We would like to hear from you, especially if you have spotted something that needs fixing. The site covers a large number of file formats, and reader corrections are one of the best ways we keep it accurate.
Report a correction
If a download link is dead, a fact looks wrong, or an extension is missing entirely, please tell us. Include the page and the extension in question so we can find it quickly. When we can, we check format behaviour on real systems before publishing, so a clear description of what you are seeing helps us confirm and fix it faster.
How to reach us
Use the form on this page, or email us at [email protected]. This is also the address for questions about the site, the tools, or your data. We read every message and try to reply within a reasonable time.
