About auto-classify pdf

Identify the document type of any PDF — invoice, contract, receipt, ID, and more. It sits in the pdf & office shelf alongside 83 other pdf & office tools, needs no account, and keeps the same behaviour whether you open it here or call it through the REST API.

It takes a file in PDF and gives back JSON. It uses a model we host ourselves, not a third-party API. The work happens on our servers, and the upload is encrypted per file and deleted an hour later — 24 hours if you are signed in. The same operation is available programmatically at POST /v1/pdf/classify.

Auto-Classify PDF questions

Where does Auto-Classify PDF process my file?

On our own servers. This tool needs more than a browser tab can provide, so the file is uploaded over TLS, processed on our infrastructure — no third-party processing APIs are in the path — and both the input and the result are deleted within an hour.

Can I run Auto-Classify PDF on several files at once?

Yes. Auto-Classify PDF takes one file at a time, so selecting several runs it once per file, one after another, and you get a result for each.

Do I need an account to use Auto-Classify PDF?

No. Auto-Classify PDF works without signing in, and that is not a trial — it is how the free tier works. An account only matters for things that need one to exist at all: larger server jobs against your quota, API keys, saved workflows and billing.

Can I run Auto-Classify PDF from my own code?

Yes. Every tool on the site is reachable from the REST API with the same slug — `pdf-classify` — and the same options as this page, so anything you can do here you can automate against your own files.
