How to extract sliding windows from a protein

Paste a protein sequence, as plain text or FASTA.
Set the window size and the step between the start of one window and the next.
Each window becomes a FASTA record with its position in the title.

Frequently asked questions

How do I make overlapping peptides?

Set the window to the peptide length and the step to how far each peptide moves along, for example 15 and 5 for 15-mers that overlap by 10.

Is my sequence uploaded?

No. Everything runs in your browser, so your sequences never leave your device.
