Merge · In your browser
Two become one. Both stay yours.
Falcon Merge is a PDF combining tool that runs entirely on your computer. Pages from each input are copied at full fidelity into a single output; source metadata is dropped on save. The originals stay where you opened them.
The originals stay open on your computer through the whole process. The combined file lands where you started. By design.

Why this tool exists
Every online PDF merger asks the same thing: hand us the originals, we’ll hand back the combination. The price of the merge is the surrender of the inputs. Two confidential drafts, two NDAs, two halves of an offer letter — for the convenience of a single output, both go up to a server that has no reason to forget them.
A merger that runs on your computer doesn’t ask for the originals. The two files open in this tab, the pages are copied into a single new document, and the result is written here. Nothing left over, nothing left behind, nothing left elsewhere.

FAQ
Common questions
Do my files upload anywhere when I merge them?
No. Both PDFs open inside this browser tab, the pages are copied into one new document, and the combined file is written back here. There is no upload endpoint — open your browser network panel while you merge and the only requests you will see are the ones serving the page.
Is there a limit on how many PDFs I can combine?
There is no fixed cap. You can add as many files as your device's memory comfortably holds, because the merge runs on your computer rather than on a server. The ceiling is your own RAM, not a quota we impose.
Can I set the order of the files before they are combined?
Yes. Arrange the files in the order you want before you merge; the output follows that order exactly, first page to last. The reordering happens on your device, the same as the merge.
Will combining the files lower their quality?
No. Pages are copied across intact — text stays selectable, images keep their resolution, and form fields are preserved. A merge re-stitches the documents into one; it does not re-compress or flatten them.
Does the merged file keep links and form fields?
Page content, internal links, and form fields carry over into the combined document. Document-level bookmarks from the source files may not all survive, because the result is a brand-new file — check the output if bookmarks matter to your workflow.

Metadata stripped
Authors, edit history, EXIF, and embedded thumbnails are removed alongside the visible content.

What you remove is removed. Pages drop and the survivors stitch back into one file, all in the same tab.
Falcon Extract Pages
pdf.falcon.enterprises/extract-pages
Take what you need, leave nothing behind. A short PDF pulled from a long one, in the order you list.
Falcon Organise
