Extract text from DEC files
To convert your DEC file to another format, you need Receita Federal IRPF or other Data software.
To convert other file formats to the "Tax Return Form" file type, you need software like Receita Federal IRPF or a similar tool.
The .DEC file extension is a versatile container primarily associated with Tax Declaration data submitted to government agencies in Brazil (Receita Federal), Spain (Agencia Tributaria), and Mexico (SAT). These files often serve as data packages containing sensitive fiscal information, proprietary formatting, or compressed archives (using algorithms like zlib or bzip2) that prevent them from being opened by standard text editors. Users frequently experience issues because these files are strictly tied to the specific year and version of the tax software that created them (e.g., IRPF), rendering them inaccessible once the software is outdated. A secondary but significant use case is for Nintendo Wii decrypted game images, used by emulators like Dolphin, which create large disk dumps incompatible with standard ISO tools.
For tax and administrative documents, the most practical conversion goal is usually PDF for archiving or printing, though this often requires the original generating software to export the view. For users dealing with data archives disguised as .DEC files, converting or renaming to ZIP or TXT can often reveal the internal structure. Gamers managing decrypted Wii dumps should convert these files to ISO or WBFS to ensure compatibility with emulators and reduce file size for storage. Our platform helps identify the specific variant of your file to determine the correct processing path.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DEC converter.
