How to use MergeFit

Combine many PDFs into one

Drop your PDF files, drag to put them in the order you want, then merge — MergeFit stitches every file together in one pass and hands you a single PDF.

Reorder and pick pages

Drag files up or down before merging to control the order they land in the final PDF. Pro lets you pick exact pages from each file (for example “1-3, 5”), and sort or reverse the whole list in one click.

Your files never leave your device

Everything happens in your browser. No upload, no account, no size limits imposed by a server — your documents stay yours.

FAQ

Is it free?

Yes — merging up to 3 files is free forever. Pro (one-time) unlocks unlimited files per merge, plus page picking and sort/reverse.

Does it change the quality of my PDFs?

No — pages are copied as-is into the merged file, so nothing is re-rendered or re-compressed.

Are bookmarks kept?

Not currently — bookmarks/outlines from the source PDFs are not carried into the merged file.
