Merge PDF in the order you choose

By ShinobiTools Team · Last updated: August 2026

Drop your PDFs in, put them in the right order and get one combined file back. No account, no watermark, and everything is deleted afterwards.

The order is the whole job

Merging PDFs is trivial; merging them in the right order is the part every tool gets wrong. Here every file you add appears in a list with arrows, so you put the contract before the appendix and the cover letter before both — and the list shows the size of each part, which is usually enough to tell two similarly-named files apart.

Up to 20 files go into one merge. More than that? Merge in batches: the result of the first batch is itself a PDF you can feed straight back in with the next twenty.

The pages come through untouched: nothing is re-rendered, recompressed or rescaled, so text stays as sharp as it went in and signatures stay where they were. If the result feels heavy, run it through the compressor afterwards.

What it does with your files

Your PDFs are uploaded, merged, and the originals are deleted from the server the moment the merged file exists. The merged file itself stays available for 45 minutes so you can download it, and is then deleted automatically. Nothing is stored, shared or used for anything else.

There is no account, no watermark and no daily cap. Everything runs on our own servers; the ads on the page keep them online. Your original upload is deleted the moment processing finishes, the cleaned result stays available for up to 45 minutes so you can download it and is then deleted automatically, and nothing is ever sold, shared or used to train AI.

Common questions

How do I combine PDF files into one?

Drop them onto the box above, set the order with the arrows and press Merge. You get one PDF with all the pages in your chosen order.

Is it free? Is there a watermark?

Free, no watermark, no account and no daily cap.

How many PDFs can I merge at once?

Up to 20 per merge. For more, merge in batches — the result of one merge can go straight into the next.

Does merging reduce the quality?

No. Pages are copied into the new file as they are, not re-rendered, so text and images stay exactly as sharp as in the originals.

Can I merge password-protected PDFs?

No — remove the password first in the app that knows it, then merge the unlocked copies.

Can I change the order of the files?

Yes, that is the point of the list: the arrows next to each file set the order, and the merge follows the list top to bottom.

What happens to my files?

Originals are deleted the moment the merge is done; the merged file is deleted automatically 45 minutes later.
