Before processing large files
On phones and tablets, start with files under 20 MiB and keep this tab in the foreground. Video, OCR and 3D operations can use several times the input size in memory. Desktop browsers generally have more room, but the 128 MiB job limit is not a guarantee that every file will fit. Smaller batches reduce memory pressure.
Supported input formats
- VCF file (genomic variants or vCard contacts; tool-specific) (.vcf)
Output format
Comma-separated values (.csv)
Support applies to this conversion direction. Check the limits below for features that may change or be discarded.

- Add your supported file using the chooser or drop zone.
- Review the settings and conversion limits before processing.
- Select Convert files, then download the result.
What to expect
- UTF-8, uncompressed input only, maximum 64 MiB, 100,000 records and 2 million cells. No assembly or coordinate-system conversion. Missing values remain literal dots; CSV cells are not sanitized for spreadsheet formulas.
- Plain VCF 4.1–4.5 with ##fileformat and #CHROM headers. INFO, FORMAT, ALT and sample genotypes stay literal strings; no variant normalization, allele splitting, reference lookup or genotype interpretation. This is genomic VCF, not a vCard contact file.
Engine: Local genomic table parser. The engine may need a first-use download. Your file stays in this browser session.Check conversion engines and offline requirements.
About this conversion
Is genomic vcf variants to csv free?
Yes. This tool runs on your device without an account or a conversion fee.
Are files uploaded during conversion?
File processing happens locally in your browser. Engines may download their code on first use; your input files are not sent to a conversion server. Read how file privacy works.
What if conversion fails?
Check that the file matches a supported input, review the engine’s limitations and try a smaller representative file. If the engine cannot load, check its engine assets and browser requirements. The app reports failures without switching to a remote converter.
