What is a PREL file?
A .PREL file is a Premiere Elements Project File created by Adobe Premiere Elements, a consumer-level video editing application by Adobe Systems. The file saves the structural data of your video project. This data includes the timeline layout, transitions, text effects, and audio levels. A .PREL file does not contain the actual video or audio media. Instead, it stores references to the media files located on your hard drive.
How to open PREL files?
The primary way to open a .PREL file is by using Adobe Premiere Elements. Professional editors can also import these files into Adobe Premiere Pro with some structural conversion. Under the hood, .PREL files often store their project data in XML format. This data is then compressed into a GZIP archive to save space. Advanced users can manually rename the file extension to .gz, extract it using archive utilities like 7-Zip, and inspect the raw project code using a text editor like Notepad++.
Best practices and troubleshooting
The most common problem with .PREL files is missing media. Because the file only points to video clips, moving or deleting those clips will break the project. Always keep your project file and your raw media files in a dedicated folder. If you send a .PREL file to another person, you must also send the video files, or the project will show blank screens.
Summary
viewer.online/prel analyzes .PREL files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If your file has multiple possible meanings, viewer.online/prel identifies the actual format of the user's file. Because .PREL files often use the known GZIP and XML format, viewer.online/prel can safely open and display them online, eliminating compatibility problems.
