From HelloSign to Dropbox Sign
HelloSign was a well-regarded standalone e-signature tool before Dropbox acquired it in 2019. Since the 2022 rebrand to Dropbox Sign, the product has become increasingly integrated with the Dropbox ecosystem. Users who rely on Dropbox for file storage benefit from the tight integration. Users who don't use Dropbox may find the platform adds unnecessary complexity.
Privacy: No Third-Party Cloud Involved
When you use Dropbox Sign, your documents pass through Dropbox's cloud infrastructure. SigPDF takes a fundamentally different approach — your PDF is processed in your own browser using client-side JavaScript. There is no cloud upload, no server-side storage, and no third-party access to your documents at any point.
When Dropbox Sign Is the Better Choice
- You already use Dropbox and want documents stored there automatically
- You need to collect signatures from external parties
- You send the same documents repeatedly using templates
- You want detailed audit trails for each signing event
When SigPDF Is the Better Choice
- You need to sign your own documents quickly and privately
- You don't use Dropbox and don't want to
- Cost matters — €2.08/month vs $15/month
- You want your documents to stay entirely on your device
