Image Upscaler

While no digital upscaling can create new detail, our advanced algorithms (especially Lanczos) do an excellent job of enlarging images while preserving the existing quality and reducing artifacts. The result depends heavily on the original image quality.

For best results, start with high-quality source images. Low-quality images will still show some quality limitations after enlargement.

We support JPEG, PNG, WebP, and GIF formats for input. You can output in JPEG, PNG, or WebP formats depending on your needs.

Yes, to ensure optimal performance and prevent browser crashes with extremely large images. Since all processing happens in your browser, we've set generous limits:

• Maximum file size: 50MB
• Maximum dimensions: 8192x8192 pixels
• Processing is done efficiently in your browser for optimal performance

Absolutely! All image processing happens directly in your browser using JavaScript. Your images are never uploaded to our servers or any third-party services.

For most images, Lanczos provides the best quality. Bilinear is faster but may produce softer results. Nearest Neighbor is fastest but best for pixel art or diagrams where you want to maintain the blocky appearance.

We recommend trying different algorithms on your specific image type to see which gives the best results for your use case.

Image enlarger and image upscaler are essentially the same thing - both terms refer to increasing the resolution and size of an image. 'Upscaler' is a more modern, technical term commonly used in digital imaging, while 'enlarger' is the traditional term. Our tool works as both - it upscales your images using advanced interpolation algorithms to increase resolution while maintaining quality.

Yes! Our image upscaler is perfect for preparing images for high-resolution printing. You can enlarge small images to meet print quality requirements (typically 300 DPI).

For best print results, start with the highest quality source image possible and use the Lanczos algorithm for maximum quality preservation.

Processing time depends on the image size and your device's performance. Small images (under 1MB) typically process in under a second, while larger images (10-50MB) may take a few seconds to a minute.

Since all processing happens in your browser, the speed depends on your computer's processing power. The tool will show a 'Processing...' status while working.

If your image exceeds our limits (50MB file size or 8192x8192 pixels), you'll see an error message. You'll need to resize or compress your image first before using our upscaler.

• Maximum file size: 50MB
• Maximum dimensions: 8192x8192 pixels
• Try compressing your image first if it's too large

Yes! Our image upscaler is completely free to use for both personal and commercial purposes. There are no restrictions on how you use the enlarged images.

Our image upscaler works in all modern browsers that support HTML5 Canvas and File API:

• Google Chrome (recommended)
• Mozilla Firefox
• Microsoft Edge
• Safari (macOS and iOS)
• Opera

For best performance, we recommend using the latest version of Chrome or Firefox.
