10月1日 的 Universal File Opener & Editor 應用程式分析

Open PDF, Word, Excel, PowerPoint, images, ebooks, archives, code, media, and 375 file extensions offline. Universal File Opener has no INTERNET permission, so the app itself cannot upload your files or send analytics. No ads. No account. No sign-in. Reading is free forever: no file limit and no time limit. Useful tools are free too. Fill and sign PDFs, read documents aloud, scan paper to PDF, run OCR, extract archives, recover damaged files, remove hidden metadata, and create or save common text, code, web, and data files. FREE FOR EVERYDAY USE • Open PDF, DOCX, XLSX, PPTX, ODT, ODS, ODP, EPUB, MOBI, ZIP, RAR, 7Z, images, audio, video, source code, databases, fonts, certificates, and more. • Search documents, copy text, inspect properties and hidden data, browse Office structure, view evaluated spreadsheet formulas, and play local media. • Create and save TXT, Markdown, CSV, JSON, XML, HTML, CSS, JavaScript, Python, shell scripts, and other common files without Pro. • Edit and save images free: crop, straighten, resize or extend the canvas, adjust light and color, apply filters, draw, add text and shapes, blur or pixelate areas, add borders and watermarks, compress, convert formats, and remove image metadata. • No opening quota, ads, account, watermark, or wait screen. DESKTOP-CLASS EDITING, THREE PRO OPTIONS Every editor is free to try on your own files. Pro saves your edits, exports and new files in Pro formats. Pick a monthly plan, a yearly plan, or one lifetime purchase; the monthly plan starts with a free trial for eligible new subscribers, and both plans can be cancelled anytime in Google Play. This Pro purchase is for Android only; Windows, macOS, iOS, and Linux each have separate purchases. • PDF: edit existing text, fill forms, sign, draw, highlight, stamp, redact, add text and images, crop, compress, reorder or combine pages, add page numbers and watermarks, and protect a copy with a password. • Word and PowerPoint: edit text, formatting, styles, lists, links, comments, images, tables, headers, footers, page setup, slide order, shapes, notes, and backgrounds. • Excel: edit cells, formulas, formatting, rows, columns, sheets, filters, fills, comments, links, dropdowns, conditional formatting, and charts. • Text, code, CSV, hex, and SQLite: edit text and grids, patch bytes, and update database rows. Editing runs on your device. Writable files can save back through Android's file access system. For read-only shares, save an editable copy. PRIVATE BY DESIGN • No INTERNET permission means no in-app uploads, telemetry, analytics, or tracking SDKs. Share, Open with, Print, Read aloud, and Android's file picker use the app or storage provider you choose. A cloud-backed provider may sync files under its own privacy practices. • Optional diagnostics and request emails are created only when you choose. They omit file contents, names, paths, hashes, clipboard text and payment details unless you attach a file. • Interface languages: English, Latin American Spanish, French, German, Hindi and Indonesian. HONEST FORMAT SUPPORT Modern PDF and Office editing is progressively richer and preserves untouched package parts; it is not a clone of desktop Office. Legacy XLS opens as a read-only grid. DOC and PPT convert in one tap to an editable copy. Single-volume RAR4 and RAR5 archives, including passwords, and ISO 9660/Joliet images support browsing and extraction within size limits. Multi-volume archives, UDF-only images, DRM-protected ebooks, and formats such as CAB, DMG, LHA, and LZH remain unsupported. Unknown files can open as text or hex when possible.
