SigPDF vs HelloSign: Side-by-Side Comparison
HelloSign was acquired by Dropbox in 2019 and rebranded as Dropbox Sign. It focuses on multi-party signing workflows with integrations into the Dropbox ecosystem. SigPDF takes a fundamentally different approach — it is a browser-based tool that lets you sign PDFs locally on your device without uploading files to any server. Here is how they compare:
| Feature | SigPDF | HelloSign (Dropbox Sign) |
|---|---|---|
| Price | From €2.08/month (annual) | From $15/month (Essentials) |
| Privacy | Files never leave your browser | Files uploaded to Dropbox cloud |
| Account required | No | Yes |
| Free tier | Free to try (download requires subscription) | 3 signature requests/month |
| Multi-party signing | No (single signer) | Yes |
| Installation | None — works in browser | None — web and mobile apps |
| Watermarks | Never | None on paid plans |
| Templates | No | Yes (paid plans) |
| Audit trail | No | Yes |
Privacy: Your Documents Stay on Your Device
When you use HelloSign (Dropbox Sign), your PDF is uploaded to their cloud infrastructure. This is necessary for their multi-party signing workflow — other signers need to access the document remotely. However, it means your sensitive files pass through third-party servers and are stored there until the signing process completes and the retention period expires.
SigPDF works entirely in your web browser using client-side JavaScript. Your PDF is never transmitted to any server. This makes SigPDF the better option for confidential documents — contracts, financial records, legal agreements, and anything containing personal information you would rather not share with a third party.
Pricing: Significantly More Affordable
HelloSign's Essentials plan starts at $15/month (billed annually), and the Standard plan with team features runs $25/month per user. Enterprise pricing goes even higher. SigPDF starts at just €2.08/month when billed annually — a fraction of HelloSign's cost. If you need to sign PDFs yourself rather than manage multi-party signing workflows, SigPDF delivers the core functionality at a significantly lower price.
Simplicity: No Account, No Dashboard
HelloSign requires you to create an account, set up your profile, and navigate a dashboard before you can sign anything. With SigPDF, you visit the site, open your PDF, add your signature, and download. There is no registration, no email verification, and no learning curve. The tool does one thing — sign PDFs — and does it well.
When HelloSign Is the Better Choice
HelloSign excels when you need to send documents to multiple signers, use reusable templates, integrate with Dropbox or Google Workspace, or maintain detailed audit trails. It is a capable platform for teams and businesses that manage high volumes of multi-party signing. If your needs are simpler — signing PDFs yourself quickly, privately, and affordably — SigPDF is the better fit.
