Free Online QR Code GeneratorPick a payload type, type your content, and the QR code updates live. Ten payload types, adjustable error correction, colors, transparent background and quiet zone — then download PNG or SVG.

Free Online Barcode GeneratorPick a format, type your data, and the barcode renders instantly. EAN-13 / EAN-8 / UPC-A check digits are computed automatically; invalid data is flagged instead of rendered as a wrong barcode.

Batch QR Code GeneratorPaste your values one per line (up to 300), choose code size and spacing, and the tool lays out print-ready A4 pages automatically. Print directly or export the whole sheet as a high-res PNG.

Free Online Label MakerChoose a label size, fill in title and text lines, optionally attach a Code 128 or QR code, and print at true millimeter scale. Two modes: repeat the same content, or one label per line.

Free Business Card MakerFill in your name, title and contact details and watch the card render live. A vCard QR code is built in — scan it with any phone camera and the contact is saved straight to the address book.

Free Online QR Code ScannerThree ways to decode QR codes: upload images (click or drag), paste a screenshot with Ctrl+V, or scan live from your camera. Results are auto-classified (URL, phone, Wi-Fi, vCard…) with one-click copy. All decoding happens locally — images are never uploaded.

QR Code BeautifierFree online QR code beautifier: custom colors, two-color gradients, square/rounded/circle dot styles, center logo, error correction L/M/Q/H and border control, with a built-in scan test. 100% in your browser, no sign-up.

Why use CodeBox?

Completely free, no hidden limits

No registration, credits, subscription walls or “N uses per day” caps. Every tool is free for everyone, with unlimited generations.

Privacy first: nothing leaves your browser

Unlike server-backed online tools, all CodeBox generation and decoding happens in your own browser. What you type (URLs, phone numbers, Wi-Fi passwords, contact details) is never sent to or stored on any server.

Instant preview

There is no submit–wait–refresh loop. The preview updates on every keystroke.

Works on any device

Fully responsive design for phones, tablets and desktops; the scanner can even use your camera live.

Who is this for?

E-commerce & shops: product QR codes and barcodes, printed in bulk for packaging.

Offices: meeting-room calendar codes, company Wi-Fi codes, QR business cards.

Warehousing & manufacturing: batch QR sheets, shelf and asset labels in standard sizes.

Individuals: home Wi-Fi QR codes, personal contact codes, and decoding codes others share with you.

FAQ

Is CodeBox really free?

Yes. All seven tools are free with no usage limits, no registration and no subscription walls.

Do I need an account?

No. Open any tool page and start working immediately.

Is my data uploaded anywhere?

No. QR generation, barcode rendering and QR scanning all happen locally in your browser. Nothing you type is ever sent to a server.

Does it work on mobile?

Can I use generated codes commercially?

Yes. Files you generate are entirely yours. One note: retail product barcodes require a GS1-registered manufacturer prefix, regardless of which tool creates the code.
