Frequently Asked Questions
Is QR Code Scanner free to use?+
You can open QR Code Scanner, upload a file, and preview it for free a few times per day. Exporting/downloading the result requires DCPixel PRO — an advanced-tools upgrade that also raises the batch-processing limit (2 → 500 files) and removes the 480px resolution cap on AI-powered tools.
Does QR Code Scanner upload my files to any server?+
Never. Every operation runs locally in your browser using the HTML5 Canvas API and WebAssembly. Your files never leave your device.

Check the upload area for the full list of accepted formats. Most tools support JPG, PNG, and WebP at minimum.
