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.
