What's the difference between Personal and Studio?

Personal ($39) is for one person — unlimited use on one active device at a time. Activate on a new device and the old one signs out. Studio ($199) is for teams and commercial client work — unlimited team members, early access to new tools, and a commercial license.

Do I need an account?

No. Use any tool free up to 5 times per day on compute-heavier tools, and unlimited on lightweight ones. No card, no account, no signup required.

Where are my files processed?

Right on your device. Files never upload to any server. Everything runs in your browser — you can verify in DevTools → Network.

What happens if I use my Personal license on a second device?

The new device activates and the old device signs out. Your license key stays the same — you just move it between devices as needed. No limit on how often you switch.

Does this work on my phone?

Yes. Every tool works on iPhone, Android, tablet, and desktop.

What if I want a refund?

30-day money-back guarantee on both tiers. No questions asked. Email sales@cipherforces.com.

Will you add more tools?

Yes. New tools ship regularly. Your license includes every tool we ever release — Studio members get early access.

About Sign PDF.

Sign PDFs for Free — No Per-Envelope Fees

CipherForces PDF Signer lets you draw, type, or upload your signature and place it on any PDF document. The signed PDF is a standard file you can email, print, or upload anywhere. There are no per-envelope charges, no monthly limits, and no branding on the output.

DocuSign charges $10/month for 5 envelopes. Adobe Sign starts at $13/month. HelloSign gives you 3 free documents per month. CipherForces has no limits — sign as many PDFs as you need, forever.

Common Use Cases

Contracts and agreements: Sign freelance contracts, vendor agreements, NDAs, and lease agreements without printing.
Government and legal forms: Sign tax forms, court filings, permit applications, and notarized documents digitally.
School and HR paperwork: Sign permission slips, offer letters, onboarding forms, and policy acknowledgments.
Real estate: Sign purchase agreements, inspection reports, and disclosure forms from your browser.

Key Features

Three signature methods: Draw with your mouse or finger, type your name in a signature font, or upload an image of your handwritten signature.
Reusable .sig config files: Save your signature configuration and reload it on your next visit — no need to re-draw every time.
Multiple signatures per document: Place signatures, initials, and dates on different pages of the same PDF.
Legally valid: Electronic signatures created with this tool meet the requirements of the ESIGN Act and UETA for most use cases.
No branding: The output PDF contains your signature and nothing else — no "Signed with..." watermarks.
