Papyx
Merge PDFs without uploading a thing
Papyx puts your documents end to end in the order you decide and hands back a single file. The operation is structural: pages are copied across as they are, never re-rendered.
In practice that means text stays selectable, links stay links, and vectors stay crisp at any zoom. A PDF merged by Papyx weighs neither more nor less than the sum of its parts.

Merge PDFs offline, with no loss
-
Add your PDFs
Drop them all at once; they stack up in the document list.
-
Put them in order
Rearrange the list by dragging. That order is the order of the final document.
-
Merge
One click, and Papyx copies each document's pages in after the last.
-
Chain or save
The result can feed straight into another tool — page numbers, a watermark — without a round trip through the disk.
Worth knowing
-
No re-encoding
Merging copies the PDF's own objects; nothing is rasterized, so nothing is degraded.
-
Explicit order
The order is the one on screen, not a filename sort guessed on your behalf.
-
As many files as you like
The whole batch runs as one job, with a progress bar and a cancel that actually answers.
-
Chainable
The merged PDF becomes the next tool's source without being saved first.
Limits
-
A password-protected PDF cannot be merged: merging goes through pdf-lib, which does not decrypt.
-
Form fields from different documents may share a name; Papyx does not rename them.
Questions about “Merge”
Does merging reduce quality?
No. Pages are copied at the level of the PDF's structure — nothing is rendered to an image, so text stays text and vectors stay vectors.
Is there a limit on how many files, or how large?
None imposed by Papyx — no account, no quota, no queue. The work happens inside the app, on your machine.
Can I merge a password-protected PDF?
No. Passwords are only accepted by the tools that go through the rendering engine: PDF → Images, Compress and Extract text.
