By Use Case: What to Pick

I just need a signature image for documents

Use the Signature Pad. Draw once, download PNG, reuse forever. Insert into Word docs, PDFs, emails, forms — anywhere an image goes.

I need to sign a specific PDF

Use a PDF Signer. Open the PDF in the tool, draw your signature on the page, download the signed PDF. One-step process.

I need someone else to sign a document

Use HelloSign (3 free/month) or PandaDoc (free e-signatures). Upload the document, add signature fields, send a link to the signer. They sign, you get a notification and a copy. These platforms provide audit trails.

I sign many documents every week

If you send 10+ documents per week for signatures, a paid platform (DocuSign, Adobe Sign, SignNow) is worth the cost for templates, reminders, bulk sending, and workflow automation. The free tiers on signing platforms do not scale to high volume.

Phone Apps vs. Browser Tools

Many people search for "signature app" expecting to install something from the App Store. Browser-based tools have advantages:

• No install: No storage used on your phone. No app updates.
• No permissions: Browser tools do not request access to your contacts, camera, or files.
• Cross-device: The same tool works on your phone, tablet, and computer.
• No account: Most signature apps require an email signup. Browser tools do not.

If you prefer a native app, Autograph and SignEasy have decent free tiers. But for most people, a browser tool does the job without the overhead.
