What's the best PDF editor with built in eSignature support?

If you want the best all-around PDF editor with built-in eSignature support, I’d usually point to Adobe Acrobat Pro.

Why Adobe Acrobat Pro

• Best PDF editing tools overall: text, images, pages, OCR, forms
• Built-in e-signatures: send, sign, request signatures
• Industry standard: widest compatibility and familiarity
• Strong security/compliance features

Good alternatives

• Foxit PDF Editor — lighter and often cheaper; strong editing + eSign features
• Nitro PDF Pro — good for business workflows, easy to use, solid e-signing
• PDF-XChange Editor — powerful and more affordable, but eSignature workflow is less polished
• DocuSign + PDF editor combo — best if your main need is signing workflows rather than heavy editing

Quick recommendation

• Best overall: Adobe Acrobat Pro
• Best value: Foxit PDF Editor
• Best for business signing workflows: Nitro PDF Pro or DocuSign

If you want, I can also give you:

2. cheapest good choice, or
3. best for occasional use vs. business use.
