Frequently Asked Questions
Are my PDF files uploaded to your servers?
No. All PDF merging runs client-side inside your web browser using WebAssembly and pdf-lib. Your confidential documents never leave your computer.
Can I reorder the pages or files before merging?
Yes. You can drag or arrange the uploaded PDF files in the exact order you want them appended before generating the merged file.
Is there a limit on how many PDFs I can combine?
There is no artificial file count or size limit. Since processing runs on your local CPU and memory, you can merge as many documents as your device can handle.
