This guide walks through signing a contract PDF with Quick PDF, what to check before you sign, how to handle countersigning, and when a signing service with an audit trail is the better choice. It is general information, not legal advice; for important agreements, consider having a lawyer review the terms.

Before you sign: a quick contract checklist
- The parties: your legal name (or your company's) is correct, and so is theirs.
- What is being exchanged: the work, product or service is described clearly, with deliverables and deadlines.
- Payment: amount, schedule, how invoices are paid, and late payment terms.
- Length and ending: start date, end date, renewal terms, and how either side can terminate.
- Risk clauses: confidentiality, non-compete, liability, indemnity and who owns the work.
- Blanks: no empty spaces the other side could fill in later.
If anything needs changing, ask the other party for a revised version rather than editing their wording yourself. A signed contract should reflect text both sides agreed to.
Choosing the right signature for a contract
Quick PDF's Sign tool lets you draw your signature, type it in one of six script fonts, or upload a photo of your pen signature, in black, blue or dark red ink. For contracts:
- Use the same signature you use on paper where you can: draw it or upload it.
- Type your printed name and title (for example "Jane Doe, Owner") under the signature with Add text if you are signing for a business.
- Create a separate initials signature if pages or changes need initialing.
- Turn on Save for next time so every contract you sign looks consistent.

Countersigning and getting a fully signed copy
A contract usually needs signatures from both sides. With a PDF contract, there are two common orders:
- You sign first: sign, download and send it. The other party adds their signature and sends you the fully signed copy.
- They sign first: they send a contract already signed by them. You add your signature and return it; you now both have the final version.
Always ask for and keep the fully signed copy. Quick PDF does not route contracts between parties, send reminders or keep an audit trail of who signed when; you exchange the file yourselves by email or message.
When to use an e-signature service instead
Signing a PDF yourself is ideal when someone sends you a contract to sign. A dedicated e-signature service can be the better fit when:
- You are the one sending contracts out and need several people to sign in a set order.
- You want an audit trail: a record of email addresses, timestamps and IP addresses for each signature.
- The other party requires a certificate-based digital signature that shows the file was not changed after signing.
Quick PDF adds an electronic signature image on the page. It is not a certificate-based digital signature and does not create an audit trail. Learn the difference in electronic vs digital signature.
Is an electronically signed contract binding?
General information, not legal advice: in the US, the ESIGN Act and the UETA say a contract cannot be denied legal effect just because it was signed electronically. What usually matters is that each party intended to sign and agreed to the terms, and that the signed contract can be kept and reproduced.
Exceptions exist. Wills, certain family law and court documents, and documents that need notarization can follow different rules, and some industries have their own requirements. If you are unsure whether a contract can be signed electronically, check with whoever asked you to sign or with a lawyer.
Keep contracts secure and organized
- Lock it: on fillable contracts, Flatten form on download turns your entries into part of the page. See how to flatten a PDF.
- Protect it: contracts with sensitive terms can be password-protected with Protect before you send them; share the password separately. See send a PDF securely.
- Name it clearly: for example, client name, contract type, date and "signed".
- Store it: keep signed contracts in a folder you back up.
Questions people ask
Can I sign a contract on my phone?
Yes. Save the contract PDF to your phone, open it in Quick PDF in your browser, tap Sign to add your signature and initials, add the date with Add text, then download or share the signed contract.
Is signing a contract electronically legally binding?
In the US, electronic signatures are generally valid for most contracts under the ESIGN Act and UETA, with exceptions such as wills and some court and notarized documents. This is general information, not legal advice.
How do I sign a contract if the other party also needs to sign?
One party signs and sends the PDF to the other, who adds their signature and returns the fully signed copy. Both sides should keep the final version.
Can I edit a contract before signing it?
Technically you can change text in a PDF, but you should not change the other party's wording without their agreement. Ask them to send a revised contract instead.
Does Quick PDF give an audit trail for signed contracts?
No. Quick PDF places an electronic signature image on the page and does not record who signed or when. If you need an audit trail, use an e-signature service that offers one.
Should I type or draw my signature on a contract?
Both can be valid. Many people draw or upload their real signature on contracts so it matches their paper signature, and use typed signatures for routine forms.
