Modoo File Converter

Modoo File Converter is an all-in-one Android utility that converts, compresses and extracts files entirely on your device, letting you avoid uploading sensitive documents to external servers. It handles image formats (JPG, PNG, WEBP, HEIC, GIF, TIFF, SVG, BMP), document formats (PDF, DOCX, XLSX, PPTX, TXT, CSV, Markdown, HTML), common archive types and Base64 encoding/decoding, all offline. Users who value privacy, need fast batch processing, or want flexible output options such as adjustable image quality or image-to-PDF merging will find this app useful for everyday file tasks.

Key Features

Modoo File Converter converts between JPG, PNG, WEBP, HEIC (Android 10+), GIF, TIFF, SVG and BMP with adjustable output quality and optional image-to-PDF merging. Document conversion supports PDF to images or text, DOCX to PDF or TXT, XLSX to CSV or TXT, PPTX to PDF or image formats, Markdown to PDF or HTML, and HTML to PDF or text. Archive tools include creating and extracting ZIP, 7Z, TAR, TAR.GZ and GZIP with batch compression and high-ratio 7Z support. A built-in Base64 encoder and decoder provides instant text-to-Base64 and Base64-to-text conversion as you type. Batch conversion, conversion history, dark mode and support for Korean and English improve everyday usability.

Advantages

Modoo File Converter performs all processing on-device so files never leave your phone and sensitive data remains private. The app works completely offline and does not require an internet connection for conversion tasks. Batch operations and conversion history help speed repetitive workflows, and a one-time purchase option removes ads; converted files are saved to the Downloads/ModooFileConverter folder for easy retrieval.

Disadvantages

HEIC to JPG or PNG conversion requires Android 10 or later, so older devices may not support that feature. There is no cloud-based conversion or automatic syncing to external services, which may be limiting for users who need cross-device access. The app displays ads until the one-time purchase is made to remove them.
