No sign-up." canonical: https://reroutehq.com/tools/barcode-generator --- # Free Barcode Generator UPC-A, EAN-13, EAN-8 and ITF-14, rendered in your browser and downloadable at print resolution. No account, no watermark. A retail barcode encodes one number and nothing else. That number — a GTIN — is what a checkout looks up, so the barcode has to be the right symbology for where the product is sold, and it has to carry a valid check digit. This generator handles both, and renders the result as vector SVG so it stays sharp at any print size. UPC-A is the twelve-digit format used at retail in North America. EAN-13 is its thirteen-digit international equivalent, and EAN-8 is the compressed version for packaging too small to carry a full symbol. ITF-14 encodes the shipping-container number on outer cases rather than on consumer units, which is why it is usually printed with bearer bars — the heavy rule around the symbol that stops a scanner misreading a partial scan on corrugated board. Everything renders on your device with JsBarcode. The number you type is never sent to us, which is also why there is no limit on how many you make. ## How to use it 1. **Pick the symbology** — UPC-A for North American retail, EAN-13 internationally, EAN-8 for small packaging, ITF-14 for shipping cases. 2. **Enter the digits** — Type the number without spaces. The generator tells you immediately if the length or check digit is wrong, rather than producing a symbol that will not scan. 3. **Set the appearance** — Toggle the human-readable digits, change the bar and background colours, and turn on bearer bars for ITF-14 cases. 4. **Download for print** — SVG for artwork, PNG for a quick placement, PDF for handing to a printer. Vector output means no resolution to get wrong. ## What this will not do - This renders a barcode from a number you already have. It does not issue GTINs — those are licensed from GS1, and printing a number you do not own will not scan correctly at a retailer. - A barcode is static by nature: the number is the bars. If you need something you can repoint after printing, that is a dynamic QR code, not a barcode. - ITF-14 is generated using ITF encoding. Confirm the check digit against your own GS1 records before committing a case print run. ## Frequently asked questions ### Is this barcode generator really free? Yes, and it needs no account. Barcodes are rendered in your browser, so they cost us nothing to produce and there is no limit, no watermark and no expiry. The number you type never reaches our servers. ### Which barcode format do I need? UPC-A for products sold at retail in North America, EAN-13 for most of the rest of the world, EAN-8 where the packaging is too small for a full symbol, and ITF-14 on shipping cartons rather than consumer units. ### Can I get a barcode number here? No. GTINs are licensed from GS1 and we do not issue them. This tool turns a number you already hold into a scannable symbol. Using an unlicensed number will fail at a retailer even if the barcode itself scans. ### What size should I print it? Download the SVG and let your printer scale it. Vector output has no fixed resolution, so it stays crisp at any size. Avoid scaling a PNG up — that is where unscannable barcodes come from. ### What are bearer bars? The heavy rule printed around an ITF-14 symbol. On corrugated board a scanner can clip the edge of a symbol and read a partial number; the bearer bar makes that misread fail instead of returning the wrong value. ### Do you support GS1 Digital Link? Yes, but that is a different thing. A Digital Link is a QR code carrying a GTIN in a web address that a resolver answers. Retail point of sale is being asked to read 2D barcodes by the end of 2027, so most packaging will carry both for a while.
