How to Use QR Code Generator

1
Open the tool
Navigate to QR Code Generator on ImageSize — no signup or install required. The tool loads instantly in your browser and works on desktop, tablet, and mobile devices with a modern browser.
2
Upload your file
Drag and drop your image or document into the dashed upload area, or click to browse. Accepted formats are shown below the dropzone. Files are read locally and never sent to any server.
3
Adjust settings
Use the sliders, dropdowns, and buttons in the tool panel to configure output. A live preview updates as you change options so you can see results before exporting.
4
Process
Click the main action button to run processing. ImageSize uses your device's CPU for conversion, compression, or editing. Progress and success toasts confirm when your file is ready.
5
Download
Save the result to your device with one click. Original files are never modified. You can run the tool again with different settings without re-uploading to any cloud service.

Is this tool really free?: Yes. ImageSize is free with no daily limits, watermarks, or paywalls on tool functionality. We believe privacy-respecting utilities should be accessible to everyone, from students to professionals.
Do you store my images?: No. Processing happens in your browser's memory. When you close the tab, that data is gone. We do not operate an upload endpoint for your media files.
Why use browser-based tools?: Browser tools are faster for many tasks because there is no upload queue. They are more private because your photos never travel across the internet. They also work offline once the page is loaded.
Are there file size limits?: Most tools accept files up to 50MB. Larger files may work but depend on your device's available RAM. For very large RAW or TIFF files, consider exporting a smaller copy first.
Can I use results commercially?: You retain all rights to your images. ImageSize does not claim ownership of your output. Ensure you have the right to edit any source material, especially stock photos or client work under contract.
What browsers are supported?: Chrome, Firefox, Safari, and Edge in recent versions work best. Enable JavaScript and avoid private modes that block local storage if you want theme preferences to persist.
