SimplePDF vs ComPDFKit
You're paying for a multi-platform SDK when all you need is web-based PDF editing. SimplePDF gives you transparent pricing, instant integration, and privacy by default.
ComPDFKit is a PDF SDK vendor offering cross-platform support across Web, iOS, Android, Windows, C#, C++, and Python. They provide both annual subscriptions and perpetual licenses with quote-based pricing.
Enterprise PDF SDKs typically start at $25,000/year. SimplePDF starts at $99/month.

Do you need every feature?
Most teams embedding PDF editing need four things: text, signatures, form fields, and page manipulation. If that's you, ask yourself why you're paying for Office document conversion and multi-platform SDKs you'll never deploy.
What SimplePDF gives you
- Text, checkboxes, images, and signature fields
- Form field detection
- Page manipulation (merge, reorder, rotate, delete)
- Webhooks and email notifications
- BYOS: bring your own S3 or Azure Blob Storage - documents are uploaded directly from the browser to your storage
- Full white-labelling: custom logo, loading animation, hide the sidebar entirely, and choose which tools to show
- No server setup required - runs entirely in the browser
- Works anywhere: iframe-based editor that loads in any website, framework, or platform
Features most teams never use
- PDF conversion (to/from Office formats)
- Batch processing
- Native mobile SDKs (iOS, Android)
- Desktop platform support (Windows, C#, C++)
- Perpetual license option
Where SimplePDF shines
Zero server setup required
ComPDFKit's server features require your own infrastructure. SimplePDF is an iframe-based editor that runs entirely in the browser. No SDK configuration, no server setup, no deployment headaches.
Trusted by 100,000+ users
SimplePDF is used by over 100,000 people. Clean, intuitive, battle-tested. You're embedding a polished product your users already know.
Transparent pricing, no sales calls
ComPDFKit requires contacting sales for pricing. SimplePDF starts at $99/month, visible on the website. No procurement cycle, no surprise invoices.
Client-side only, by design
Documents never leave the browser. With BYOS, documents upload directly from the browser to your own S3 bucket or Azure Blob Storage - they never transit SimplePDF servers. No server-side processing needed. GDPR-friendly by design.
AI-assisted human-in-the-loop workflows
Legacy PDF SDKs were built for humans clicking buttons alone. SimplePDF combines AI-powered automation with human review, letting your users work faster while keeping full control over every edit.

Common questions
Can I migrate from ComPDFKit to SimplePDF?
Yes. SimplePDF is an iframe-based editor that loads in any website or framework. The React component and script tag are convenience wrappers around the same iframe. No SDK swap needed - most teams integrate in under an hour. See the getting-started guide. Your existing PDF documents work as-is.
What if I need PDF conversion?
If you need to convert PDFs to/from Office formats, ComPDFKit is the better fit. SimplePDF is purpose-built for PDF editing in the browser and includes OCR capabilities.
How does pricing actually compare?
ComPDFKit uses quote-based pricing - contact their sales team for specifics (compdf.com/pricing). SimplePDF starts at $99/month ($990/year) with no contract, and includes a free tier with no usage limits.
Is SimplePDF enterprise-ready?
SimplePDF serves businesses of all sizes with BYOS storage (S3 and Azure Blob Storage), webhooks, and full white-labelling (custom logo, hide sidebar, choose which tools to show). It's focused on web-based PDF editing rather than multi-platform document processing.
