Frequently Asked Questions
Here are some common questions and answers about chm file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Can I convert encrypted archives without the password?
A: Unfortunately, if an archive is encrypted, you’ll need the password to convert it. We cannot bypass encryption for security reasons.
Q: Are there limits on how big my archive file can be for conversion?
A: Our conversion platform can handle pretty large files, but there may be a limit depending on the file type and server load. For most users, it's more than enough for typical archive sizes.
Q: What should I do if the archive file I uploaded isn't processing?
A: If your archive isn’t processing, try uploading it again or check if the file is in a supported format. If the problem continues, our support team is available to assist you.
Q: Can I convert files inside a password-protected archive?
A: We currently can’t handle password-protected archives directly. You’ll need to extract the files first, then upload the unprotected contents for conversion.
Q: What happens if I upload an empty archive?
A: If you upload an empty archive, the conversion process will be quick but will result in an empty converted file. Make sure your archive contains data before uploading.
Q: What should I do if I encounter an error while converting an archive?
A: If you run into any errors, try re-uploading the file. If the issue persists, you can contact our support team, and we’ll be happy to help resolve the problem.
Q: Can I convert a file from a password-protected ZIP file?
A: You’ll need to extract the files first using the correct password. Once extracted, you can upload the contents and convert them to another format.
Q: How do I manage large archives for conversion?
A: For larger archives, you might want to break them into smaller files. This can make the conversion process smoother and faster. If needed, our platform can handle batches of smaller files for you.
Q: Can I convert archive files for free?
A: Yes, all our archive conversions are free. No need to pay a dime—just upload, select the format, and we’ll take care of the rest!
Q: Can I convert an archive file from a network drive?
A: Yes, as long as your network drive is accessible from your device, you can upload and convert files directly from it. Just make sure it’s online and connected!
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.

On Windows, Calibre is a popular tool for reading and managing EPUB files, while macOS users can use Apple Books or other third-party apps like Calibre or BookReader.
