Frequently Asked Questions
Is my PDF uploaded to your server?
No. All processing happens in your browser using JavaScript. Your PDF file never leaves your device, ensuring complete privacy and security.
What makes SplitPDF different?
Unlike competitors that require file uploads, SplitPDF offers bookmark-intelligent splitting, size-based splitting for email attachments, and 100% client-side processing.
Is there a file size limit?
The limit depends on your browser's memory capabilities. Most browsers can handle PDFs up to 100MB comfortably. Larger files may take longer to process.
Is SplitPDF free?
Yes! SplitPDF is completely free with no registration, limits, or hidden fees. Split as many PDFs as you need.
Can I split password-protected PDFs?
Currently, SplitPDF works with unencrypted PDF files. If your PDF is password-protected, you'll need to remove the password first (using the password) before splitting. This ensures maximum compatibility with browser-based processing.
What browsers are supported?
SplitPDF works on all modern browsers including Chrome, Firefox, Safari, and Edge. For best performance, we recommend using the latest version of your browser. Mobile browsers are also supported, though large files may perform better on desktop.
