Online QR code generators have been all the rage lately as many businesses and individuals have started using these two dimensional bar codes to exchange information. But did you know that there are also online one dimensional bar code generators?

The Bar Code News has gathered several online generators in one place on its website. You'll find a QR code generator, a 1D barcode generator that produces a sheet of bar code labels, and a barcode generator that creates a standard 1D code in one of eight different formats.

Here are some tips to help you get comfortable using these barcode generators and some ways to put the codes to work for you once you're finished.

Online barcode generator (labels)

The first online barcode generator creates a sheet of barcode labels based on your specifications. Enter your email address at the top of the page and once you complete the form, you'll receive an email with an attached PDF file. The labels can then be printed on a laser printer.

This barcode generator gives you the option of the following encoding possibilities:

(1) Code 39
(2) Code 128
(3) UPC A

Select the bar code type in the first drop down box, then enter the numbers for your specific bar code. The barcode generator supports multiple label formats (sizes) from label-maker Avery. You can create a page of labels with the same bar code or choose to increment sequential bar codes. Add a line of text across the top of the page as a reference or add your company logo. And you can create up to five pages of bar codes, as needed.

Online bar code generator (standard)

This barcode generator supports eight different standards, as follows:

(1) Code 39
(2) Code 128
(3) EAN 13
(4) EAN 8
(5) UPC A
(6) UPC 2
(7) UPC 5
(8) US Postal

As you probably know, UPC and EAN bar codes are fixed length codes that include only numbers. Code 39 and Code 128 can handle both numbers and letters. When using this barcode generator, start by selecting your bar code standard. Then choose the type of output file (either PNG or JPEG). The bar code size is defined in pixels and defaults to 40. There are five different font sizes ranging from small to large, or you can opt not to have the number printed underneath the bar code by selecting "No." There are three choices of module width, which effectively scales up the size of the bar code from left to right. Enter your data in the empty field and click on the "Generate" button.

Play around with the different size parameters in the barcode generator to get the optimal size bar code for your needs. You can save the finished image by right clicking your mouse or using Control click if you have a Mac.

Online QR barcode generator

QR codes are some of the most versatile bar codes you can find. They are capable of holding much more data than the standard 1D bar code and can add a cool look to your business card or advertisement. The QR barcode generator on the website can encode the following information:

(1) Phone number
(2) Full contact information
(3) Email address
(4) SMS (a text message)
(5) Text
(6) Website URL
(7) Information needed to access a WiFi network

The first step is to click on the drop down arrow next to "Contents," and select the information that will be included in your QR code. Then enter your data in the boxes below. For example, by choosing contact information, you'll have the ability to enter seven pieces of information (name, company name, phone number, email address, physical address, website, and a short memo such as a tagline). The last option determines the size of the QR code. Small translates into a square about 5/8" on both sides, medium gives you a 1-1/8" box, and large, a box almost 2" by 2". Then click on the "Generate barcode" button.

The QR code appears on your screen just below the online generator. You can scan it right from the screen or save the file by right-clicking your mouse (Control click if you have a Mac). The resulting file is in PNG format (portable network graphics), which can be used on a website or on print materials.
