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.

FAQ

Frequently asked questions.

How do I sign a PDF online for free?

Open the Sign PDF tool, load your PDF, then either draw your signature with a mouse or finger or type it in a signature font. Place it where you want on the page, then download the signed file. No signup is required and the tool is free.

Is my PDF uploaded to a server when I sign it?

No. The Sign PDF tool runs entirely in your browser using JavaScript, so your document never leaves your device or uploads to any server. Everything happens locally on your computer or phone, which keeps your contracts and private documents fully under your control.

Can I draw my own signature instead of typing it?

Yes. You can draw a freehand signature directly on the page using a mouse, trackpad, or touchscreen, which is useful on phones and tablets. If you prefer, you can type your name and have it rendered as a signature instead. Both options are built into the tool.

Does signing a PDF in the browser require an account or installed software?

No account, login, or installed software is needed. The Sign PDF tool loads in any modern browser and works without registration. Because the signing happens client-side, you can use it for free without creating a profile or downloading a desktop application first.
