Send a PDF to someone to sign, free: the email round trip that works

By the getPDF team · Published 11 October 2026

The short answer

getPDF has no send-for-signature service, because that needs a server holding your document and here nothing is uploaded. The round trip by email works instead: fill your part, sign it, save, and email the PDF with 1 line of instructions. The other person opens it in their browser, signs with the same free tool (no account on their side either), saves and replies with the file. The last signer flattens if there are form fields, and both of you keep the final copy.

Prepare and sign your part

Sign PDFDraw, type or upload; flatten on save. Free, runs on your device.

The same tool works for both sides. The person who sends the document uses it to fill and sign first; the person who receives it uses it to sign second.

Why there is no “request signature” button

A signing service like Docusign works because your document sits on its server: the service emails the other person a link, shows them the document, records who opened it and when, reminds them, and keeps the signed result. That is a real service, and for some people it is worth paying for (more on that below).

getPDF does every job on your device and sends no file anywhere, which is the whole point of it. That rules out a server holding your lease. So instead of pretending, this page shows the route that needs no server: the PDF travels by your own email, and each person signs on their own device.

The round trip, step by step

A sequence between a landlord and a tenant. The landlord fills and signs the lease and emails it unflattened. The tenant signs, flattens if there are fields, and emails it back. The landlord checks it against the copy sent and confirms receipt. Both keep the final file.Landlord, GrazTenant, Vienna1. fill, sign, Save PDF2. email: lease, signed by landlord, not flattened3. sign, then flatten4. reply: the final lease, signed by both5. check against sent copy6. 1 line confirming receiptBoth keep the final file and the email thread.
The email round trip for 2 signers: what travels in each step, and who flattens.

The sender’s side

  1. Fill your half. Open the PDF in the tool above. Real form fields are tinted; click and type, and Tab moves to the next one. If the lease has no fields, add your text on the lines with the Text tool (press T).
  2. Sign your line. Press New signature, draw, type or upload your signature, press Use this signature and click your line. Add the date with Date.
  3. Save without flattening. Press Save. If the other person still has fields to fill, they must stay fillable, so do not use Save flattened PDF yet. Your signature is already part of the page.
  4. Keep the exact file you send in your own folder. It is your reference when the signed copy comes back.
  5. Email it with 1 short, clear instruction (below).

The signer’s side

  1. Save the attachment and open it in the browser at getpdfs.app/sign-pdf. No account, nothing uploaded.
  2. Fill any fields that are theirs, then New signature, Use this signature, click their line, and Date.
  3. As the last signer, choose Save flattened PDF from the arrow next to Save if the document has form fields, so the answers are fixed in the page. Without fields, Save is enough.
  4. Reply in the same thread with the saved file attached.

The signer does not have to use getPDF: any tool that adds a signature and saves a PDF works. The round trip is the method, not the tool. With 3 or more signers, multiple signatures in order covers who goes when, and sending a signed PDF back the checklist for the reply.

A worked example: a lease from Graz to Vienna

Karol Michał lets a flat in Graz to Jane Cooper, who lives in Vienna. The lease is a 4-page PDF with fields for names, the rent and the start date, a signature line for each of them, and initials boxes in the margins.

Karol fills the fields, signs his line, saves with Save PDF and keeps that file as “lease-cooper-sent.pdf”. Then he writes:

Subject: Lease for the flat in Graz, for your signature

Hi Jane, the lease is attached, filled in and signed by me. Please check it, sign on page 4 under “Tenant” and add the date, initial each page in the margin box, and send the signed PDF back in this thread by Friday. You can sign it in your browser at getpdfs.app/sign-pdf, no account needed. Karol

Jane opens the file, reads it, makes her initials once with the Initials button and places them on each page, signs page 4, adds the date, saves with Save flattened PDF, and replies:

Hi Karol, the signed lease is attached (lease-cooper-signed.pdf). Signed on page 4 and initialled on every page. Jane

Karol opens the returned file, checks that the rent, the dates and the names match his sent copy, and answers with 1 line confirming he has it. Both keep the final PDF and the thread. The thread is the record of who sent what, when: for an everyday lease, that is normally the proof that matters.

What a signing service adds that email cannot

Email round trip A signing service
Cost Free A subscription; Docusign Personal was 11 US dollars a month, billed annually, for 5 envelopes a month
Where the document is Your device, the signer’s device, your mailboxes The service’s servers
Signing order You agree it in the email Enforced by the service
Reminders You send them Automatic
Record of who opened and signed The email thread A hosted audit trail
Account for the signer None None (Docusign’s own FAQ)

Docusign figures from its pricing page, checked on 11 October 2026.

A service is worth its fee and the upload when you send many documents a month, when 3 or more people must sign in a fixed order, when someone might later dispute who signed, or when the recipient’s rules require a certificate or qualified signature. For a lease, a quote or a consent form between 2 people, the email round trip does the job.

The honest part

Nothing in this round trip locks the text. A drawn signature does not stop anyone from changing the document before or after signing, in either direction. That is why you keep the exact file you sent and compare the one that comes back. A certificate signature makes any later change visible; qualified and certificate signatures explains when that is worth it.

There are no reminders and no tracking. If the other person forgets, you remind them. If the file gets lost in their inbox, you send it again.

It proves agreement, not identity. The email thread shows that the file came back from Jane’s address; it does not prove Jane drew the signature. For everyday contracts that is accepted practice; for anything high-stakes, the plain-words guide to signature law explains what more exists. This is not legal advice.

Email itself is not private. Mail can travel unencrypted between some servers. For a lease with ID numbers or bank details, password-protect the PDF before emailing and share the password another way, such as a text message. The pillar guide to signing and filling covers the rest of the job.

Questions

Can getPDF send a document to someone for signature?

No. A signature-request service needs a server that holds your document, tracks it and sends reminders. getPDF uploads nothing, so it has no such server. You send the PDF by email yourself, and the other person signs it with the same free tool.

Does the other person need an account or an app?

No. They open the PDF in their browser at getpdfs.app/sign-pdf, sign, save and reply with the file. They can also sign with any other PDF tool they already use; the round trip works the same.

Who flattens the PDF?

The last person to sign, and only if the document has form fields. Flattening fixes filled fields into the page; if the first signer flattens, the next one can no longer fill their fields. The signatures themselves are part of the page in either case.

How do I know the tenant did not change the lease before signing?

Keep the exact file you sent. When the signed one comes back, compare the pages and the key terms (rent, dates, names) with your copy. A drawn signature does not lock the text; a certificate signature or a signing service's audit trail would.

When is a paid signing service worth it?

When you send many documents a month, need a fixed signing order with reminders, or want a hosted audit trail of who opened and signed what and when. Docusign's Personal plan was 11 US dollars a month, billed annually, for 5 envelopes a month when we checked on 11 October 2026.
