PDF Tools: Docs & Editor

PDF Tools turns your phone into a document workshop. Scan paper to PDF, then open, read and edit the documents you already have — Word, Excel, PowerPoint, text and source files — without sending a single byte anywhere. Everything happens on your device. No account, no sign-in, no uploads. CREATE PDFs • Scan paper with automatic edge detection and perspective correction • Turn photos into multi-page PDFs — JPG, PNG, WebP and HEIC • Crop, rotate, reorder and filter pages before you export • Choose A4, Letter or fit-to-image, with orientation and margin control READ AND EDIT PDFs • Fast, high-resolution viewer with pinch zoom, single-page and continuous modes • Search inside the text of a PDF • Compress a PDF and see exactly how much you saved • Merge several PDFs in the order you choose • Sign with your finger, then move and resize the signature on the page • Add text anywhere, with independent items you can position individually • Lock a PDF with AES-256, or unlock one you have the password for WORD, EXCEL AND POWERPOINT • Open and edit .docx and .doc — formatted text, headings, lists, tables and images • Open and edit .xlsx and .xls — multiple sheets, number formats, merged cells and frozen panes • Open and edit .pptx and .ppt — slide view, thumbnails, speaker notes and a full-screen presentation mode • A spreadsheet formula engine with around forty functions that recalculates as you type, including SUM, AVERAGE, IF, VLOOKUP, SUMIF and COUNTIF Saving a .docx, .xlsx or .pptx rewrites only what you changed and copies the rest of the file byte for byte, so charts, themes, pivot tables and animations survive an edit untouched. TEXT AND SOURCE FILES • Plain text with encoding detection, preserved line endings, find and replace, word wrap and line numbers • Over thirty source and markup formats with syntax highlighting for their language: HTML, CSS, JavaScript, TypeScript, PHP, Python, Java, Kotlin, C, C++, C#, Go, Rust, Swift, Ruby, shell, SQL, JSON, YAML, TOML, Markdown and more • PHP and ASP.NET switch highlighting correctly between markup and the code embedded inside it • Code files open with monospace, line numbers and no wrapping, and carry indentation onto new lines EVERYTHING BECOMES A PDF Export any document to PDF in one tap — which also means the PDF tools work on all of them. Compress a spreadsheet, merge a Word document into a scan, or password-protect a presentation. PRIVATE BY DEFAULT • No account and no sign-in • Files are never uploaded; every conversion runs on your device • No analytics and no advertising in this release • The app declares no storage, media-library or camera permission — it uses Android's own permission-free photo picker and document picker OPEN FILES FROM ANYWHERE Open documents straight from the Files app, a share sheet or another app. Android decides which app handles a file type, so PDF Tools includes a screen that shows which types it can open and takes you to the system setting to choose it as your default. Requires Android 8.0 or newer.
