How it works on mobile

  1. Get your document into PDF β€” Already have a PDF? Great. Need to scan something? Use your phone's scanner.
  2. Upload to PostalForm β€” Select the file from your phone
  3. Enter addresses β€” Autocomplete makes this fast on small screens
  4. Preview and checkout β€” See exactly what will print, pay, done

We print it, put it in an envelope, add postage, and hand it to USPS.

Scanning documents with your phone

If you have a paper document (a signed form, a letter, etc.), scan it to PDF first:

iPhone (built-in scanner):

  1. Open the Notes app
  2. Create a new note
  3. Tap the camera icon β†’ "Scan Documents"
  4. Position the camera over your document
  5. It auto-captures when aligned (or tap manually)
  6. Add more pages if needed
  7. Tap "Save" β†’ then share/export as PDF

iPhone (Files app):

  1. Open Files app
  2. Tap the three dots menu β†’ "Scan Documents"
  3. Scan and save to Files

Android (Google Drive):

  1. Open Google Drive app
  2. Tap the + button β†’ "Scan"
  3. Capture pages
  4. Tap checkmark to save as PDF

Any phone (third-party apps):

  • Adobe Scan (free, works well)
  • Microsoft Lens (free, good for documents)
  • CamScanner (free tier available)

Tips for good phone scans

Lighting β€” Find bright, even light. Natural daylight near a window works well. Avoid shadows across the page.

Angle β€” Hold your phone parallel to the document, directly above it. Tilted angles cause distortion.

Stability β€” Keep your hand steady. Rest elbows on a table if needed.

Background β€” Place the document on a contrasting surface (dark document on light background, or vice versa).

Focus β€” Wait for the camera to focus before capturing. Blurry text is hard to read.

Preview β€” Check the scan before saving. Zoom in to make sure text is readable.

Uploading from your phone

Once you have a PDF, uploading is straightforward:

  1. Go to PostalForm on your phone's browser
  2. Tap "Upload" or "Choose file"
  3. Select the PDF from Files (iOS), Google Drive, or wherever you saved it
  4. Confirm the upload

You can also upload directly from:

  • Email attachments (tap and hold β†’ share β†’ open in browser)
  • Cloud storage (Dropbox, iCloud, Google Drive)
  • Messaging apps where someone sent you a file

Mobile checkout

Our checkout is designed for small screens:

  • Large tap targets for buttons and inputs
  • Address autocomplete (fewer typos)
  • Apple Pay and Google Pay supported
  • Clear total shown before payment

No account required. Just pay and we mail it.
