Free barcode generator online — Code 128, Code 39, EAN-13, UPC and ISBN, one at a time or in barcode generator bulk from a list, downloaded as PNG or SVG.
Your privacy is protected! No data is transmitted or stored.
Type your value and the barcode is already there — there is no Generate button to hunt for. That is the whole of it: this barcode generator free online has no account, no watermark and no export fee. It is a barcode generator quick and easy enough to use once and never think about again, and the PNG or SVG drops straight into a page, which is all a barcode generator for website use really has to do.
The drawing happens in this page, so nothing you type is sent anywhere. For product codes and order references that is worth more than it sounds, because a barcode generator website that renders on its own server has seen your numbers before it hands the picture back.
| Format | Takes | Use it for |
|---|---|---|
| Code 128 | Letters, digits, symbols | Anything internal. The default, and the one most people mean. |
| Code 39 | A–Z, 0–9, a few symbols | Older scanners and systems that ask for it by name. |
| Code 93 | Same as Code 39 | When Code 39 is too wide for the label. |
| EAN-13 | 12 digits | A retail product sold in shops outside the US. |
| UPC-A | 11 digits | A retail product sold in the United States. |
| EAN-8 | 7 digits | Small packs where EAN-13 will not fit. |
| ITF-14 | 13 digits | Cartons and cases. This is the same thing as a GTIN-14. |
Code 128 is the safe answer when nobody has told you otherwise, and the barcode generator 128 free and barcode generator online 128 searches are mostly people arriving at exactly that conclusion. A barcode generator online ean 13 run is the same box with EAN-13 chosen. Use a retail format only when the number came from GS1, though, because an EAN-13 you invented yourself is a number that belongs to somebody else's product. ITF-14 is where a barcode generator gtin or barcode generator gtin 14 ends up, since GTIN-14 is the outer-carton number rather than a different symbol.
EAN and UPC numbers end in a check digit worked out from the digits before it, so a scanner can tell when it has misread one. You do not have to calculate it. Give EAN-13 twelve digits and the thirteenth is added — that is the barcode generator 12 digit and barcode generator 13 digit case in one. Give all thirteen and it is checked instead, and a barcode generator check digit that does not match is named plainly: the page says which digit it should have been rather than drawing a barcode that scans to the wrong product.
Tick Treat the input as an ISBN and the same care applies to books. A 13-digit ISBN already is an EAN-13 and is used unchanged. A 10-digit one is converted properly — the 978 prefix added and a fresh EAN check digit calculated, because the old modulo-11 digit does not survive the change. That is what a barcode generator for isbn, barcode generator isbn or barcode generator for books actually needs, and getting it wrong is how a book ends up scanning as nothing at all.
One barcode is easy anywhere. A hundred is the part that usually costs money, which is why barcode generator bulk and barcode generator online bulk are searched so heavily. Paste a list and every row becomes its own barcode; one bad row is flagged on its own and the rest still come out, so a single typo does not cost you the batch. The same applies to a barcode generator 128 bulk run of hundreds, to a barcode generator bulk 128 job written the other way round, and to a bulk barcode generator 39 batch in Code 39. Paste a barcode generator list of any length and every line is its own code, which is what a barcode generator for inventory or barcode generator for retail products count usually comes down to.
Sequence mode writes the list for you: a prefix, a starting number, how many you want, and zero padding so every code is the same width. That covers a barcode generator 128 sequence and the usual barcode generator for id card batch without typing a thousand lines by hand. Then Print sheet: pick A4 or 4 × 6 and the codes are laid out with a cutting line round each, which is what a barcode generator label, barcode generator online labels, barcode generator sheet or barcode generator for products run is really after. The page tells you how many fitted, so you know whether one sheet covers the batch.
Both are one click. barcode generator png is the one to paste into a document; barcode generator svg is a vector, which is what a printer or a design tool wants, and it stays crisp at any size — the reason barcode generator vector is worth asking for rather than scaling up a picture. The Scale setting makes a larger PNG when a barcode generator high resolution file is needed, and barcode generator transparent output is a checkbox, so a barcode generator transparent background image drops onto a coloured label without a white box round it. Whichever you pick, the barcode generator image is drawn at full size rather than upscaled from the preview.
Everything works the same on a phone. A barcode generator mobile session gets the identical formats and the identical downloads, because there is no separate app and nothing to install.
It does not make QR codes. Those are a different shape of thing and they live in the QR Code Generator, which is where a barcode generator qr or barcode generator qr code search should go. PDF417, Data Matrix and GS1 DataBar are not here either. GS1-128 is, because a barcode generator gs1 request nearly always means Code 128 with the data written in GS1's bracketed style — the symbol is ordinary Code 128, and this page draws it. The brackets themselves are yours to type.
It also does not read or scan barcodes, and it does not plug into Excel or Word. It draws them and hands you a file. What you do with the barcode generator code after that — a label, a sheet, a product page — is outside what a barcode generator tool can sensibly promise.
