Yes, you can get a legally valid electronic signature for free. GSD's sign-pdf tool lets you sign a PDF yourself in your browser at no cost and with no account, and the Free plan lets you send documents to other people for signature too. The catch with any "free" e-signature offer, from any vendor, is that free almost always means capped. Usually the cap is on how many documents you can send per month, how long the finished files are kept, whether you can add your own branding, or how detailed the audit trail is. This page covers what those caps typically look like and what GSD's free tier includes, so you know what you're getting before you rely on it for something that matters.
What "free" usually means across e-signature tools
Signing a document yourself (adding your own signature to something you already have) is free with most tools, including GSD. There's no envelope to track, no other signer to notify, and nothing to store beyond the file you download. Sending a document out for someone else to sign is where free tiers get restrictive, because now the vendor is hosting the document, tracking signer status, and storing the completed file. Across the market, free sending tiers typically restrict one or more of these:
- Volume. A cap on how many documents (or "envelopes") you can send per month before you need to pay.
- Retention. How long the platform keeps your completed, signed document before it's deleted or becomes inaccessible.
- Branding. Whether your company logo and colors appear on the signing page, or the vendor's branding shows instead.
- Audit trail detail. Whether the free tier includes a full tamper-evident record (timestamps, IP addresses, a hash of the file) or a lighter version of it.
- Users and templates. Free tiers are usually single-user and may not include reusable templates for documents you send repeatedly.
None of that makes free tools unreliable. "Free" is a starting tier, and what matters is knowing which of those limits apply before you build a workflow around it.
What GSD's free plan actually includes
GSD's Free plan costs $0, requires no credit card, and supports 1 user. It includes:
- 5 documents a month sent for signature, with AI automatically placing signature, date, and text fields for you to review before sending.
- Unlimited free signing and receiving. Anyone signing a document you send, or any document you sign yourself with the sign-pdf tool, does so in their browser with no account, no app, and no download. This is always free and unlimited, whatever plan you're on.
- A full audit trail on every completed document: signer IP addresses, timestamps, and a SHA-256 hash of the signed file, plus a Certificate of Completion. The free tier's records are as tamper-evident as the paid tiers'.
- 30 days of retention for completed documents. This is the one limit to plan around. After 30 days, a document you signed on the Free plan is no longer stored on GSD's side, so download and keep your own copy of anything you'll need later.
If you occasionally need to send more than 5 documents in a month and don't want a monthly plan, GSD's pay-as-you-go credits cover the overage: $0.05 per page for the first 10 pages of a document, then $0.01 per page after that. The credits never expire. That makes it realistic to stay on Free indefinitely and pay small amounts for the odd busy month, rather than committing to a subscription for a handful of documents. To compare what each paid tier unlocks (more seats, templates, custom branding, longer retention), see the pricing page.
Free tools you can also use without signing up
Two GSD tools work with no account at all, whether or not you ever create one:
- Sign a PDF: upload a PDF, add your own signature, download it. See the full walkthrough in how to add an electronic signature to a PDF.
- Signature generator: draw or type a signature and download it as an image to reuse anywhere.
Before you rely on a free tool for a binding contract
A free electronic signature is as legally valid as a paid one. The ESIGN Act and state UETA laws don't care what you paid. Still, before you use any free tool for something you may need to defend later (a client contract, an employment agreement, a lease), check three things:
- Does it produce a real audit trail? Look for a record that captures the signer's identity confirmation, a timestamp, an IP address, and ideally a hash proving the file wasn't altered after signing. See what makes an audit trail court-admissible.
- How long will the completed file be retained? If the free tier only keeps documents for a short window, download your own copy right after signing instead of assuming you can retrieve it later.
- Is it actually ESIGN/UETA compliant, or just "sign here"? A basic drawing tool that pastes an image of a signature onto a PDF isn't the same as a platform that generates a Certificate of Completion and a verifiable record. For most everyday contracts either can bind the parties if the intent to sign is clear, but only the second gives you real evidence if the signature is ever disputed. See are electronic signatures legally binding.
If you need other people to sign documents regularly, walk through how to send a PDF for signature to see the full sending workflow. Then decide whether Free's 5-document cap and pay-as-you-go overage fit your volume, or whether a paid plan is worth it for the extra seats, templates, and longer retention.
Frequently asked questions
Is a free electronic signature legally binding?
Yes. Whether a signature is legally binding depends on the signer's intent and the record kept, not on whether the tool was free or paid. Under the US ESIGN Act and UETA, an electronic signature carries the same legal weight as a handwritten one for the vast majority of contracts.
What's the catch with free e-signature tools?
Free tiers almost always cap something: how many documents you can send per month, how long completed documents are stored, whether you can add your own branding, or how many users can access the account. The signing experience itself, meaning what a signer sees and does, is usually the same on free as on paid.
Can I sign a PDF for free without creating an account?
Yes. GSD's sign-pdf tool lets you upload a PDF, add your signature, and download the signed file with no account and no cost. That covers signing a document yourself. Sending a document to other people to sign uses GSD's Free plan, which does require a free account.
How long does GSD keep my free signed documents?
30 days on the Free plan. After that, the completed document is no longer retained on GSD's side, so download a copy for your own records right after signing. Paid plans extend retention to 1 year (Pro) or 7 years (Business).
What happens if I need to send more than 5 documents a month on the Free plan?
You don't have to upgrade right away. GSD's pay-as-you-go credits let you send additional documents at $0.05 per page for the first 10 pages and $0.01 per page after that. The credits never expire, so the occasional extra document doesn't require a subscription.
