KEEP
Bookmarks · metadata · forms
Bookmarks merge into a unified outline. Form fields keep their names. Metadata from the first file becomes the merged file's metadata.

ENCODE

What it actually does
01 · DROP
Any number of PDFs
Two PDFs, ten PDFs, fifty PDFs — drop them all. No daily cap, no per-merge file count limit, no premium gate.
02 · REORDER
Page-level drag
Page thumbnails appear after the drop. Drag any page to any position. Drop pages you don't want with one click. The freemium sites gate this; Morph doesn't.
03 · KEEP
Locally rebuilt
pdf-lib stitches the merged document in your browser tab and hands you the file. Originals never leave your machine.
How it works
- Open morph.cool in any modern browser. No install, no account, no card.
- Drop two or more PDFs onto the drop zone. Drop a folder if you want.
- Drag thumbnails to reorder pages or whole files. Click × on any page you want to drop.
- Hit merge. pdf-lib rebuilds one combined document in your browser tab.
- Download the merged file. Originals stay on your machine, untouched.
Why PDF mergers feel like a tax
The freemium PDF sites turned PDF tools into a category and then turned the category into a freemium funnel. All of them upload every byte to their servers — fine for a one-page invoice, painful when the PDF contains attorney-client privileged text, employment offer letters, medical records, or the unsigned-contract version of a deal you haven't announced. The rest run the same playbook: server-uploads, file-size caps, daily limits, ads on the wait page. Morph runs pdf-lib in your browser tab and removes every part of that loop. Same merge math, no upload, no cap, no queue.
Where a document-automation service still wins
The freemium PDF sites' mobile apps, cloud-storage integrations, and bulk operation APIs for enterprise document pipelines are mature — if you're running a document automation workflow that pulls files from cloud storage and stamps them through OCR plus merge plus signature, that's a different product than this one. Morph is the daily-driver browser version for everyone else who just needs to combine three PDFs without uploading them anywhere.
Frequently asked
What about the hourly quota on the freemium sites?
The freemium PDF sites cap the free tier at two PDF operations per hour and upload every file to their servers. Morph runs pdf-lib locally in your browser tab — no upload, no hourly quota, no daily file count cap.
How is this different from the freemium PDF sites?
Morph runs locally — no file size cap beyond your machine's memory, no premium gate on reorder, no ads, no queue.
How many PDFs can I merge?
As many as your machine's memory holds. Most laptops can comfortably merge fifty PDFs at a time. Morph never imposes an artificial cap.
Can I reorder pages, not just files?
Yes. Page thumbnails appear after you drop the files, and you can drag any single page to any position in the merged output. The freemium PDF sites gate this behind Premium; Morph is free for everyone.
Will text, links, and form fields still work?
Yes. pdf-lib preserves text, vector shapes, hyperlinks, embedded fonts, form fields, and annotations from each source PDF when it builds the merged file.
Are my PDFs private?
Yes. The merge happens in your browser tab. Originals never leave your machine, the merged copy downloads locally, and nothing persists once you close the tab.
