A Blog QR code stores the payload directly in the graphic, so scanning it triggers the action immediately with no redirect in the middle. That makes it reliable, free to create, and immune to a link service going away.
This tool prepares the exact payload format for blog, so you do not need to learn the underlying specification. Fill in the fields and the correct string is generated for you.',
Keep the encoded content as short as possible. Every extra character increases the density of the modules, and a denser code is harder to scan from a distance. Shorten the destination link if you can before you encode it.
Maintain contrast and leave the quiet zone alone. Dark modules on a light background scan most reliably; the quiet zone around the code must stay clear for the scanner to find the edges. If you add a logo, raise the error-correction level to compensate for the covered area.
Do not shrink the code below roughly 2 cm per 10 characters of content. Do not place the code on a busy background or a curved surface without testing, and always scan the finished graphic on two different phones before you send it to print.
Yes. Blog is completely free — no account, no watermark and no limits. Generate as many QR codes as you need and download them instantly.
Open the tool, enter the required details, optionally customise colours and add a logo, then download the code as PNG or SVG. The whole process takes under a minute.
No. Every QR code generated with QRCodegener is static and permanent, so it keeps working for as long as the destination link or content stays valid. You can download a print-ready copy in up to 2K resolution.
Yes. Upload a logo to place it in the centre, then raise the error-correction level so the code remains scannable under the logo.
Keep at least 2 cm across for short content measured at expected scanning distance. If the destination is a long URL, increase the size proportionally.
