# Can you send a letter online through USPS?

You can use USPS online tools to buy stamps, calculate postage, create package labels, and use Click-N-Ship or Label Broker for eligible shipping labels. USPS does not offer a simple consumer workflow where you upload an ordinary letter PDF, have USPS print the pages, put them in an envelope, and mail it for you.

## Quick answer
Use USPS directly when you already have the physical letter or need USPS-specific counter help. Use PostalForm when the starting point is a PDF, DOCX, typed letter, signed form, or document packet that still needs to be printed and mailed.

| Search intent | Direct answer | Best next step |
| --- | --- | --- |
| Send a letter online through USPS | USPS does not provide a general upload-letter-and-mail workflow for ordinary letters. | Use USPS if the envelope is ready; use PostalForm if the letter is digital. |
| Print postage online for a letter | USPS sells stamps and has postage tools, but ordinary letters still require a prepared envelope. | Buy stamps or visit USPS if you are mailing yourself. |
| Click-N-Ship a letter | Click-N-Ship is mainly for package labels and eligible shipping workflows. | Do not treat it as a document-printing service. |
| USPS print my letter PDF | Label Broker prints eligible shipping labels, not document pages. | Use [Can USPS print my PDF?](/can-usps-print-my-pdf). |
| Mail a letter without printer or stamps | USPS still expects a prepared mailpiece. | Use [Send a letter online](/send-letter-online). |

## What USPS can do online
USPS online tools are useful, but they solve different jobs:

| USPS tool | What it is for | What it does not do |
| --- | --- | --- |
| Postal Store | Buying stamps and mailing supplies | Printing and mailing your letter content today |
| Price calculator | Estimating postage from size, weight, shape, and destination | Preparing the envelope or printing the document |
| Click-N-Ship | Creating shipping labels for supported packages | Printing ordinary letter pages |
| Label Broker | Printing eligible shipping labels for people without a printer | Printing the PDF document that goes inside an envelope |
| Location finder | Finding Post Offices, kiosks, and dropoff points | Replacing the need to prepare the letter |

## What PostalForm does instead
PostalForm is for the earlier step: turning a digital document into physical mail.

1. Upload a PDF or write the letter online.
2. Review the printable PDF.
3. Enter sender and recipient addresses.
4. Choose available print, delivery, and proof options.
5. See the price before checkout.
6. PostalForm prints, envelopes, adds postage, and hands off the mailpiece.

That is why PostalForm costs more than a stamp. The price includes the work of printing and preparing the letter, not just postage.

## When USPS is still the right choice
Use USPS directly when:

- You already printed the letter.
- You have an addressed envelope and correct postage.
- You need a same-day hand-cancelled postmark at a retail counter.
- You need clerk help weighing a physical mailpiece.
- You are mailing physical originals, checks, IDs, photos, keys, or anything PostalForm cannot print.

Use PostalForm when:

- The document is still on your phone or computer.
- You do not have a printer, envelope, or stamps.
- You want a PDF preview before mailing.
- You want available Certified Mail or Express options shown during checkout.
- You need to mail from a browser without a Post Office trip.

- **Can USPS Click-N-Ship send letters?** Click-N-Ship is for shipping labels and package workflows, not printing the pages inside an ordinary letter.
