With upscaling off, both axes clamp to the source resolution, a small icon is never magnified. SVG sources rasterize at each target size straight from the vector, not at one frozen intrinsic resolution. The ICO packs 16/32/48 PNG frames with verified directory offsets; cancel stops between encodes, before the next frame starts.Generate icon setClearPaste, drop, or type to begin. Everything stays on this device.
