3 ways to sign · 1 legally binding result

Sign the way you sign best.

Draw with your finger, type your name, or upload a photo of your handwritten signature. All three are valid under eIDAS, ESIGN Act and UETA.

01

Draw

Use your mouse, your trackpad, or your finger on mobile. The most personal option — your real signature, captured digitally.

02

Type

Type your name and we render it in a handwritten style. Fastest option when you just need to get it done now.

Upload

Scan or photograph your handwritten signature once. Upload as PNG or JPG and we'll reuse it on every future document.

When the ink can't wait

Four signatures, four deadlines that didn't wait.

The moments when printing, scanning and emailing back is not an option.

schedule 07:42 · Tuesday

"NDA before standup."

A founder in Lisbon gets a Series-A NDA at 7 AM. Coffee in one hand, baby in the other. Signed from the phone in 14 seconds — investor opens at 9:01.

schedule 23:48 · Saturday

"Lease addendum, signed."

A landlord in Madrid closes a midnight lease addendum. Edits two clauses, signs with the trackpad, sends the PDF before the tenant boards a flight to Buenos Aires.

"Offer letter, return ASAP."

A new hire in Berlin gets her offer at the end of the week. Reads it on the train home, signs with her finger before her stop, sends it before HR closes for the weekend.

"Vendor contract, before invoice."

"Signed 11 contracts from a boarding gate."

Quarter-close week. I had to send 11 vendor contracts before Friday. Did them all from JFK boarding gate, on the phone. Each one took under 30 seconds. Saved me a weekend.

"My signature finally works on tablet."

I switched from DocuSign for the consumer pricing — but ended up loving it for the iPad stylus support. My signature actually looks like me again. That detail matters when sending to clients.

"Finally a signer my dad can use."

I sent my 70-year-old father a real-estate document to sign. He drew his signature on the iPad without calling me once. That's the highest praise I can give any software.

Yes. CosmicPDF signatures comply with eIDAS in the EU, the UK Electronic Communications Act, the US ESIGN Act & UETA, and equivalent laws worldwide — making them legally binding for contracts, NDAs, offer letters and most legal documents. Every signature includes a tamper-evident audit trail with timestamp, IP and signer details.
Same legal weight, different methods. Draw uses your mouse, trackpad or finger — most personal. Type renders your name in a handwritten font — fastest. Upload uses a saved image of your handwritten signature — best if you sign often and want consistency.
Yes — fix a typo, fill a form field, add a date or initials, redact something sensitive. All in the same tool, no need to export, edit elsewhere and re-import.
Yes. After you sign, you can email the PDF directly or generate a secure share link. For multi-party signing flows (contract requires both parties), use our Send for Signature feature.
Every file is encrypted with 256-bit SSL during upload and at rest, then auto-deleted 1 hour after you finish. We never look at your files, never train AI on them, and never share them. SOC 2 Type II certified, HIPAA-ready and fully GDPR compliant.
No. Electronic signature law doesn't require a visual match to a wet-ink one — what matters is your intent to sign and the audit trail proving it was you. The signature can be your name in cursive, your initials, or even just an "X".
Fully. Sign with your finger on iPhone or Android, with a stylus on iPad or Surface, or with your trackpad on a laptop. No app required — everything runs in your browser.
