Frequently asked questions

Is the business letter generator free and private?
Yes. It runs entirely in your browser — your sender details, recipient details and letterhead logo never leave your device. Nothing is uploaded or stored on a server.
What kinds of letters can I create?
Pick a letter type to start from a ready-made template: a cover letter for a job application, an authorization letter, a demand or formal notice letter, a resignation letter, or a general business letter. You can edit every word.
Can I add my company letterhead?
Yes. Upload a PNG or JPG logo and it appears as a letterhead mark on the letter. Your sender block, salutation, body and signature are all fully editable.
What can I export?
Download a clean, print-ready A4 PDF, or use Print to send it to a printer or save as PDF from the print dialog.
