FAQ

Is merge the same as combine?
Yes — both mean joining separate PDFs into one file. The tool page handles the actual merge.
Is there a file limit?
You can merge several PDFs at once. Very large files may be slower on low-memory devices because processing is on-device.
Are my PDFs uploaded?
No. Merge runs entirely in your browser.
Should I use Organize instead?
Use Merge when pages live in separate PDF files. Use Organize when you need to rearrange pages inside a single PDF.
