Foxit SDK Alternative
Foxit is well-known for their desktop PDF editor and has built an SDK business alongside it. Their web SDK relies on server-side rendering: PDFs are rendered on your server and streamed to the client. This produces high-fidelity output for complex documents but requires deploying and maintaining server infrastructure. SimplePDF runs entirely client-side - no server, no rendering pipeline, no Foxit dependency.
What you get with SimplePDF
No server-side rendering
Foxit's web SDK renders PDFs on your server and streams the output. SimplePDF processes everything in the browser. No rendering infrastructure to deploy or maintain.
One-line integration
No SDK installation, no server setup, no rendering pipeline configuration. One iframe tag and your users have a full PDF editor.
Transparent pricing
Foxit uses quote-based pricing. SimplePDF starts at $99/mo with no annual commitment. You see the price before you talk to sales.
Client-side privacy
Because Foxit renders server-side, documents pass through your server. With SimplePDF, documents never leave the user's browser.

Does Foxit have a web PDF SDK?
Yes. Foxit offers a web SDK that renders PDFs server-side and streams the output to the browser. This provides high-fidelity rendering but requires deploying and maintaining server infrastructure.
Is Foxit PDF SDK client-side or server-side?
Foxit's web SDK uses server-side rendering. The PDF is processed on your server and the rendered output is displayed in the browser. This differs from SimplePDF's approach where the entire PDF is processed client-side in the user's browser.
What is a lighter alternative to Foxit for web PDF editing?
SimplePDF is a lighter alternative that runs entirely client-side. It embeds as a single iframe, requires no server infrastructure, and includes form filling, signatures, and white-label support. The trade-off is that server-side rendering may produce higher fidelity for very complex PDFs.
