How it works
How merges are counted
One merge = one click of the Merge PDFs button, no matter how many files are in that batch. So the limits are more generous than they sound.
One merge, many files
Merging 20 invoices into a single PDF counts as one merge. On the Standard plan you can do that thirty times, which is 600 PDFs in total. On Pro it is 5,000.
Free refills monthly
The three free merges reset on the 1st of every month, so the free plan never locks you out permanently. If you only merge something occasionally, you may never need to pay at all.
What counts against the file limit
The file limit is per merge, not per month. A batch of 8 files needs a plan that allows at least 8 files per merge — Standard (20) or Pro (50).
Very large files
Because everything happens in your browser, memory is the real ceiling. If a batch is unusually large the tool warns you first and suggests merging in smaller groups, instead of failing silently.
Activation
Three steps, about a minute
Buy and check your inbox
The payment provider emails a licence key to the address you use at checkout. Keep that email — it is your proof of purchase.
Paste the key once
Enter it in the box below or on the tool page. There is no sign-up form and no password to remember.
Merge as much as your plan allows
The key is stored in your browser, so the tool stays unlocked on that device. You can paste the same key on your other devices.
Already bought a licence?
Your licence is active on this device. Happy merging!

FAQ
Licensing questions
Is this a subscription?
No. The free plan costs nothing, and both paid plans are one-time payments. There is no renewal date, no recurring charge and no per-file fee.
How is a merge counted?
One merge means one click of the Merge PDFs button, however many files are in that batch. So a Standard licence's 30 merges can combine up to 600 PDFs in total, since it allows 20 files per merge.
Does the free plan refill?
Yes. The free plan includes 3 merges every month and the allowance refills on the first of each month, so you are never permanently locked out.
What happens if a batch is bigger than my plan allows?
Nothing is charged and nothing is uploaded. The tool tells you which limit you hit and lets you remove files or merge in smaller groups. You can also activate a bigger licence at any time.
Do I need to create an account?
No account is needed. Your purchase produces a licence key which you paste into the tool once. The key is stored in your browser, so the tool opens unlocked on that device from then on.
Can I use one licence on several devices?
Yes, a licence covers the devices you personally use, such as your laptop and your phone. It is not for redistribution or for embedding in another product.
What is the refund policy?
If the tool does not do what you needed, email us within 14 days of purchase and we will refund you in full. You do not have to explain why.
