How to merge PDFs
Drop or pick the PDFs (multiple allowed). The list order is the merge order—use the arrows to reorder. Click “Merge PDF” and the browser joins them locally and downloads the result. Password-protected or edit-restricted PDFs may fail to load.
FAQ
Does merging lose quality?
No. Pages are copied as-is, so quality matches the originals and total size is roughly the sum of the inputs.
Is my file safe? Uploaded?
Never uploaded. All parsing and joining happen in your current browser; files stay on your device.
