About File-Extension.com
The trusted resource for opening any file format since 2020. Free, accurate, and always up-to-date.
Our Mission
File-Extension.com was founded with a simple mission: help everyone open any file, on any device, for free.
We've all experienced the frustration of downloading a file only to find that our computer doesn't know how to open it. Whether it's an obscure document format, a video file with missing codecs, or a compressed archive, getting the right information shouldn't require technical expertise or expensive software.
That's why we created File-Extension.com — a comprehensive, free resource that explains how to open, edit, and convert over 500 different file formats. Every guide is written by experienced tech professionals, reviewed for accuracy, and updated regularly to reflect the latest software and methods.
