Yes, you can customize both the QR code foreground color and the background color using the color picker options. ### What is the difference between PNG and SVG formats? PNG is a standard image format suitable for most digital uses, while SVG is a vector format that remains sharp at any size, making it ideal for printing. ### What does the Error Correction Level mean? It determines how much of the QR code can be damaged or obscured while still remaining scannable. Higher levels are better for codes that might be partially covered or printed on uneven surfaces. ### Is there a limit to the amount of text I can encode? While you can encode large amounts of text, keep in mind that more data increases the complexity of the QR code, which may make it harder to scan. ### Are these QR codes free to use for commercial purposes? Yes, all QR codes generated with this tool are free to use for both personal and commercial projects. ## Related tools - [Barcode Batch Generator](https://elysiatools.com/en/tools/barcode-batch-generator): Batch generate Code 128, EAN-13, UPC-A, ITF-14, QR Code, and Data Matrix outputs from CSV or multiline text - [QR Code Decoder](https://elysiatools.com/en/tools/qr-code-decoder): Decode QR codes from images and extract the contained text or URLs - [Barcode Generator](https://elysiatools.com/en/tools/barcode-generator): Generate CODE128 barcode from text with fixed dimensions - [Fitness Workout PDF Generator](https://elysiatools.com/en/tools/fitness-workout-pdf-generator): Generate a printable workout-plan PDF from JSON or CSV data with exercise tables, progress boxes, and optional QR video links - [PDF QR Barcode Labels](https://elysiatools.com/en/tools/pdf-qr-barcode-labels): Batch generate printable labels with QR code and barcode in a single PDF - [Slug Generator](https://elysiatools.com/en/tools/slug-generator): Generate clean URL slugs from any text, with built-in Chinese-to-Pinyin conversion.
