Every e-signature platform can get a signature on a PDF; the differences that matter are legal admissibility in the relevant jurisdiction, how deeply the tool embeds into the CRM or document system already in use, and per-envelope pricing once volume actually scales past a trial. This guide ranks on those three points rather than the signing experience alone, which is broadly similar across the category.
What it is: Electronic signature software lets documents be signed digitally with a legally binding signature, recording an audit trail of who signed what and when in place of a wet-ink signature.
DocuSign
United StatesThe most widely recognised e-signature brand, now a broader agreement platform
Near-universal recognition means recipients rarely hesitate to sign, which is a real, if hard to quantify, conversion advantage. Costs scale up faster than some competitors once envelope volume grows past a small business's typical usage.

Adobe Acrobat Sign
United StatesE-signature tightly integrated into the wider Adobe document ecosystem
The tightest option for a company already standardised on Acrobat and the broader Adobe Document Cloud for PDF workflows. Offers less advantage to a company with no other Adobe tools in its stack.

PandaDoc
United StatesE-signature bundled with proposal and quote document creation
The document-building and CRM-integrated proposal workflow is a genuine step beyond pure signature capture, useful for a sales team sending quotes regularly. Less relevant for a legal or HR team that just needs signatures on finished documents.

Dropbox Sign
United StatesStraightforward e-signature with a clean API for developers
A genuinely clean API that developers consistently rate as easier to work with than DocuSign's, which matters for a company embedding signing into its own product. Fewer advanced workflow features for a large enterprise's complex approval chains.

signNow
United StatesBudget e-signature aimed at small businesses and teams
One of the lowest-priced genuinely reliable e-signature tools, a sensible choice for a small business signing a modest volume of documents monthly. Enterprise-grade integrations and admin controls trail DocuSign and Adobe Sign.

SignRequest
NetherlandsEuropean e-signature provider with strong eIDAS compliance
Particularly relevant to a European business wanting EU-based data residency and clear eIDAS compliance documentation. Now owned by Box, worth checking its current roadmap as a standalone product before a long-term commitment.

eversign
GermanyE-signature with a genuinely usable free tier for very low volume
The free tier is generous enough for a small business signing only a handful of documents a month to never need to upgrade. Integration marketplace is considerably smaller than the category leaders'.
Free tier for limited documents, paid tiers beyond
