Are you looking for a way to compile Delphi or Pascal code online? Several tools let you do just that — some are paid, while others are completely free and based on Free Pascal. If you’re stuck, don’t worry — we’re here to help!
A Delphi compiler is a software tool used to translate programs written in the Delphi programming language into an executable format. It translates Delphi source code into machine code that can be executed on a computer. The primary objective of a Delphi compiler is to compile and optimize the source code for execution.
The compilation process involves translating readable Delphi source code into a format understandable by the computer processor. This includes identifying syntactical errors and optimizing instructions to ensure the program runs efficiently.
Although some free online compilers may not be able to convert older versions of Delphi code to newer ones – for example, Delphi 4/5/6/7 to Delphi 12 – they can still compile and debug the code. Compiling Delphi code using a Delphi compiler enables developers to build powerful and efficient applications for various platforms.
They all use the free Delphi compiler, Free Pascal. Free Pascal is a Pascal-compiler that supports the Delphi-syntax. Free Pascal is on GitLab, where you can find and download all files.
Are you still using an old Delphi version and would you like to upgrade to a new version of Delphi? Then it is better to use the GDK Duster. The GDK Duster tools use the Delphi compiler to automatically compile programs, find errors, and modify code to fix these errors. Since all changes are done through actions, you can just grab the latest codebase and start the conversion every time. When developing the GDK Duster tool, we always kept automation in mind.
Are you interested in a personal demo of GDK Duster, or are you looking for help converting a Delphi project? Please contact us at info@gdksoftware.com.
Not exactly. Most online tools use Free Pascal, which is similar to Delphi but not identical. Running full Delphi applications (especially those with visual components like VCL or FMX) typically requires a local IDE like Embarcadero RAD Studio.
Delphi is a commercial product by Embarcadero. Free Pascal (FPC) is open-source and supports much of the same syntax. However, FPC lacks some Delphi-specific libraries (like VCL or FMX), so not all Delphi projects will compile without changes.
Partially. A tools like GDK Duster can automate parts of the conversion, but manual intervention is often needed for UI changes, third-party libraries, and deprecated functions. The developers at GDK Software are happy to personally assist you with upgrading your Delphi project.
