Is there a limit to how many PDFs I can merge?

You can combine multiple files at once. Typically, you can select up to 20 files for a single merge operation.

Will the order of my pages be preserved?

Yes! You have full control over the sequence. Just drag the thumbnails into your preferred order before merging.

With SignSurio, yes. Because the merging happens locally in your browser (not on a server), your data remains totally private.
