Merge PDF — FAQ
You
How many PDFs can I merge at once?
PixelDocs
There is no fixed limit — add as many files as your browser can comfortably hold in memory. For very large sets of scanned documents, merging in smaller batches gives the best performance.
You
Will merging change my PDF quality?
PixelDocs
No. Pages are copied into the new document without re-encoding, so text, images, and fonts keep their exact original quality.
You
Can I change the page order before merging?
PixelDocs
Yes. Every file shows thumbnail previews that you can drag into any order, and you can drop files you no longer need.
You
Are my documents uploaded to a server?
PixelDocs
Never. Merging runs entirely in your browser, so sensitive documents never leave your device — no signup, no queues, no deletion windows to trust.
