Barcode Generator does one job on Android: type a number, get a scannable barcode. That is exactly the kind of task that does not need an app install, and it definitely does not need one of the ad-heavy barcode sites that make you wait through a countdown before showing the image. So we built Barcode Maker, a generator that runs right here on this page. Every barcode is computed on your device, and nothing you type is sent anywhere.

How to use it
Pick a format first. EAN-13 / UPC-A is the default and covers retail product codes: type 11 to 13 digits and the tool computes a valid check digit for you automatically, so you never have to work out the math by hand. Code 128 covers everything else: letters, numbers, and standard punctuation, useful for inventory tags, shipping labels, and internal reference codes.
The barcode updates live as you type, with the digits printed underneath exactly the way a real label prints them. The Bar scale slider controls how large the bars are, both on screen and in the file you download. Your last format, content, and scale are kept in your browser’s local storage, so the tool remembers what you were working on if you close the tab and come back. Nothing leaves your browser at any point, which also means the generator keeps working with no connection once the page has loaded.
How it compares to Barcode Generator
Barcode Maker does one thing: it turns text or a number into a standard, scannable barcode in Code 128 or EAN-13/UPC-A. We wrote both encoders from scratch, including the checksum math, and verified the output against known reference barcodes before shipping. That covers the jobs most people show up with, like labeling a box, tagging inventory, or generating a product code to test a point-of-sale scanner.
The full Barcode Generator app is built for doing this often. It supports a wider set of formats beyond the two we cover here, keeps a history of everything you have generated, and works as a standalone app you can open without a browser tab. It is also the better choice if you need to generate barcodes in bulk or want your history to persist across sessions on your phone.
Our advice is simple. Use Barcode Maker when you need one barcode right now and would rather not install anything or hand your data to a random website. Install Barcode Generator when you make barcodes often enough that a dedicated app and saved history are worth the space on your phone.
If you also need QR codes, our free QR code generator runs on the same page pattern: type, watch it redraw, download the PNG, nothing uploaded.

Barcode Generator is free on Android. It covers a broader set of barcode formats than the web version and keeps a saved history of what you have made.
Frequently asked questions
What barcode formats does this generator support?
Two: Code 128, which handles letters, numbers, and standard punctuation for labels and internal codes, and EAN-13/UPC-A, which handles the numeric product codes used at retail. If you type 11 digits we treat it as a UPC-A number and pad it to EAN-13 form; 12 or 13 digits are read as EAN-13 data, with the check digit always recalculated so the code you download is valid. Both encoders were checked against known reference barcodes before this tool shipped.
Does this barcode generator work offline?
Yes. Once this page has loaded, the generator needs no connection at all: typing, previewing, and downloading the PNG all happen on your device. Your last format and content are stored in local browser storage, not on a server.
Is it safe to use online barcode generators?
It depends on where the generation happens. Many barcode sites send your text to their server to build the image, meaning the site operator can see and sometimes log every code you generate. Barcode Maker computes the barcode entirely on your device with code that runs in your browser, so there is nothing to intercept and nothing to log. If you use another generator, check whether it states that codes are generated locally.
Is this the official Barcode Generator app?
No. Barcode Maker is an original tool we built for this page, inspired by the job Barcode Generator does. It is not affiliated with, endorsed by, or connected to the developers of Barcode Generator in any way. If you want a wider range of formats and saved history, get the official app from the store above.
Is it free?
Yes, completely. No signup, no watermark, no limit on how many barcodes you generate.
