Frequently asked questions
- Is there a limit on how many files I can merge?
- There is no fixed limit. Very large batches use more memory because the work happens on your device, so extremely large jobs may be slower on low-end phones.
- Are my files uploaded?
- This runs entirely in your browser — the file is never uploaded to a server.
- Will the quality change?
- No. Pages are copied as-is into the new document without re-compression.
