Merge PDFs Without Handing Them Over

Merging usually means uploading confidential documents to someone else's server. ModiFyX does it in the browser, so the files never leave your machine.

Any Number Of FilesCombine two PDFs or twenty, in whatever order you arrange them.
Quality UntouchedPages are copied, not re-rendered — text stays selectable and sharp.
Reorder Before MergingMove files up and down until the finished document reads correctly.
Confidential By DefaultContracts and reports are merged on your machine, never uploaded.
InstantNo upload wait, no queue, no file size ceiling.
Free ForeverNo watermark on the output and no daily limit.
