High-Quality Interpolation & Smoothing

Rescaling pixel dimensions without proper interpolation can produce jagged edges (aliasing) or blurry artifacts. EcrioX leverages advanced HTML5 Canvas rendering with imageSmoothingQuality = 'high', applying smooth bilinear and bicubic sampling algorithms to preserve fine lines, sharp text, and natural skin tones.

Format Selection & Transparency Support

  • PNG (.png): Recommended for logos, icons, and illustrations where transparent backgrounds must be maintained.
  • WebP (.webp): Next-generation image format offering up to 30% smaller file sizes than JPEG with identical visual fidelity.
  • JPEG (.jpg): Best for standard photographs, gallery pictures, and social media uploads. Transparent PNG pixels are filled with a clean white backdrop.

Frequently Asked Questions

Leave the "Lock Aspect" button active (default). When you enter a new width, the tool automatically calculates and updates the proportional height, ensuring your image never appears stretched or squished.
Pixel resizing allows you to match exact display dimensions (e.g. 1920x1080 for web banners or 1080x1080 for Instagram). Percentage scaling downscales or upscales the entire image relative to its original size (e.g., 50% reduces both width and height by half).
Yes. If you select "PNG" or "Keep Original Format", all alpha channels and transparency layers are preserved.
No. All resampling and rendering is performed locally on your device's graphics engine via browser Canvas APIs. Your images are never transmitted over the internet or saved remotely.
