Merge your PDFs into one — right in your browser

Drop the files, drag them into order, download one PDF. Nothing is uploaded.

Combining PDFs without uploading them

Merging is usually the last step before something gets sent somewhere that matters — a signed contract joined to its appendix, scanned receipts collected for an expense claim, a set of certificates going to an employer. The files are assembled precisely because they are about to be shared, which makes uploading them to a conversion site first an odd risk to take.

MergeFit assembles the document inside your browser tab. Each PDF is read locally, the pages are copied into a new file, and you download the result. Nothing is transmitted and nothing is stored.

Order, then export

Drop in as many PDFs as you need and drag them into the order you want before exporting — the sequence in the finished document is whatever you set on screen. Pages are copied across as-is rather than re-rendered, so text stays selectable, image quality is untouched, and the merged file is not re-compressed.

Frequently asked questions

Will merging reduce quality?

No. Pages are copied directly into the new file, so nothing is re-rendered or re-compressed along the way.

Are bookmarks carried over?

Not currently — outlines and bookmarks from the source PDFs are not brought into the merged document.

How many files can I merge?

Up to three per merge is free. A one-time purchase removes the limit and adds page picking plus sort and reverse.

Are my files uploaded?

No. Everything happens on your own device.
