## FAQ

### Does merging compress or alter the content?

No. Pages are copied into the new file as they are; content, page size and quality stay unchanged.

### Is there a size or file count limit?

There is no hard limit; it depends on your computer memory. PDFs up to a few hundred MB merge smoothly.

### Are my files uploaded to a server?

No. Everything runs locally in your browser via WebAssembly. Files never leave your computer and are discarded when you close the page.

### Do I need to sign up or pay?

No. The site is completely free, requires no account, has no usage limits and adds no watermarks.
