ICO Converter

ICO converter provides a server-side capability to generate ICO icon files from common image assets. It accepts PNG, JPEG, BMP, WEBP, and SVG inputs; SVG is rasterized to bitmaps during export. The tool produces standard icon sizes such as 16x16, 32x32, 48x48, 64x64, and 256x256 by default, with optional additional sizes. Transparency is preserved where the source contains an alpha channel, ensuring crisp edges across sizes. Outputs can be delivered as a single ICO or as a ZIP containing multiple icons for batch use.

Conceptually, the workflow analyzes each input, resizes it to every requested size using high-quality resampling, and packs the results into ICO containers. It supports 32-bit color depth with alpha, enabling proper transparency in all sizes. When an SVG is provided, the vector is rasterized at the target resolution before resizing. The process is deterministic and designed for automation in build pipelines, sprite sheets, and icon libraries.

Who benefits include frontend engineers, UI designers, and agencies needing consistent icon sets across platforms. The tool's value lies in reducing manual editing, enabling batch processing, and ensuring reliable delivery of compatible icons for apps, websites, and desktop software. It is suitable for bootstrapping icon suites, accelerating asset pipelines, and standardizing iconography across projects.
