Merging...
PDF merged successfully!
Up to 10 files with a combined size of 50 MB or less. There is no limit on the page count of individual files, and each file shows its page count in the list before you merge.
Drag any file row to a new position in the list; files are merged top to bottom exactly as shown. You can also remove a single file with the remove button on its row, or clear the whole list and start over.
No. Pages are copied directly into the new document without re-rendering or recompression, so text, images, and vector graphics keep their original quality regardless of how many files you combine.
Encrypted or password-protected files cannot be read by the merge library, so they fail with an error notice. Unlock the file first, then add it to the list again.
Never. Merging runs fully client-side with pdf-lib: files are read into browser memory, combined there, and the result is downloaded directly. Nothing is uploaded or stored anywhere.
