Question 1

How large can my PDF files be?

Accepted Answer

BuiltSign supports PDF files up to 1GB. Unlike most e-signing tools that cap at 25MB, we've built our upload technology from the ground up to handle large files fast and reliably — so your extensive contracts, legal bundles, and media-rich documents upload seamlessly.

Question 2

Are signatures legally binding?

Accepted Answer

Yes. Electronic signatures created with BuiltSign are legally binding under the EU eIDAS regulation and the US ESIGN Act. Every signed document includes a full audit trail with timestamps, IP addresses, and signer verification — providing the evidence you need if a signature is ever challenged.

Question 3

What happens to my documents after signing?

Accepted Answer

Your documents are encrypted at rest (AES-256) and in transit (TLS 1.3). We store them on enterprise-grade cloud infrastructure with automatic backups. You can download or delete your documents at any time — we never share or sell your data.

Question 4

Can I invite others to sign?

Accepted Answer

Absolutely. Add multiple signers with just their email address. Each signer receives a secure link to view and sign the document — no account required. You'll get notified the moment everyone has signed.

Question 5

How can BuiltSign handle such large files?

Accepted Answer

We've engineered our upload pipeline to break large files into smaller pieces and transfer them securely in parallel. This means your 800MB contract uploads just as smoothly as a 2MB invoice — fast, encrypted, and reliable even on slower connections.

Question 6

Can I cancel or change plans anytime?

Accepted Answer

Yes. All plans are month-to-month (or yearly if you choose the discount). You can upgrade, downgrade, or cancel at any time from your dashboard. If you cancel, you keep access until the end of your billing period.

Question 7

Do I need a credit card to start?

Accepted Answer

No. You can create a free account and start your 7-day trial without entering any payment information. During the trial, you get full access to all features. You only need to add a payment method when the trial ends and you want to continue.
