FAQ
Are my PDFs uploaded to your servers?
No. Merging runs in your browser using pdf-lib. Your files are not sent to us for processing.
Is merging free?
You can merge and download for free; some deployments add a short wait or an optional paid instant download.
Do I need an account?
No signup is required.
What are the limits?
By default, up to 50 files and 100 MB combined (see the project limits in our documentation). Very large PDFs may fail in the browser due to memory.
