What is an FR3 file?
An .FR3 file is a FastReport Form File created by Fast Reports. Software developers use these files to store the visual layout, formatting, and data connections for business reports. They contain the blueprint for how a final document will look when printed or exported.
How to open FR3 files?
Normally, you open these files with applications built using FastReport components or with the standalone FastReport Studio. Because an .FR3 file is a template, it usually connects to a database to generate the final document. If you do not have the specific software that created the report, opening the file natively can be difficult.
Inspecting FR3 files online
If you are struggling to open a report template, viewer.online/fr3 analyzes .FR3 files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. This helps you figure out the exact nature of the file without installing specialized reporting software.
Converting to other formats
To share reports with people who do not use Fast Reports, you should export the final document to a standard format. Visit convert.guru to convert your .FR3 files to easily shareable formats like PDF, HTML, or CSV.
Summary
Because .FR3 files use the known XML format, viewer.online/fr3 can safely open and display them online, eliminating compatibility problems.
