About FSA files

The .fsa extension acts as a container for three distinct types of data, often causing confusion. Primarily, it is a Fragment Analysis Data file generated by Applied Biosystems genetic analyzers. These are proprietary binary files containing raw DNA sequencing chromatograms (traces), essential for genotyping and microsatellite analysis. The main challenge is that they are not human-readable; they require expensive, specialized software like GeneMapper or Peak Scanner to interpret, making them difficult to share or archive without conversion.

Secondly, .fsa is frequently used as a shorthand for the FASTA format, a standard text-based method for representing nucleotide sequences used in bioinformatics tools like NCBI BLAST. While simple, these lack the rich annotation of GBK files.

Lastly, users of Video DownloadHelper may encounter .fsa files as Fast Stream Archives - temporary video chunks that failed to finalize into a playable movie.

Conversion Recommendations:

For DNA Analysis: Convert proprietary .fsa traces to standard FASTA (text) for sequence alignment, or PDF for visual reports of the chromatogram.
For Bioinformatics: Convert text-based .fsa sequences to TXT for general editing or GBK for annotated archiving.
For Video: If the file is a media archive, it must be converted or finalized to MP4 or MKV to be playable in standard players like VLC Media Player.

Convert.Guru analyzes your FSA file, detects the exact format, and lets you read the text inside.

Users also converted MP4, FASTA, ASF, AXD, TS, VRIMG, PDF, ZIP, FLP, JSXBIN, MKV, KRA and ZST files.

The FSA Converter Story

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 FSA converter.
