Free online PDF editor that keeps your document on your device

PostalForm's free PDF editor lets you open a PDF in your browser, type new text onto any page, draw a signature with your mouse or finger, replace a name or date that is already printed in the document, stamp a logo or scanned initials, and reorder, rotate, or delete pages. When the document looks right, you download it or send it straight into PostalForm's mailing flow as a real letter.

How it works

Step 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.

Step 2

Make your edits

add text, fix existing lines, sign, stamp, and arrange pages. Every change previews exactly as it will print.

Step 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.

Fix a name, date, or amount without recreating the document

The most requested PDF edit is also the one most tools refuse to do: changing text that is already part of the document. 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 and send it Certified. Tenants sign a lease renewal and mail it back. Contractors put a signature and date on a 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, 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.
