QR Code Generator
Make a QR code for a link, text, WiFi or contact.
Never uploadedValidated as you type, with any required check digit computed for you.
Keep the white space either side when printing, and never scale width and height independently - both are the usual reasons a barcode stops scanning.
CODE128 for general use, EAN-13 or UPC-A for retail products.
The format is validated live and any check digit is computed for you.
Use SVG for print so the bars stay crisp at any size.
CODE128 for internal use and anything alphanumeric - it is the flexible default. EAN-13 and UPC-A for retail products, but those need a real registered prefix. CODE39 for older industrial scanners.
A final digit computed from the others so a scanner can detect a misread. EAN-13 and UPC-A require one, and it is calculated for you as you type.
You can generate a scannable image, but a barcode you made up is not registered to you and must never go on a product for sale. Retail barcode prefixes come from GS1.
Usually it is printed too small, has too little white space around it, or is stretched. Keep the quiet zone either side, do not scale the width and height independently, and print at high contrast.
Generate barcodes in every common symbology - CODE128, EAN-13, UPC-A, CODE39, ITF and more - with the value validated as you type and any required check digit computed automatically. Pick CODE128 when you just need something scannable for internal tracking, since it handles letters and numbers. EAN-13 and UPC-A are for retail products and need a prefix registered with GS1: a number you invent will produce a scannable image but must never go on something you sell.
