Open tool -
QR Code Generator
Generate URL, text, Wi-Fi, email, phone, SMS, and vCard QR codes with logo, transparent background, gradients, Hex colors, error correction, and multiple downloads.
Open tool -
QR Code Decoder
Decode QR codes from images, screenshots, clipboard, camera, or screen capture. Batch-process many files, decode multiple QRs in a single image, parse Wi-Fi, vCard, email, SMS, geo, and calendar payloads, and export .vcf, .ics, annotated PNG, or bulk JSON / CSV.
Open tool -
Barcode Generator
Generate 1D and 2D barcodes such as Code128, Code39, EAN, UPC, ITF-14, PDF417, and Data Matrix with validation hints, a live preview, and PNG, SVG, or JPG export.
Open tool -
Barcode Decoder
Decode Code 128, Code 39, EAN, UPC, ITF, Codabar, PDF417, Data Matrix, Aztec, and other barcode images with upload, paste, camera scanning, inversion and upscaling retries, plus JSON and CSV export.

About this category
Encoding turns arbitrary bytes into characters that survive transports — URLs, JSON fields, email bodies, terminal logs. Decoding goes the other way, usually during debugging when a value comes back as gibberish that started life as a token, an image, or a query string.
This category covers the everyday encode and decode round-trips you reach for during API work, plus visual encoding into QR and barcode images you can print, paste, or scan from a screen.
What you can do here
-
Base64 with text and file modes
Round-trip text, binary, or image data with explicit UTF-8 handling and a clear distinction between standard and URL-safe variants.
-
URL and HTML encode and decode
Encode whole URLs, single query values, path segments, and HTML entities — then decode back, including UTF-8 percent sequences and common named entities.
-
QR codes for links and short payloads
Generate PNG/SVG QR codes with sizing, error-correction, and margin options for posters, slides, table tents, and product labels.
-
Barcodes for logistics and retail
Generate Code 128, EAN, and UPC barcodes with the correct check digit and bar widths for label printers and shop-floor scanners.
