Q: How can I compress a file before converting it?
A: You can compress a file by using tools like 7zip or WinRAR on your computer before uploading it to our platform. This helps reduce the file size for quicker conversions.

A: If the archive is corrupt, the conversion might fail. We recommend checking your file for corruption before uploading it to ensure a smooth conversion process.
Q: What if my archive file is in an unsupported format?

Q: What is archive conversion?

What is CHM (Compiled HTML Help)?
CHM (Compiled HTML Help) is a format used for help files and documentation, typically in Windows environments. It is a compressed archive that contains HTML pages, images, and other resources that are displayed through a special viewer, usually for software documentation and help systems.
CHM files are commonly used for offline help documentation in software applications, providing easy navigation with a table of contents, search functionality, and index.
How to open CHM?
CHM files can be opened with the built-in Windows CHM viewer, known as 'HTML Help Viewer.' Simply double-click the CHM file, and it will open in the viewer.
For macOS and Linux users, third-party software like 'CHM Viewer' for macOS or 'xCHM' for Linux can be used to view CHM files.
In case the CHM file is not opening, ensure that the file is not blocked by your system’s security settings.

What is LRF (Portable Reader File)?
LRF (Portable Reader File) is a proprietary ebook format developed by Sony for its Sony Reader devices. Based on the Broad Band eBook (BBeB) format, LRF files store formatted text, images, and metadata in a compact binary structure optimized for Sony's e-ink displays.
LRF files offer features like fixed page layouts, embedded fonts, and high-quality image display. Though Sony has since transitioned to more standard formats like EPUB, a significant library of legacy content exists in LRF format, particularly Japanese literature and manga published for early Sony Reader models. Supported extension is .lrf.
How to open LRF?
LRF files can be opened natively on Sony Reader devices, including the PRS-500, PRS-505, and PRS-700 models. For other platforms, dedicated software is limited since Sony discontinued support for this proprietary format.
Currently, the most effective way to access LRF content is through conversion. Ebook management software like Calibre can convert LRF files to more widely supported formats like EPUB or PDF. Some specialized applications like LibreOffice with appropriate extensions may also be able to read certain LRF files.
