Why Sign PDF runs great in Chrome
Chrome's V8 JavaScript engine and its strong WebAssembly support are exactly what a browser-based PDF tool needs. ContinuePDF leans on both to sign your PDF at near-native speed inside the tab — no extension required, because everything the tool needs is already part of the page.
Avoiding an extension matters for more than convenience. Extensions request permissions, can slow the browser down, and are one more thing to keep updated and trust. ContinuePDF asks for none of that: open the page in Chrome, sign your file locally, and download signed PDF. Your document is processed on your device and never uploaded.

Pro tip
Draw your signature slowly on a trackpad or touchscreen for a cleaner line, or upload a photo of your ink signature on white paper for the most authentic look. Size it to match the signature line rather than dropping it in oversized.
Frequently asked questions
Is a signature added this way legally valid?
In many places an electronic signature is acceptable for everyday agreements, but requirements vary by country and document type. For high-stakes legal documents, check what your jurisdiction or the other party requires.
Can I place the signature exactly where I want it?
Yes. You position and resize the signature freely, so you can drop it precisely on the signature line and add a date next to it if needed.
Do I need a Chrome extension to sign PDFs?
No. Sign PDF works as a regular web page in Chrome — there is no extension to install. Just open the tool, add your PDF, and download signed PDF.
Is Sign PDF fast in Chrome?
Yes. It uses Chrome's V8 JavaScript engine and WebAssembly to process your PDF at near-native speed right in the tab, so most jobs finish in seconds.
Is ContinuePDF free to use?
Yes. ContinuePDF and all of its tools, including Sign PDF, are free with no signup required. Because documents are processed in your browser rather than on our servers, we can offer the full feature set at no cost.
