Best Free PDF Signing Tools in 2026
If you just need to sign a PDF and send it back, a free online signer is faster than installing an app. The best one for you depends on whether you want typed, drawn, or image-based signatures and whether you'll sign multiple pages.
At-a-glance comparison
| Tool | Pros | Cons | Best for |
|---|---|---|---|
| MyPDFKitty | Type, draw, or upload a signature; place on any page; no watermark. | Doesn't yet support multi-party signature workflows. | Personal contracts, forms, and one-off signing. |
| Smallpdf eSign | Familiar UX. | Free tier limits per day; some features paywalled. | Light, occasional signing. |
| DocuSign Free Trial | Industry-standard for legal e-sign. | Free tier is a 30-day trial, not a permanent free plan. | When you need an eIDAS-grade legal trail. |
Pricing and feature data on competing tools changes often. Verify on each provider's site before purchasing.
