PostalForm prints the PDF, envelopes it, and mails it for you. ## How it works 1. **Upload your PDF — Drag and drop from your computer or select from your phone** - 2. **Preview the print — We show you what will be printed** - 3. **Enter addresses — Sender and recipient, with validation** - 4. **Choose options — Color or black & white, single or double-sided, delivery speed** - 5. **Checkout — We print and mail it** - ## Pricing Postage is included. Large documents (many pages) may add a flat processing fee. Example: A 5-page black & white document costs $3.00 + (5 × $0.20) = $4.00. ## Key takeaways - Upload a single PDF (up to 100 MB and 199 pages) and we print it as-is. - If your PDF is ready, upload it on this page and continue with the file already attached to the order. - Choose color or black & white, plus single- or double-sided printing. - Add Certified Mail for proof of delivery, or choose Express with signature required at delivery when you need faster delivery and the recipient must sign for it. ## Fastest path when the PDF is ready This page is for the direct "upload PDF, print, and mail" job. If the document already exists as a PDF, start here instead of rebuilding the letter or filling out a form again. Upload the file, confirm the addresses, choose print and delivery options, and review the price before checkout. If you are still assembling the document, use [Print and mail a PDF](/print-and-mail-pdf) for print-option guidance or [Mail a form online](/mail-a-form-online) when the document is a form packet. ## Mail PDF online: when this is the right page Use this page when the file is already a PDF and the next job is physical mailing. That includes signed letters, notices, forms, invoices, appeal packets, and other documents that need to reach a U.S. mailing address. If you are mailing a written letter, the related [send a letter online](/send-letter-online) page explains letter-specific timing, signatures, and proof options. If you are comparing printing services first, [print and mail a PDF](/print-and-mail-pdf) covers color, duplex, page-order, and packet setup in more detail. ## What kinds of PDFs people mail **Documents that need signatures** Contracts, forms, agreements. Sign them digitally or print-sign-scan, then mail the final PDF. **Legal and compliance documents** Notices, responses, filings. When email isn't acceptable and physical mail is required. **Business correspondence** Letters, invoices, statements. Sometimes paper is what the recipient expects. **Government forms** Many agencies still require paper submissions. Fill out the form, export to PDF, mail it. **Personal letters** Yes, people still send letters. Especially when it matters. ## PDF requirements - **Format:** PDF only (no Word docs, images, or other formats) - **Size:** Up to 100 MB - **Pages:** Up to 199 pages - **Page size:** US Letter (8.5" × 11") recommended If your PDF has unusual page sizes, margins may be affected. Preview before checkout. ## Print options **Black & white or color** Color costs more ($0.40/page vs $0.20/page). Use it when your document has charts, photos, or branding that matters. Most text documents look fine in black & white. **Single-sided or double-sided** Double-sided (duplex) uses both sides of the paper. Good for multi-page documents, saves postage weight. Some forms specifically require single-sided printing. ## Delivery options **First Class Mail (3–7 business days)** Standard delivery. Appropriate for most mailings. **Priority Mail Express (1–3 business days)** Faster, for time-sensitive documents. You can also require a signature at delivery if needed. **Certified Mail with Electronic Return Receipt** Adds tracking and requires a signature. Available with First Class only. [Learn about Certified Mail](/certified-mail-online) ## Creating a good PDF **From Word, Google Docs, etc.** File → Save As → PDF or File → Download → PDF. This creates a clean, printable document. **From a scanned document** Use your phone's scan feature or a scanner app. Make sure: - All text is readable - Pages are straight (not skewed) - Contrast is good (not too light) - All pages are included in one PDF **Combining multiple files** If you have several documents to mail together, combine them into one PDF first. On Mac, use Preview. On Windows, use the Print to PDF function. Online tools like SmallPDF work too. ## What we can't mail - **Physical items** — We print PDFs. We can't include checks, photos, keys, or anything that isn't on paper. - **International addresses** — Currently U.S. addresses only. - **Same-day delivery** — We're not a courier. Fastest option is USPS Express. ## Common mistakes to avoid **Uploading multiple files** Upload one combined PDF. If you upload separate files, they'll be separate mailings. **Low-quality scans** If we can barely read it, the recipient won't be able to either. Rescan if the preview looks bad. **Wrong address** Use the exact address from any instructions you received. Misspellings and wrong ZIP codes cause returns. **Missing pages** Check your PDF before uploading. Make sure all pages are there and in the right order. ## Related - [Print and mail a PDF](/print-and-mail-pdf) - [Send a letter online](/send-letter-online) - [Can you send a letter online for free?](/send-a-letter-online-free) - [Mail documents online](/mail-documents-online) - [Mail a form online](/mail-a-form-online) - [How to mail a PDF online](/how-to-mail-pdf-online) - [Print and mail cost calculator](/pricing-calculator) - [Send a letter without a printer](/send-letter-without-a-printer) - [Delivery times](/delivery-times) - [Pricing](/pricing) ## Ready to send it?
