How Merging PDFs Locally Works
Client-Side PDF Merger & Combiner runs entirely in your browser with JavaScript. There is no sign-up, and whatever you type or open here is processed on your device instead of being sent to a server.
Combine PDF Files Locally, Without Uploading Them
Many online PDF tools upload your files to a server to process them. This merger runs entirely inside your browser with client-side JavaScript, so there is no upload wait and no copy of your documents on someone else's server.
Combine PDF Documents Free Without Sign-Up or Watermarks
Add your files, put them in order with the ↑ and ↓ buttons and merge them into one PDF, with no account, no page limit and no watermark.
Safe PDF Combination for Confidential Legal and Financial Files
Legal agreements, bank statements, tax returns, and medical records call for care. Merging them on your device means they are never sent to a server, which lowers the risk; still follow your organisation's own rules for confidential files.
Line Up Every Attached File Before Combining
Each file in the list shows a small picture of its first page and its page count, so you can check the order before merging. If one attached file came out of the scanner sideways, its ↺ or ↻ button turns that whole file to match the others, and Preview lets you page through the combined PDF before you save it.
What Content is Preserved in the Merged PDF?
Pages keep their text, images, vector graphics and page sizes, in the order you set. Bookmarks, form fields and digital signatures from the original files may not survive merging, so keep the originals.
Why processing in your browser matters
Many online tools upload your files or text to a server to process them. This one does the work on your computer or phone, so your data is not sent to us or stored anywhere else. That lowers the risk when you work with confidential material, although you should still follow your organisation's own rules. Read how this works in our Privacy Policy.
