Extract text from DNA files
To convert your DNA file to another format, you need SnapGene or other Data software.
To convert other file formats to the "Bioinformatics Sequence File" file type, you need software like SnapGene or a similar tool.
A .dna file is primarily a proprietary data container created by SnapGene, widely used in molecular biology to document, visualize, and simulate DNA sequences and cloning procedures. Unlike universal text-based formats, these files store rich metadata - including plasmid maps, feature annotations, and history logs - in a binary format that standard text editors cannot read. This proprietary nature is a major limitation: viewing the file usually requires the specific SnapGene Viewer or a paid license, limiting collaboration with researchers using different software suites. Additionally, files can become inaccessible if the specific software version is obsolete.
To overcome these interoperability barriers, users frequently convert .dna files to open standards. For sequence alignment and processing in tools like BLAST, converting to FASTA or TXT is essential. For preserving annotations while maintaining compatibility with other bioinformatics tools (like Benchling or Vector NTI), the GB (GenBank) format is the industry standard. If the goal is simply sharing the visual plasmid map with colleagues or for publication, converting to PDF or PNG ensures the visual layout is preserved without requiring specialized software. Note: A small minority of .dna files may relate to Epic Games MetaHuman identity data or legacy CA Backup archives.
Convert.Guru analyzes your DNA file, detects the exact format, and lets you read the text inside.
Users also converted GDNA, GBK, GZ, VCF, TXT, DNG, MP3, CSV, PDF, SLDPRT, SPV, ZIP and MUSIC files.
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 DNA converter.
