ClearPDF

ClearPDF is an Android document toolkit for reading and annotating PDFs, managing PDF pages, scanning paper documents, and opening common Office and image files. The source is licensed under MIT. Most file operations run on-device. The FOSS build uses network for its optional Office engine and URL-to-PDF features; Google Play services may provide scanner and background-removal components.

What you can do - Read and work with PDFs Read with continuous scrolling, pinch-to-zoom, page navigation, and in-document search. - Select and copy text; run on-device OCR for image-only pages. Add highlights, underlines, strikethroughs, ink, shapes, arrows, text notes, and signatures. - Fill PDF forms, flatten form fields, and export an annotated copy. - Organize, rotate, delete, or extract pages; merge and split files. - Compress, encrypt, or decrypt PDFs; add page numbers or watermarks; export pages as images; extract text; create PDFs from text or images.

Open Office and text documents - Open PDF, DOC/DOCX, XLS/XLSX, PPT/PPTX, ODT/ODS/ODP, RTF, CSV, and TXT files. Rendering depends on the format and renderer. The optional LibreOffice-based engine can improve rendering for supported Office formats. - The spreadsheet editor can edit and save XLSX workbooks. Word and PowerPoint files are opened for viewing; ClearPDF does not rewrite their original text layout. You can annotate the rendered document and export it as a PDF.

Edit images and scan paper - Crop, rotate, straighten, and perspective-correct images. - Adjust colour and tone, apply filters, draw, add text or watermarks, and resize. - Remove image backgrounds on supported devices; Google Play services may provide the segmentation model. - Scan multi-page documents, adjust the results, and save them as PDF. Scanning is provided by Google Play services and depends on its availability on the device. - Create PDFs from local content or a web address - Create a PDF from images, text, or local HTML. The FOSS build can also convert a web address; this requests that site and its page resources. Local HTML conversion works without loading a website.
