Why merging locally matters
Most “free” PDF sites upload your documents to their servers. That means your contracts, statements, and records sit on someone else’s machine, subject to their retention policy. localdobe is different: the merge runs inside your browser tab using the same technology (WebAssembly and modern JavaScript) that powers web apps like Figma. Nothing is transmitted, logged, or stored.

Frequently asked questions
Is this merge tool really free?
Yes. No watermarks, no page limits, no signup. The tool runs in your browser, so it costs us almost nothing to offer.
Are my PDFs uploaded to a server?
No. Merging happens locally in your browser using WebAssembly-era JavaScript. Your files never leave your device — you can even disconnect from the internet after the page loads.
Can I change the order of the files?
Yes. After adding files, use the arrows to reorder them before merging.
Is there a file size limit?
Only your device’s memory. Files in the hundreds of megabytes work on most modern computers.
