Frequently asked questions
Are my files uploaded to a server?
No. Every tool runs entirely inside your browser using JavaScript and WebAssembly, so your files never leave your device. Nothing is uploaded, stored, or sent anywhere.
Can I control the order of the pages and files?
Yes. Every page appears as a thumbnail. Drag pages to reorder them across files before merging, and use the rotate and delete buttons to fine-tune the result.
Is there a limit on how many PDFs I can combine?
There is no fixed limit. You can merge as many files as your device's memory allows; very large files may be slower on older phones.
Will the original formatting be preserved?
Yes. Pages are copied as-is, so fonts, images, and layout stay exactly the same in the merged file.
