Why merge PDFs in your browser?
Most online PDF mergers upload your documents to a server. If those documents are contracts, bank statements or medical records, that's a real privacy risk. PDFMergely processes everything locally, your files are combined on your own device and never transmitted. It's faster too: there's no upload to wait for.
Combining months of statements for a mortgage, visa or loan application? See the dedicated guide to merging bank statements without uploading them.
Do this from your toolbar. The free PDFMergely browser extension merges PDFs without opening a tab, and it runs entirely on your device: no permissions, no uploads, and it works offline. Get the extension.
Frequently asked questions
Are my files uploaded anywhere?+
No. Merging happens entirely in your browser using your device’s own processing. Your PDFs are never uploaded, stored, or seen by us or anyone else.
Is it really free?+
Yes. Merging PDFs is completely free with no sign-up required.
Does it work offline?+
Yes. After the page loads once, the merge tool keeps working even without an internet connection, because all processing is local.
Is there a file size limit?+
PDFMergely does not impose an artificial file-size limit. Because processing happens locally in your browser, the practical limit depends on your device’s available memory and browser capabilities. Most everyday PDF documents process without difficulty.
What happens to my files after I close the tab?+
Nothing persists. Any temporary working data is cleared automatically, and because files were never uploaded, there is nothing on a server to delete.
