Merge PDF combines several PDF files into a single document, in whatever order you choose. Unlike compression tools, merging is completely lossless — each page is copied exactly as it was, so text remains selectable and searchable and image quality is preserved.
The whole process runs inside your browser. Your PDFs are never uploaded to a server, which makes this safe for contracts, statements, scanned IDs and anything else you would rather not send to the cloud. Drop in two or more files, drag them into order, and download the combined PDF.
Frequently asked questions
Is merging PDFs free?
Yes — it is completely free, with no sign-up, no watermarks and no limit on how many files you combine.
Are my PDFs uploaded to a server?
No. Everything happens locally in your browser, so your files never leave your device. Even confidential documents are safe to merge.
Does merging reduce quality?
No. Pages are copied as-is from each source PDF — text stays selectable and images are untouched. If you instead need a smaller file, use the Compress PDF tool.
How do I reorder files before merging?
Use the ▲ and ▼ arrows on each file card to move it up or down. Files combine top to bottom in the order shown.
