PDF Editor - Doc Viewer

PDF Editor & Doc Viewer is an Android app for opening PDFs, adding quick markup edits, and previewing HWP/HWPX/DOCX/XLSX/PPTX files locally on your phone.

Main features:

- Open PDF files and reopen recent documents
- Preview HWP/HWPX/DOCX/XLSX/PPTX files locally
- Show PDF conversion guidance for legacy DOC/XLS/PPT and ODF-family documents
- Add pen, highlighter, and text annotations
- Add handwritten signatures and images
- Move and resize inserted images or signatures
- Rotate, delete, reorder, and merge PDF pages
- Save edited documents as new PDF copies or share them with Android's share sheet
- Add an open password to normal, shared, or secure redaction PDF copies
- Save secure redaction copies as image-based PDFs
- Choose system, light, or dark mode in Settings
- Receive in-app update prompts for Google Play distributed versions

Documents are processed on the device by default. The app does not send PDF files or personal information to a developer server.
HWP/HWPX/DOCX/XLSX/PPTX preview is a file-format interoperability feature. Layout may differ from the original editor, and this app is not affiliated with or endorsed by Hancom or Microsoft.
The app does not bypass password/DRM protections or run document macros.
Standard copy saving covers redactions with white rectangles, so use Secure Redaction Copy Save when you need sensitive content removed from the exported result.
If you open a password-protected PDF and save without password protection, the new copy will open without a password.
