Barcode Generator

Barcode Generator Online Free

Create a barcode in seconds, right in your browser. Type your value, choose a format, and download a clean PNG image. The generator supports Code 128, EAN-13, EAN-8, UPC-A, Code 39, ITF-14, Codabar and Pharmacode, so it covers most product, shipping, inventory and library uses. Your data is processed on your device and is not uploaded to a server.

How to create a barcode

Enter the value you want to encode, such as a product number or SKU.
Select the barcode format that matches your use.
Set the bar width and height. Wider and taller bars scan more reliably.
Choose whether to show the text under the bars.
Click Generate barcode, then Download PNG.

Free Barcode Generator Without Signup

There is no account, email address or login. Open the tool, generate your barcode and download it. Nothing is stored, and you can use it as often as you like. This makes it a quick option when you only need a barcode for a label, a price tag, a spreadsheet or a one-off project.

Free Online Barcode Generator Without Watermark

The image you download is clean: no watermark, no logo and no branding added over the bars. The PNG has a white background and a quiet margin around the code, which scanners need in order to read it correctly. You can place it directly on labels, documents and packaging.

Barcode Generator With Text Underneath Free

Turn on Show text under bars to print the human-readable number below the barcode. This is useful when staff may need to type the number manually if a scan fails, and it is standard on retail codes such as EAN-13 and UPC-A. Turn the option off if you want the bars only, for example when the label already shows the number elsewhere.

Bulk Barcode Generator Online Free (Excel Lists)

This tool creates one barcode at a time. It does not import an Excel file or generate a whole column in one step. If you have a list of codes in a spreadsheet, you can copy each value into the tool and download its image, which works well for a small number of items. For hundreds of rows, a barcode font installed in Excel or a script is usually the faster route. Code 39 is the easiest format for this, because it works with a font when the value is wrapped in asterisks.

Batch Barcode Generator Online Free

For small batches, generate the barcodes one after another and give each downloaded file a clear name, such as the product code. Keep the same format, bar width and height for every code in the set so your labels look consistent and scan the same way. If you regularly print large batches, test one printed sample first before you print the whole run.

Compress SVG Image File Online Free (Vector Optimizer)

This generator exports PNG images, not SVG. If you later convert your barcodes to SVG in a design program, run the SVG file through an SVG optimizer before you publish it. Optimizing removes unnecessary metadata and shortens the path data, which makes the file smaller without changing how it looks. Smaller vector files load faster on websites and are easier to email. Always open the optimized file and test-scan the barcode once to confirm nothing changed.

Which barcode format should I use?

Code 128: accepts letters and numbers. Best for shipping, inventory and internal tracking.
EAN-13 and UPC-A: retail products. Enter 12 digits for EAN-13 or 11 for UPC-A, and the check digit is added for you.
EAN-8: small packages that cannot fit a full EAN-13.
Code 39: simple industrial and ID labels.
ITF-14: cartons and cases, with 13 or 14 digits.
Codabar and Pharmacode: libraries, blood banks and pharmaceutical packaging.

Tips for barcodes that scan well

Print at a size large enough for your scanner. Very small barcodes are the main cause of failed scans.
Use dark bars on a light background, and keep the white margin around the code.
Do not stretch or squash the image after you download it.
Test-scan a printed copy before you print a full batch.

Frequently asked questions

Is the barcode generator really free? Yes. There is no cost, no limit and no signup.

Is my data private? Yes. The barcode is created in your browser, and your values are not sent to a server.

Can I use the barcodes for retail products? The image is valid for the format you select. Retail EAN and UPC numbers must be assigned to your company by GS1 or an authorized reseller, so use your own registered numbers when selling in stores.

Why does my EAN-13 or UPC code show an error? Those formats need exact digit counts (12 or 13 digits for EAN-13, and 11 or 12 for UPC-A) and only numbers. Check for letters or spaces.

Which file format do I get? A PNG image with a white background, ready for print or digital documents.
