A lot of the tools that show up when you search for a free PDF merger are not actually free — they process your first file without charge, then ask for a subscription before you can download. Or they are free but add a watermark to every page of your output. Neither is useful when you just need to combine two documents quickly.
PDF2Tool's merger is free with no catches: no file count limits per session, no watermark on downloads, no account required. You can merge up to 10 PDFs at once, and the files are processed in your browser — nothing gets uploaded to a server unless you explicitly need it.
This is the tool to bookmark if you regularly combine PDFs for work — merging invoices before sending to accounting, combining a cover page with a report, attaching an appendix to a main document. It is a 30-second job and you do not need to install anything.
Need to do more after merging? If the resulting file is large, run it through Compress PDF Without Losing Quality. If your PDFs are password-protected, use Unlock PDF first. For school-specific merge workflows, see Merge PDF for School.
It is free. No watermarks, no file limits, no account. PDF2Tool makes money through optional premium features — the merger will always be free.
Up to 10 PDFs, each up to 25MB. For larger merges, split the job into two batches and merge the results.
Files are processed in your browser where possible. Any uploaded files are automatically deleted within 30 minutes.
