VCFheader browser
The fastest way to understand a VCF before reading a single variant.
Drop a VCF, gVCF, VCF.gz, or gVCF.gz file. We don't read your data. Only the header section is detected to build a structured report in your browser.
Choose file
Drag and drop here, or click to select a local VCF file.
Compressed files are read in chunks with fflate. The page deliberately stops after the header and does not finalise gzip validation, which avoids errors from trailing bytes after the compressed member.
