About barcode scanner

Upload a photo and read the barcode: EAN, UPC, Code 128, Code 39, ITF, Data Matrix, PDF417, Aztec and QR. Decoding happens in your browser — the image is never uploaded. It sits in the developer shelf alongside 76 other developer tools, needs no account, and keeps the same behaviour whether you open it here or call it through the REST API.

It takes any image and gives back JSON. The work happens in your browser, so the file is never uploaded and the tool keeps working offline. The same operation is available programmatically at POST /v1/dev/barcode-scan.

Barcode Scanner questions

Does Barcode Scanner upload my file?

No. Barcode Scanner runs as WebAssembly inside this browser tab: the file is read from your disk by the page, processed on your own machine, and handed straight back. It is never sent anywhere, so there is nothing for us to store or delete.

What files can I use with Barcode Scanner?

Any image file your browser can read. The limit is 50 MB per file.

Can I run Barcode Scanner on several files at once?

Yes. Barcode Scanner 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 Barcode Scanner?

No. Barcode Scanner 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 Barcode Scanner from my own code?

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