Are barcodes uploaded to a server?

No. Mewix draws and reads barcodes in your browser. Nothing is uploaded.

QR code vs barcode — when to use which?

Use a 1D barcode for retail SKUs and scanners that expect EAN/UPC/Code128. Use a QR code for URLs, WiFi, contacts, and phone camera scanning.

No. Generation and scanning run entirely in your browser on Mewix. Files and payloads never leave your device.

Ensure the bars are sharp, well lit, and not skewed. Crop to the barcode and avoid heavy compression artifacts.

Yes. Built-in Camera apps on modern iPhone and Android devices read standard QR codes, including WiFi, URL, and contact payloads.

Read EAN, UPC, Code 128, and other barcodes from a photo or camera. Decoding stays on your device — nothing is uploaded.

Scan a barcode or QR code

Drop a PNG or JPG, or use your camera. Decoding stays on this device.

Upload or use camera. Drop a clear photo of the barcode or start the device camera.
Read the value. Mewix decodes the symbology and shows the text plus format name.
Copy the result. Copy the barcode value for inventory, search, or spreadsheets.

Common 1D formats such as EAN-13, UPC-A, Code 128, Code 39, and related types, plus QR when present in the image.
