Free Dropbox Sign (HelloSign) alternative — no upload, no account.

Dropbox Sign (the product formerly called HelloSign) is a strong hosted e-signature tool if you already live in Dropbox and want templates, reminders, and signed files auto-saved to cloud folders. It is also a product where every PDF you send for signature is uploaded and stored so Dropbox Sign can route it. FreeSign is a structurally different option: a browser ceremony that outputs a PAdES-B-T seal with zero document upload, no account, and no monthly meter.

The structural difference

Dropbox Sign is an e-signature workflow product. Per their published pricing page (checked 12 October 2026), paid plans advertise unlimited signature requests, templates, reminders, audit trails, integrations (Google Drive, Microsoft Word, HubSpot, Salesforce and more), and documents “stored and encrypted at rest using AES 256-bit encryption,” with compliance claims covering SOC 2 Type II, ISO 27001, eIDAS and GDPR. The architectural baseline is that Dropbox Sign holds the document so it can prepare fields, email recipients, and keep a hosted copy.

FreeSign is a cryptographic signing primitive with a thin ceremony shell. The PDF is hashed locally in your browser. A per-user X.509 leaf certificate is issued for that one ceremony from an HSM-backed CA. The CMS PKCS#7 seal is appended to the PDF as an incremental update, and the signed-region hash receives an independent OpenTimestamps proof. FreeSign’s Worker sees the OTP-verified email, the OTP challenge, the SHA-256 hash, the public half of your browser ceremony key, the audit hash chain, and a standard request fingerprint — not the PDF.

Both products aim at legally valid electronic signatures under US ESIGN/UETA-style evidence models. FreeSign’s output is a PAdES-B-T CMS seal you can inspect with Adobe Reader, openssl, and pyHanko; Dropbox Sign advertises a per-document digital seal on its pricing page without publishing that same validator matrix there. The practical difference for most buyers is what the vendor holds — and whether you need their hosted inbox.

Side-by-side

Privacy: who can see the PDF?

Dropbox Sign. Documents you prepare and send are uploaded so recipients can open a signing link, fields can be placed, and a hosted copy (plus audit trail) can be retained. Their pricing page states AES-256 encryption at rest and lists SOC 2 Type II, ISO 27001, eIDAS and GDPR among compliance claims. The trust model is: you accept that Dropbox Sign (and, via integrations, often Dropbox or Drive) holds the file, and you rely on their security and retention controls.

FreeSign. FreeSign cannot read your PDF because we don’t have it. The Worker receives a SHA-256 of the document and a digest of the signature ByteRange. The MCP discovery contract (documentUpload: false) is enforced by a public-contract test. After you download the sealed PDF you can store it wherever you already trust — including your own Dropbox folder — without making Dropbox Sign the signing vault.

If your process requires the e-signature vendor to host the agreement for discovery or a counterparty portal, Dropbox Sign (or DocuSign / Adobe Sign) is the right shape. For confidential one-offs — NDAs, term sheets, board packs — not uploading is often the better default.

Pricing: what “free” means on each side

FreeSign is free today for unlimited ceremonies, with no account and no card. Enterprise options (AATL green check, SSO, SMS/KBA verification) are available on request — see pricing; the free product will not be retroactively gated.

Dropbox Sign’s pricing page (checked 12 October 2026) lists Essentials from $15 USD/mo and Standard from $25 USD/user/mo on the monthly rates shown. Paid plans advertise unlimited signature requests, templates, reminders and team admin features. A 30-day free trial of paid features is offered; the page also links a free path aimed at people who only need to sign a document they received. Yearly billing and seat minimums are shown on that page and can include time-limited promotions — always re-check before buying.

When Dropbox Sign is the right choice

• You want templates, bulk send, SMS authentication, branding, or an admin console out of the box.
• You already work in Dropbox and want signed files to land in a shared folder automatically.
• You need HubSpot / Salesforce / Microsoft Word native send-from-app flows more than privacy-of-bytes.
• The counterparty already expects a Dropbox Sign / HelloSign email link and will not open another tool.
• Your compliance process requires the e-signature vendor to retain the hosted agreement.

Embed in your product vs Dropbox Sign’s cloud

Dropbox Sign’s API and embedded products still centre on their document cloud. FreeSign embed is the opposite shape: your site hosts the PDF, the ceremony runs in an iframe, and the signed bytes return to your callback — FreeSign still only sees hashes. Useful for portals that need a “sign here” step without becoming a Dropbox Sign storage customer. Not a replacement for their template gallery or bulk-send UI. Embed signing guide.

When FreeSign is the right choice

• The document is confidential and you do not want Dropbox Sign (or any e-sign vendor) to hold it.
• You want unlimited free signing without creating a sender account.
• You want signing inside your web app (iframe embed) while keeping PDF bytes off FreeSign servers.
• You want an independent OpenTimestamps proof on top of an RFC 3161 timestamp.
• You are fine preparing the PDF elsewhere and only need a verifiable seal.
• You are cost-sensitive and do not need templates / bulk / SMS / admin console.

How to migrate a one-off NDA flow to FreeSign

1. Open the NDA PDF on your machine. Drop it into free-sign.com. The SHA-256 is computed in your browser.
2. Enter your email and full legal name, tick consent. Receive a 6-digit OTP. Type it in.
3. Download the signed PDF — evidence JSON is embedded in the signature’s CMS, so there is one file to keep.
4. Optional: store that sealed PDF in your own Dropbox folder. You keep Dropbox as storage; FreeSign never became a second vault.
5. Open the signed PDF in Adobe Reader. A yellow ⚠️ trust warning is expected (AATL membership), not a broken signature. Check Signature Panel: document not modified, signed by your name.
6. Optional: verify outside Adobe with openssl cms -verify, pyhanko sign validate, and ots verify.
