When the document looks right, you download it or send it straight into PostalForm's mailing flow as a real letter. ## How it works 1. **Open your document** - drop a PDF (or DOCX, image, and other common formats) onto the page at postalform.com/edit-pdf, or try the built-in sample document first. 2. **Make your edits** - add text, fix existing lines, sign, stamp, and arrange pages. Every change previews exactly as it will print. 3. **Download or mail it** - save the edited PDF to your device for free, or click Mail this PDF to have PostalForm print it and send it as First-Class or Certified Mail. ## What the PDF editor can do - **Add text anywhere** - click a spot on the page and type. Choose the size, the color, and a standard print font. - **Fix text that is already in the PDF** - the Edit text tool highlights each printed line so you can replace or delete it in place. It is built for the small fixes that usually force people to recreate a whole document: a misspelled name, an old address, a wrong date, a rent amount. - **Sign without printing** - draw your signature on a signing pad with a mouse, finger, or stylus, then place it on the signature line and resize it to fit. - **Stamp images** - place PNG or JPEG images such as a company logo, a checkmark, or scanned initials, then move and resize them freely. - **Manage pages** - reorder pages from a thumbnail rail, rotate a sideways scan, delete pages you do not need, and insert blank pages. - **Open more than PDFs** - Word documents, Markdown, HTML, text, RTF, and images are converted to PDF automatically when you open them, so you can sign a DOCX contract without owning Word.

The Edit text tool scans the page and outlines each line of printed text. Click a line and you can delete it or type a replacement, which is placed at the same position and size as the original. Two honest limits are worth knowing before you start. Replacing a line does not re-wrap the surrounding paragraph, so this works best for short fields — names, addresses, dates, dollar amounts, reference numbers — rather than rewriting body text. And a scanned PDF is a photograph of a page, not text, so scanned documents can be signed, stamped, and rearranged but not text-edited. ## Sign a PDF without printing it Open the document, choose Sign, and draw your signature on the pad. Place it on the signature line, resize it until it looks natural, and add a typed date next to it if the form calls for one. The result prints exactly like a document that was signed by hand, without the print-sign-scan routine. Many everyday documents — leases, consent forms, letters of authorization, cancellation requests — are accepted with a drawn signature. Requirements vary by document type and jurisdiction, so check what your recipient expects if the stakes are high. ## Edit first, then send it as real mail The editor exists because so much paperwork has to be fixed right before it is mailed. Landlords correct a tenant name on a [late rent notice](/letters/late-rent-notice-letter-template) and send it Certified. Tenants sign a lease renewal and mail it back. Contractors put a signature and date on a [demand letter](/final-demand-letter) before sending it with proof of delivery. When your document is ready, Mail this PDF moves it into the PostalForm mailing flow: enter the addresses, pick First-Class or [Certified Mail](/certified-mail-online), see the exact price before paying, and PostalForm prints and mails it — usually the same business day. Editing and downloading are free; you only pay if you choose to mail something. ## FAQs - **Is the PDF editor really free?** Yes. Opening, editing, signing, and downloading your PDF are free, with no account, no watermark, and no page limit beyond what your browser's memory can handle. Mailing a document through PostalForm is the only paid step, and you see the full price before paying. - **Does my PDF get uploaded to a server?** No. The document is opened and edited in your browser. It leaves your device only if you click Mail this PDF, which sends it to PostalForm for printing and mailing. - **Can I edit text that is already in the PDF?** Yes, on PDFs with real text. The Edit text tool replaces or deletes printed lines in place, keeping the original position and size. Scanned pages cannot be text-edited because they contain a picture of text rather than text itself. - **Is a drawn signature legally binding?** A drawn signature is treated like signing a printout for many everyday documents, and mailing the signed original on paper is often exactly what the recipient wants. For documents with formal e-signature requirements, confirm what your recipient accepts. - **Can I combine several files into one PDF first?** Yes. Use the free PDF merge tool to combine PDFs, Word documents, images, and more into one file — then click Edit PDF on the merged result to sign it or fix it before downloading or mailing. - **What file types can I open?** PDF, DOCX, Markdown, HTML, plain text, RTF, and PNG or JPEG images. Non-PDF files are converted to PDF automatically when opened. ## Related - [Merge PDFs online free](/merge-pdfs-online-free) - [Split a PDF into separate files](/split-pdf-online) - [Edit a PDF without Adobe](/edit-pdf-without-adobe) - [Mail a PDF online](/mail-pdf-online) - [Certified Mail online](/certified-mail-online) - [Landlord notices: templates and state rules](/landlord-notices) ## Ready to send it?
