Our take
US documents & attachments
A focused option when your files are ready and the recipient is in the United States. Multiple source files become one print preview, so you can inspect the document before paying.
What it offers
- PDF, Word, and photos
- No account needed
- First-Class or Certified
Upload PDFs, Word files, or photos and combine them into a US Letter document. Review the print file and full price, then choose USPS First-Class or Certified Mail for a US address. Guest checkout keeps occasional sending simple.
Setup and pricing approach
No account needed. Pay per letter.
