What Is a Credit on NexaPDF AI?

Run a tool and it spends credits from your allowance. That's the whole idea — a credit is a count of work done, not a balance of money.

This matters because the word "credit" usually means store credit: cash you've loaded that gets drawn down. Credits here are nothing of the sort. They have no cash value, they can't be withdrawn or transferred, and they aren't a wallet. They exist so you can see what an allowance actually buys you, in the only unit that matters: how much you can do with it.

A tool's price reflects what it takes to run. Merging, splitting, rotating or reordering pages is cheap work on our own servers, and those tools sit at the bottom of the range. Anything that has to read your document with a language model — Chat with PDF, AI Summarizer, Translate PDF, Smart Redact — costs real money per document at an external provider, and is priced accordingly. Heavy local work like OCR, which rasterizes and recognizes every page, sits in between.

So the honest summary is: most everyday PDF tools are the cheapest thing on the site, and the AI tools are the expensive ones, with a spread of roughly twenty-five to one between the two ends.

You never have to guess, and you never find out by being charged. Every tool states its own price on the tool itself, in the credit counter beside the upload box, before you run anything — and the full list for all of them is on the pricing page.

Those figures live there rather than in this article because they're read live from the same configuration the server charges against — the pricing page can't go stale, and a number typed into a blog post can.

Credits are deducted before a tool runs, because that's the only way two simultaneous requests can't both spend your last one. If the run then fails for any reason, the credit is returned automatically.

That includes mistakes on your side, not just ours. Typing the wrong password on Unlock PDF returns an error — and your credit. Uploading a file the tool can't read does the same. You're charged for results, not attempts.

Free credits refill every day. Use them or don't; a fresh allowance arrives the next day either way. Guests get a smaller daily allowance than signed-in users, and it's counted per network rather than per person — so on a shared office connection, someone else may have already used some of it.

Credits on a paid pass work the other way: they're granted once, up front, and sit there until you spend them or the pass ends — whichever comes first. A pass is a one-time purchase, not a subscription: nothing auto-renews, there is no cancellation to remember, and no card is kept on file.

Passes aren't on sale yet — every tool is currently free for everyone on the daily allowance. The pricing page always shows the live position, so check there rather than taking this paragraph's word for it.

There's no single answer, because it depends which tools you use. The same allowance is a great many merges and rotations, or a much smaller number of AI runs. If you mostly do everyday PDF work, you will almost certainly never see the limit; if you're running AI over document after document, you'll feel it.

Two things are worth counting before you start. Some workflows are more than one run: Smart Redact scans for personal data, and then the redaction that acts on your confirmed list is a separate, much cheaper run — so budget for both halves. And a workflow that chains several tools together spends each step's cost, not one.

The current allowance for every tier, and the cost of each tool, are both listed on the pricing page.
