Frequently asked questions

Is it safe to merge PDFs on yhile.com?

Yes. The PDF merger runs entirely in your browser. Your PDF files are never uploaded to any server.

How many PDFs can I merge at once?

There is no hard limit. You can add as many PDF files as needed. Performance depends on the total file size and your device.

Will the merged PDF preserve the original quality?

Yes. pdf-lib is used to copy pages directly, preserving all content, fonts, and images at full quality.

Can I change the order of PDFs before merging?

Currently PDFs merge in the order you add them. Remove and re-add files to reorder.
