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.

Can I download as PNG, JPG, SVG, or PDF?

Yes. Generators export PNG and high-quality JPG for photos and forms, SVG for design tools, a tight PDF of the code alone, and a print PDF centered on A4 or Letter.

Are my QR codes uploaded to a server?

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