How to Convert CHM to EPUB
Click inside the file drop area to upload your CHM file or drag & drop it.
Locate your CHM file on your device—typically used for various purposes. Ensure the file is under 50MB to avoid upload issues. If the upload fails, check your internet connection or try compressing the file first.
Select EPUB as the output format and click the 'Convert' button.
Choose EPUB based on your needs—different formats suit different purposes, like JPEG for smaller file sizes. The conversion process typically takes a few seconds, depending on file size and server load.
Download the converted EPUB file instantly after conversion.
Once the conversion is complete, click the download link to save your EPUB file. You can then open it in software like a compatible viewer. If the file doesn’t download, ensure your browser allows pop-ups from RunConvert.
You can also send a link to the converted file via email. (Optional)
Enter an email address to receive a secure link to your converted file, which is useful for sharing with clients or accessing later. Links expire after 24 hours for security, and RunConvert ensures your data is protected during transmission.

Frequently Asked Questions
Q: Can I convert an archive file on mobile?
A: Yes! You can easily convert archive files from your mobile device using our platform. Just upload the file, select the format, and you’re good to go!
Q: Why should I convert my archive files?
A: Converting your archive files can help with compatibility, reduce file sizes, or just make them easier to manage with different software. It’s all about making your files work better for you!
Q: Can I convert files from a .tar format?
A: Yes, you can! We support converting files from .tar to other popular formats like .zip, .rar, or .7z. Just upload your .tar file and choose the format you want it converted to.
Q: Why would I choose 7z over ZIP?
A: 7z is known for its better compression rates and handling of larger files. If you're looking to save space without compromising on quality, 7z is a solid choice.
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 should I do if my archive has a very large file inside?
A: If your archive contains a very large file, we recommend checking the file size before uploading. Large files might take longer to convert, and it's best to ensure they don't exceed our file size limits.
Q: Can I convert an archive with system files inside?
A: While we can convert most archives, be mindful that system files or hidden files inside your archive may not always be handled correctly. It’s best to avoid system-specific files for conversion.
Q: What happens if my archive conversion fails?
A: If your conversion fails, don't stress! We’ll let you know the issue, and you can try uploading it again or reach out to us for help. We’re here to make sure everything works smoothly.
Q: Is archive conversion safe?
A: Yes, we take security seriously. We ensure that all files are processed securely, and we don't store them longer than necessary. Your privacy and the safety of your files are a top priority.
Q: What’s the best archive format for large files?
A: For larger files, 7z is often considered the best due to its high compression rates. If you want to reduce the file size significantly without losing quality, 7z is your go-to format.
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.
