Combine multiple PDFs into one. Reorder by file or page, rotate, duplicate — then merge in one click.
About This Tool

FAQ
Frequently Asked Questions
Is it safe to merge PDFs online?
Yes. Everything happens in your browser — your files never touch our servers.
What is Files view vs Pages view?
Files view: drag entire documents. Pages view: drag individual pages across all documents.
Can I add more files after uploading?
Yes. Both views have an 'Add File' button to load additional documents at any time.
How many files can I merge at once?
Up to 20 files at once — limited only by your device memory, not by our tool.
Will merging reduce quality?
No. Pages are copied byte-for-byte using pdf-lib. Text, images, and formatting are fully preserved.
