Frequently asked questions

Will the letterhead cover my text?

No. With "Behind content" the letterhead goes under your text and pictures, so everything stays readable.

Can the first page have a different letterhead?

Yes. Use a two page letterhead PDF and choose "Page 1 on first page, page 2 on the rest".

Does it work with scanned letters?

Yes. Behind mode blends the letterhead so that white paper in your scan does not hide it.

Is it really free? Do you add a watermark?

Yes, it is completely free with no sign-up, no watermark and no daily limits. The site is supported by a few non-intrusive ads.
