Free Barcode Generator

Yes. There is no sign-up, trial or watermark. Make as many barcodes as you need and download them as PNG, SVG, PDF or EPS, or copy the image.

For products sold in stores, EAN-13, or UPC-A in the US and Canada. For books, ISBN. For outer cartons, ITF-14. For your own labels, such as inventory, shipping or asset tags, Code 128, which holds letters and digits in a compact barcode. Code 39 and Codabar are mainly for older systems that already use them.

You can draw it here, but the number has to be yours. GS1 assigns product numbers to companies, so a made-up number may already belong to someone else's product. Get your numbers from GS1, then enter them here to make the barcode images.

The last digit of a UPC, EAN, ISBN or ITF-14 number. It is calculated from the other digits, so a scanner can tell when a digit was misread. Enter the number without it and the tool adds it, or enter the full number and the tool checks it.

Usually because of a typo in one of the digits. The tool shows which last digit the number should have. Check the number against your GS1 record or packaging, or enter it without the last digit to have the check digit calculated.

UPC-A has 12 digits and is used mainly in the US and Canada. EAN-13 has 13 digits and is used in most other countries. A UPC-A number is the same as an EAN-13 number with a leading 0, which is why scanners often report UPC-A codes with 13 digits.

Yes. Enter an ISBN-13, which starts with 978 or 979, or an ISBN-10, which is converted to its 978 ISBN-13. The barcode is an EAN-13 with the ISBN printed above it. ISBNs come from your country's ISBN agency. The 5-digit price add-on that some books carry isn't supported yet.

Shipping labels, inventory, asset tags and other internal labels. It holds letters, digits and symbols, up to about 80 characters here, and stays more compact than Code 39 for the same text.

No. Code 39 starts and ends with an asterisk, and the tool adds both automatically. They appear in the text under the bars, as they do on most Code 39 labels.

Both are 2D codes. Data Matrix fits more data into a smaller square and is common on small parts, electronics and healthcare products, where industrial scanners read it. Phone cameras usually open links from QR codes, so for anything people scan with their phone, use a QR code instead.

Numbered prefixes in brackets that say what each piece of data is: (01) is the GTIN, (17) the expiry date, (10) the batch or lot number, (21) the serial number and (00) the SSCC of a pallet. Write them one after another, such as (01)05012345670003(17)271231(10)AB12. The tool checks GTIN and SSCC check digits and dates, and lists each element by name.

As YYMMDD: 271231 is 31 December 2027. A day of 00 means the end of the month. The tool rejects dates that don't exist, such as a 13th month or 30 February.

No. The tool makes general PDF417 codes from your own text, but it doesn't create driver's license or ID card data formats.

A Code 128 barcode can hold the text of a link, but phone cameras don't open links from barcodes. For a link people can scan with their phone, use a QR code instead.

After every change, the tool decodes the exact PNG and SVG a download would produce and confirms they scan as the value you entered. PDF and EPS files are drawn from the same design. If they don't, it names the likely cause, such as low contrast or red bars.

For EAN-13 on consumer products, GS1 recommends a thinnest bar of 0.330 mm and a bar height of 22.85 mm, with clear quiet zones on both sides. Under Size and print, choose your printer and the thinnest bar in mm or mils: the tool shows the printed size, warns when an EAN-13 falls outside GS1's limits, and makes every download at that size. Test a printed proof with the scanner you'll use.

Printers draw whole dots: 203, 300 or 600 per inch. A width like 0.33 mm is 2.6 dots on a 203 dpi label printer, so some bars would print 2 dots wide and others 3. The tool rounds the thinnest bar to whole dots (3 dots, 0.375 mm, at 203 dpi) so every bar prints exactly as designed, and tells you the width it used.

Yes, but keep dark bars on a light background. Most barcode scanners read with red light, so red, orange and yellow bars can disappear even though they look dark on screen. The tool warns about low contrast, light bars and red bars.

PNG works in documents, label software and online stores; with a printer chosen, it has one pixel per printer dot and is tagged with that DPI, so it prints at the size shown. SVG, PDF and EPS are vector files made at your print size: SVG for websites and design apps, PDF for printing and sharing, EPS for print shops and older label software. PNG, SVG and PDF can have a transparent background.

Yes. Under Bulk, upload a CSV, TXT or Excel (.xlsx) list or paste one value per line, up to 1,000 at a time, or make a number sequence. Every barcode uses the type, size and colors you set, and you can download them as PNG, SVG, PDF or EPS files in a ZIP, each scan-checked and listed in a report, or as a label sheet PDF.

Yes. Choose Label sheet and a layout: letter sheets of 30 labels (1 × 2⅝ in, the size of Avery 5160), A4 sheets of 21 (63.5 × 38.1 mm, the size of Avery L7160) or 24 (70 × 37 mm), a custom grid, or one label per page for roll label printers. You can print several copies of each barcode, start at any label on a part-used sheet, and add a caption from your list. Print at 100% (actual size) and test on plain paper first.

Excel stores long numbers as numbers: it drops leading zeros, so 036000291452 becomes 36000291452, and very long ones turn into 5.01235E+12. Format the column as Text before typing or pasting the numbers. The bulk tool warns when values look like they lost a zero or were shortened.

Yes. Choose Number sequence and set a prefix, a start number, how many, a step and the number of digits, such as BOX-0001 to BOX-0100. For UPC and EAN, the check digit is added to each number. Only use product numbers from your own GS1 range.

No. Barcodes are created and checked in your browser. The barcode engine loads from this site the first time you make a barcode, and the numbers and text you enter are not sent anywhere.
