The size and variety of a comic library are crucial factors that determine the richness and diversity of content available to users. Perfect Viewer excels in this aspect by supporting an extensive range of file formats including image files such as JPEG, PNG, GIF, BMP, WebP, and TIFF, as well as archive files like CBZ/ZIP, CBR/RAR, 7Z/CB7, LZH, and CBT/TAR.

This vast compatibility and access to various sources make Perfect Viewer a powerful tool for comic enthusiasts looking to build and enjoy a comprehensive and diverse library.

Content authenticity and proper licensing are essential considerations for any digital comic viewer, ensuring that users have access to legitimate and high-quality content. Perfect Viewer addresses these concerns by providing features that support the viewing of properly licensed and authenticated content. While the app itself does not directly manage content licensing, its capability to integrate with various file sources allows users to access comics and ebooks that they have legally acquired. The support for DRM-free EPUB, HTML, and TXT files enables users to load and read ebooks that are often purchased from reputable online bookstores. Furthermore, the requirement of specific permissions for accessing cloud storage services like Google Drive underscores the app's commitment to ensuring that user data and content sources are handled responsibly. By focusing on DRM-free formats and facilitating access to legally obtained content through verified sources, Perfect Viewer provides a platform where users can confidently engage with their digital comic collections, knowing that they are respecting copyright laws and supporting content creators through legitimate means.
