Oninit Phoenix Forms

Because the reconstruction process is best appreciated by seeing the results firsthand, it can be difficult to demonstrate effectively with a simple example or screenshot alone. The easiest way to understand what the tool can do is to upload a form and let it process it for you.

Simply upload an Informix 4GL compiled form binary (.frm) file, and the tool will analyze the binary structure and reconstruct the original .per source definition. The decompiler is designed to recover the form layout, field definitions, attributes, and other information contained within the compiled form, making it easier to inspect, document, maintain, or migrate legacy applications when the original source is no longer available.

Single-file uploads are supported, and once processing is complete, the reconstructed .per source is rendered directly on the page for immediate review. No additional software, configuration, or manual extraction steps are required.

Source Code Recovery Authorization

Please read carefully before continuing.

This feature is intended solely for recovering source code from executable programs that you own or are otherwise legally authorized to analyze.

By clicking “I Accept” or otherwise continuing, you acknowledge and agree that:

  • You own the software being decompiled, or you have obtained all necessary rights and permissions from the copyright owner.
  • You are legally authorized to decompile and reconstruct the source code from the submitted executable.
  • Your use of this feature complies with all applicable laws, software license agreements, contracts, and intellectual property rights.
  • You understand that unauthorized decompilation of software owned by others may violate copyright, contractual obligations, or other applicable laws.
  • You accept full responsibility for your use of this feature and for any recovered source code.

By selecting “I Accept” and continuing, you certify that the above statements are true and agree that you are solely responsible for ensuring you have the legal authority to use this feature.



We’ll email you a one-time link to begin your upload — this verifies a real address before any file is accepted.

The decompiler runs server-side; nothing is stored. For batch or scripted use, see the ondebug CLI.
