PDF Toolbox: Offline PDF Tools Live

PDF Toolbox puts more than 100 PDF tools in one desktop window on Android laptops. Pick a tool in the sidebar, add your file, and the tool runs on your device. There is no server, and the app has no permission to use the internet, so your files never leave your device. Organize Merge, split, reorder, rotate, delete and extract pages. The PDF Multi Tool does all of it on one grid of pages. Edit Click a paragraph and change its text. Annotate, highlight, redact, sign, fill in and create forms, crop, and add watermarks, page numbers, stamps and bookmarks. Convert Office documents (.docx, .xlsx, .pptx) and OpenDocument files to PDF, with an office suite that runs inside the app. PDF to documents, spreadsheets, text, Markdown and images. Images, EPUB, email and Markdown to PDF, and PDF/A for archiving. Clean up Make scanned PDFs searchable with text recognition (OCR), compress, remove blank pages, straighten scans, encrypt and decrypt, change permissions and remove metadata. Workflows Chain tools into a pipeline of your own with the Workflow Builder. Made for laptops Every tool is one click away in the sidebar, with your recent tools at the top. Ctrl+K searches the tools, and Ctrl+B folds the sidebar into a row of icons for more room. Open a PDF with PDF Toolbox from the Files app, or share files to it, and the next tool you open takes them. Results are saved to your Download folder. Private No internet permission, no accounts, no ads, no analytics and no crash reports. PDF Toolbox asks for no permissions: you choose each file it opens, and it saves its results to your Download folder. Limits Text recognition reads English. Trusted timestamps and certificate checks for digital signatures need the internet, so they don't work. Very large files can run out of memory. Converting office documents needs an up-to-date Android System WebView. The app takes about 200 MB, because its engines come with it.
