How to sign a PDF document electronically

Prepare

Start with the right version.

Upload the PDF, then place signature, initials, date and text fields where they belong, and give each field to the person who fills it in.

Invite

Invite each signer by email.

Add the signers, then send. Each one gets an email with a link to the signing page. If an invitation can’t be delivered, KuduDoc tells you and gives you a link to share yourself.

Sign

They sign on their own phone.

Each person opens the link with a free KuduDoc account, reads the document and signs. A signer can forward it to a witness when the document calls for one, or decline and give a reason — the reason stays in the record.

Copies made before everyone has signed carry an interim notice.

Signing order

The employer signs first, then the employee. The next person is invited only when the one before them has signed. A fixed order is on Professional; on other plans everyone signs at the same time.

When the last signature lands,
the file is sealed.

KuduDoc records a fingerprint of the exact bytes, adds a certification signature and anchors the time. Years later, anyone can check a copy against that record — free, without an account.

Questions people ask
about electronic signature software

An ordinary electronic signature.
KuduDoc signatures are ordinary electronic signatures. The finished PDF does carry KuduDoc’s certification signature, with a certificate Adobe trusts. It seals the file; it is not a signer’s signature.
Yes, on Professional: set the order before you send, and each person is invited when it’s their turn. On other plans everyone can sign at the same time.
Open the invitation email on your phone and tap the link, then sign in or create a free KuduDoc account. The document opens in your browser, so there’s no app to install. Read it, sign where you’re asked, and you’re done. To send a PDF of your own, upload it, place the fields and invite the signers.
Whether a copy is unchanged since sealing — byte for byte the file that was sealed. It doesn’t tell you whether what the document says is true. Anyone can check a sealed file for free.
Yes. With a free Personal account you can sign a PDF yourself, free, and the PDF stays on your device. Signing from an invitation needs only a free account too. To send a PDF to others, Personal includes 5 sends a month and up to 3 signers per document, with no card and no expiry date.
Personal is free, with no card and no expiry date. Family is $6 a month ($57 a year) and Professional is $12 ($120), per occupied seat, with a 14-day trial. Documents you have already sent are not affected by a plan change. Compare plans.
