Will resizing reduce the visual quality of my image?

Downscaling preserves sharp visual detail using smooth bicubic canvas sampling. Upscaling beyond original dimensions may show softness.

What does "Lock Aspect Ratio" mean?

Locking aspect ratio ensures width and height scale proportionally, preventing your subject from appearing stretched or squished.

Can I resize transparent PNG and WebP images?

Yes. Transparent backgrounds are fully preserved when exporting to PNG or WebP formats.

Are my images uploaded to MixtureTool servers?

No. All image decoding, scaling, and canvas rendering happen strictly on your device inside your web browser.

What is the recommended size for web images?

Standard full-width hero images should typically be 1600–1920px wide, blog content images 800–1200px wide, and avatars 100–200px wide.
