Barcodes Online Service

dLSoft's Barcodes Online Service provides a subscription service which enables you to generate barcode images on your smartphone, tablet or computer for most common 1D or 2D barcodes (types supported). Subscribers may create the image using the online barcode generator and have it instantly e-mailed to them in any of the following formats: BMP, GIF, JPG, PNG, or TIF bitmap formats or EPS or WMF vector formats.   Images may be created for resolutions at up to 1200 dpi.

The generator will remember your barcode settings for when you return, so in most cases you would need only to change the barcode data to create subsequent barcode images.

If you need advice on the recommended size for a particular barcode type please see our recommended Barcode Sizes page. If you need advice on obtaining numbers for barcodes or graphics information  please see below or visit our "Where can I get a barcode" page.

If you are not a subscriber the service will generate barcode images but will not e-mail them to you or remember your barocde settings.

Service Details

dLSoft's Barcodes Online Server provides a simple cost-effective way of obtaining barcode images on demand. The images may be e-mailed to you within seconds of you providing the details.

dLSoft's Barcodes Online Server presents the user with a form for specifying barcode details. You can see the form by accessing the server even without a password - but you will not be able to e-mail the barcode image if you do not have a valid subscription. Once you have e-mailed a barcode image the server will remember the barcode settings, and these will be used the next time you logon to the service - or until you change the settings yourself.

If you are concerned about the settings you should use we would be pleased to set up your first barcode for you, just e-mail your requirement before requesting a subscription to give us time to enter the settings.

The service allows you to create barcode images at a specified resolution and to e-mail the image in any of BMP, EPS, GIF, JPG, PNG, TIFF or WMF formats. These are the same images as those produced by our Really Simple Barcodes and AnyLabels products and our dBarcode.NET developer components.

Potential subscribers may request a trial image to by e-mail.  We DO NOT refund subscriptions for any reason.

The e-mail address provided when you subscribe is the one you use login to the service, and the one to which barcode images are sent. The service also allows you to enter a second e-mail address to receive copies of the barcode images, and this may be changed at any time. While placing the e-mail message in the mail queue takes only a second or two, receipt of the message by the your e-mail system may take longer - depending on where it is located, the mail system used by your ISP and the state of the internet.

Note that at the end of a subscription period or when the barcode image limit is reached the subscription is closed. If you wish to renew please request renewal by e-mail or resubscribe from this page. Subscriptions are NOT automatically renewed.

Frequently Asked Questions

Retail Barcode numbers

For use on retail products you cannot just invent the numbers. You must register with your national article numbering body (GS1UK in the UK, the GS1US in the USA) to obtain a company code number and a range of product code numbers. Together these numbers form Global Trade Item Numbers (GTIN) which form the data for the barcodes. Without these numbers your barcodes will not be recognised when you products are scanned at a retail outlet. Furthermore you will probably need to use either EAN (in Europe), JAN (in Japan) or UPC (in the USA) barcode types for retail products, and, if appropriate, you may need to use Code 128 or EAN 128 barcodes on boxes containing multiple items.
For contact points in the UK see GS1UK or for most other countries see GS1

Graphics information

Generally TIFF images are fine for most computer systems (including Macs), although we can provide BMP, EPS, GIF, JPEG, PNG or WMF if you prefer. A resolution of 600 dpi is suitable for retail and "normal" size barcodes, although we can provide 300, 400, 600, 1200 or 2400 if required. EPS is a vector format suitable for use on most computer systems. The WMF format is a vector format, but only suitable for use on Windows PCs. If you have a graphics designer who will use the images the designer will be able to tell you which format and resolution is preferred.

If you are creating barcodes for use in a retail environment (eg. GS1/EAN-13 or UPC-A) then you should also consider the size of the barcode. The recommended barcode sizes page provide the sizes you would use for creating the barcode at 100% of the nominal size recommended by GS1. GS1 typically permits the size the range between 80 - 200% of this nominal size, and that means when both the height and the width of the image vary by the same proportion. If you need to truncate the barcode to fit on small packaging you are advised to check that the resellers of your products find this acceptable (in our experience many will, but some won't!)

The following extract from the GS1 specifications explains the reason for this:

“Truncation of a barcode symbol is the reduction of the barcode symbol height relative to the width. Truncation is not recommended because it destroys the ability of a symbol to be scanned omni-directionally at the point of sale. A truncated symbol can only be scanned when the trade item is oriented in particular directions across the scanning beam. Truncation therefore reduces checkout efficiency. The more the height is reduce the more critical becomes the alignment of the symbol across the scanning beam. Truncation should be avoided unless absolutely necessary, for example, when printing on a highly curved surface, and then the maximum height should be printed.”
