Convert between common bioinformatics formats — FASTA, BED, GFF3, GTF2, and VCF — without needing command-line tools. Use this tool when a collaborator sends annotations in an incompatible format, when migrating data between analysis pipelines, or when preparing files for submission to public databases such as NCBI or Ensembl. The validated output preserves essential annotations and can be downloaded directly for use in genome browsers like IGV or as input to downstream analysis tools.

Features

• FASTA Input: Paste sequences in FASTA format with optional annotations
• BED Output: 3-column minimal or 6-column BED format
• GFF3 Output: Full 9-column General Feature Format
• GTF2 Output: Gene Transfer Format with gene_id/transcript_id attributes
• VCF Output: Variant Call Format with standard columns
• File Download: Save converted output as .bed, .gff, .gtf, or .vcf
