About Merge PDF

Merging PDFs is the most common document chore there is: a contract plus its annexes, a batch of receipts for an expense report, chapters scanned separately that belong together. This tool combines any number of PDFs into one file, in the exact order you arrange them — drag the thumbnails to reorder before you merge. Page sizes and orientations are preserved as-is, and because the merge runs in your browser's memory, even large documents combine in seconds.

Frequently asked questions

Are my files uploaded anywhere?
No. Merge PDF runs entirely in your browser. Your files are read from your device, processed in memory, and never sent to any server.
Is there a file size or count limit?
There’s no hard limit — you’re only bounded by your device’s memory. Most people merge dozens of files with no trouble.
Is it really free?
Yes. Tools-Bench is free and supported by the ads you see around the tool — never by charging for the tool or selling your data.
