LibreDoc Reader is a private, local-first document toolbox. READ AND ORGANIZE - Open PDFs, text files, images, office documents, presentations, spreadsheets, EPUB books, and other formats supported by iOS Quick Look. - Search your local library and recognized text. - Import explicitly from Files, Photos, the camera scanner, or the clipboard. EDIT AND ANNOTATE - Highlight, add notes, rotate, and remove PDF pages. - Try one recognized PDF text change free, then save and open the edited copy automatically. - With PDF Editor or Full Pro, replace recognized visible text in ordinary and scanned PDFs and save a new flattened copy. - Edit DOCX, ODT, RTF, and a broad range of plain/source-text formats directly. Legacy DOC changes are saved safely to a new DOCX copy. - Export a copy whenever you choose. SCAN AND CONVERT - Scan paper pages with automatic edge detection. - Run automatic OCR on the device across recognition languages supported by iOS, with an additional Belarusian Cyrillic fallback. - Convert supported content locally between PDF, TXT, DOCX, RTF, HTML, CSV, JPEG, and PNG. - Extract text from DOCX, XLSX, PPTX, unencrypted EPUB, PDFs, and images; Office/EPUB β€œtext layout” exports do not preserve complex layout, formulas, charts, animation, macros, or embedded objects. - Export the first supported PDF page as JPEG or PNG. PRIVATE BY DEFAULT - No account is required. - Documents remain on the device unless you explicitly share or export them. - Document content is never sent to the advertising provider. LibreDoc does not promise to open or edit every possible file. Availability depends on the format, file integrity, encryption or DRM, and capabilities provided by the installed iOS version. See the in-app Format Support page for the exact matrix.
