How long should a cover letter be?

Three short paragraphs on one page is usually enough: why this role, what you have done that matters for it, and a brief close.

Can I reuse the letter for different jobs?

Yes — save it as a template and change the company, role and highlights each time, or ask the AI to rewrite it for a new job description.

Does it match the resume template?

Yes. The header uses the same name, title and contact block, so the two documents look like a set.

Cover letter PDF maker

A polished cover letter with a matching header, addressed to the hiring manager — pairs with the resume.

A good cover letter is short, specific and tailored to the role. Tell PDFgen the job, the company and two or three things you want to highlight, and it drafts a three-paragraph letter on a clean letterhead that matches the resume template.

Adjust the wording with a click, then download a PDF ready to attach to your application.
