Frequently Asked Questions

Is this really free?▼

Yes, completely free. No hidden charges, no watermarks, no file size limits. All processing happens locally in your browser.

Are my PDFs uploaded to a server?▼

No. Everything runs in your browser using WebAssembly. Your files never leave your device. This makes it 100% private and secure.

Is there a file size limit?▼

There's no set limit, but very large PDFs (500+ pages) may use significant browser memory. For most documents, this works perfectly.

Does merging preserve formatting?▼

Yes. The merge operation preserves all content, fonts, images, and formatting from each source PDF exactly as-is.

What browsers are supported?▼

Chrome, Firefox, Safari, Edge, and Opera — any modern browser with JavaScript enabled. Works on desktop and mobile.

Can I use this offline?▼

After loading the page once, the PDF processing library is cached by your browser. You can then use the tool without an internet connection.
