Frequently asked questions
Can I merge PDFs of different sizes and orientations?
Yes. The merged PDF will combine all pages as-is, preserving their original size and orientation. Mixed portrait and landscape pages work fine in one document.
Is there a limit to how many PDFs I can merge?
You can merge up to 20 PDFs at a time, with a total combined size limit of 100 MB. If you need to combine more, merge them in batches.
Are my PDFs uploaded to a server?
No. All PDF merging runs locally in your browser. Your files are never uploaded, stored, or accessible to anyone but you.
Processed in your browser
Your PDF is processed entirely in your browser. It is never uploaded to any server, and we cannot see or access your files.
