TEXT Scan paper documents with the camera. Edges are detected automatically and the page is straightened for you. Text recognition then reads the words from the scan and writes them back into the PDF as a real text layer, so the scanned document becomes searchable — while the page still looks exactly like the scan. CONVERT Turn PDF pages into images, or build a PDF from photos already on your phone. Convert a PDF to a Word document, or a Word document to a PDF. Every converter here works offline. Because the work is done on the device, a private contract or a medical letter never leaves your hands. ORGANIZE & PROTECT Merge several PDFs into a single file, in exactly the order you choose. Split the pages you need into separate files. Lock a document with a password using standard PDF encryption, and unlock documents you have the password for. ON-DEVICE SUMMARY & TRANSLATION Get the gist of a long document in seconds. The summary is built from the document's own sentences, each one shown with the page it came from, so you can verify anything before you trust it — nothing is made up, and nothing is sent anywhere. Translate documents into Spanish, Korean, Hindi, Portuguese, Japanese and more, using language packs that download once and then work offline. MANAGE YOUR FILES Browse everything in one place, filtered by PDF, Word, Excel or PowerPoint. Star the documents you use all the time. Sort by name, date or size. Rename, delete or share straight from the list, and print from the reader. WORTH KNOWING BEFORE YOU START PDF and Word conversion carries over the text and paragraph breaks, not the original layout, images or tables — there is no layout engine on a phone, which is why other apps do this on a server. Text recognition and document scanning use Google Play services and work with Latin script. Translation downloads a language pack of roughly 30 MB the first time you use each language; after that it works fully offline. PRIVACY This is an offline PDF reader and editor. There is no account and no sign-up. Your documents are never uploaded, and the app only sees the folder you point it at. You can revoke that access at any time in Android settings.
