Encoders & QR
Encode and decode URLs and Base64, then generate QR codes as PNG or SVG. No server required.
Use URL encoding for query values and path segments, Base64 when a text-safe representation is required, and QR output when the same value needs to move to a phone, label, document, or test device.
Encoding text and producing reliable QR codes
URL encoding escapes characters that have special meaning inside a URL. Base64 changes binary or text data into a portable character set, but it does not encrypt or protect the value. Decode and review output before moving it into an application or configuration file.
For QR codes, use the smallest payload that meets the task and choose enough error correction for the print or display environment. Test the exported PNG or SVG with more than one scanner before publishing it. Inputs and generated assets remain in your browser.
