Frequently Asked Questions
Up to 30 files in a single merge. For more than that, merge in batches and then merge the results.
Yes. Use the up and down controls on each file card, or sort automatically by filename or size.
No. Pages are copied across without re-encoding, so the merged file matches the originals exactly.
No. Merging happens in your browser, so your documents stay on your device.
Privacy and security
Your file is read directly from your device and processed in your browser. It is never uploaded to a server, so there is no copy for us to keep, share or lose. Closing the tab discards everything. If you want to check this yourself: open your browser’s developer tools, switch to the Network tab, and use the tool — you will see no request carrying your file or input leave the page.
