About ICON (.icon)
ICO (icon resource) and CUR (cursor resource) bundle multiple embedded images at different pixel sizes so the shell can pick one for a given DPI and context. Entries are directory records pointing to image blobs; on modern Windows these blobs are often zlib-compressed full bitmap payloads (embedded lossless raster blobs), while older entries used DIB-style packed pixels.
A single ICO is therefore a mini archive of rasters, not one monolithic grid. CUR adds a hotspot (x,y) for pointer alignment—metadata that matters for cursor art. When only one size is needed for downstream use, tools typically select one entry (often the largest) and decode it as an ordinary raster.
How to use
- From this hub, open “Any supported format” for the full picker, or pick a page such as “PNG image converter” for a focused SEO entry.
- On any child page, upload an image, choose the target format, then download the converted file.
- Watch transparency support because formats like JPG do not preserve alpha channels.
- Verify metadata, color profile, and visual output in your target app or browser.
FAQ
What is image converter used for?

Introduction
The Image Converter hub lists a universal converter plus one landing page per supported input extension (for example PNG or WebP). Each child page uses the same in-browser engine; format-specific intros are generated in TypeScript and prepended to this shared article.
What is image converter?
Image converter changes an image from one codec container to another, such as PNG to JPG or WebP.
Each format has trade-offs in transparency, compression, and compatibility.
Conversion should be chosen based on target environment, not only file size.
