Part of the Zerocoder platform
One tool of a platform where AI generates websites, images, video, text and documents — under one subscription.
A contract, its annexes, the invoice — the client expects one file, not a scatter of attachments. Merge joins up to ten PDFs in the order added: each document’s pages run consecutively, nothing shuffles. Result too heavy — run it through compression; drop extra pages with extraction; turn images into PDFs with the converter. All tools — in one section.
A deal packet as one file
The paperwork classic: contract + annexes + invoice. As separate files something always gets lost in the thread. Join them in reading order — contract first, annexes by number, invoice last — and send one file. Order follows the order you add them.
Scans and photos in the same packet
Turn a passport or receipt photo into a PDF with the JPG to PDF converter first, then add it to the packet. That's how a full bank or visa kit is built from a mix of scans, photos and ready documents.
Limits and page order
Up to ten files of 25 MB per run; pages inside each document keep their order, files follow the add sequence. Encrypted PDFs are skipped — remove passwords beforehand. Shrink a big result with compression.

FAQ
Is page order preserved?
Yes: files follow the order added; pages inside stay as in the sources.
How many files can I merge?
Two to ten per run, 25 MB each.
Can I reorder files?
Order follows the add sequence — add them in the order you want.
Do password-protected PDFs work?
No, encrypted ones are skipped — remove protection before merging.
The result is huge — now what?
Run it through the neighbouring “Compress PDF”.
Do I need an account?
Your first result needs no account. After that we ask for a free sign-up: signed-in users get 5 runs per day, and the Zerocoder Studio has no limits.
What happens to my files?
Nothing is stored: processing uses memory and temp files that are deleted immediately.
Do mixed page sizes work?
Yes, every page keeps its size — mixing A4 and letter is fine.
What else does Zerocoder do?
AI document, text and image generation, courses, jobs — the PDF utilities are one part of the Studio.
