What people ask us
How many files can I merge at once?
We impose no cap. Several dozen documents pose no difficulty; the only limit is the memory available on your machine.
Does the result carry a watermark?
Never. The file produced on the free plan is identical to the one a subscriber gets. Our limits apply to volume and to certain features, never to the quality of the result.
Are my files stored anywhere?
No, because they never reach us. We know neither their names, nor their contents, nor their size: there is nothing to keep, and so nothing to delete.
Can I reorder pages before merging?
You can reorder whole files by dragging them. To rearrange pages inside a document, use the page organiser first, then come back here.
Can I add images to the merge?
Yes. JPG, PNG and WebP files are added like PDFs: each image becomes a page of the resulting document. You choose whether it keeps its original dimensions or fits an A4 or Letter page, in which case it is centred without being stretched or cropped.
Do I need an account?
No. Without an account you get three operations per day. A free account lifts that limit on most tools.
