100% free • Works offline in your browser • No file uploads to servers
Nothing to install — the online merge tool loads in Chrome, Safari, Edge or Firefox on any operating system.
Choose PDFs from Windows, macOS, ChromeOS, Android or iOS; the browser file picker handles all of them.
Your merged PDF downloads instantly to the same device you are working on.
Desktop PDF suites cost money, need updates and are usually blocked on managed computers. An online merger loads in a second, works the same on every operating system and leaves nothing behind when you close the tab.
Because this particular tool processes files locally, you get the convenience of a web app without the privacy trade-off that normally comes with uploading documents to someone else's server.
Any browser released in the last few years supports the WebAssembly and File API features the merger relies on. Once the page has loaded, you can even lose your internet connection and the merge will still finish.
No. Everything runs in the browser tab, so there is no installer, no extension and no admin rights needed — useful on work or school computers.
Yes. On Android and iPhone you can pick PDFs from Files, Drive or Downloads and the merged file lands in your device's download folder.
Yes. Only the page itself is downloaded once; the merge happens locally, so a 200 MB job costs no upload bandwidth at all.
No server-side cap exists because nothing is uploaded. Very large jobs are limited only by the RAM available to your browser tab.
