High-Fidelity Browser Rescaling
Daliy.Tools utilizes hardware-accelerated HTML5 Canvas bicubic interpolation to recalculate pixel values. This preserves sharp edges and vibrant colors while reducing file weight.
Since processing happens directly in your browser's memory, your photos are never uploaded to remote cloud servers.
Frequently Asked Questions
Will resizing my image reduce its quality?
Downscaling preserves high visual quality while reducing file size. When upscaling, our interpolation engine smooths pixels to minimize blur.
Can I lock aspect ratio to avoid distortion?
Yes. Aspect ratio lock is enabled by default so your image proportions remain perfectly natural.
What image formats are supported?
We support JPG, JPEG, PNG, WebP, GIF, SVG, and BMP images.
Can I resize images for Instagram or web banners?
Yes. You can enter any standard dimensions like 1080x1080 for Instagram square or 1920x1080 for Full HD.
