What is Bitmap Image File?
BMP (or Bitmap) is a classic raster graphics image file format. Originally developed by Microsoft, it stores pixel data in a raw, uncompressed format. BMP preserves maximum image quality but results in very large file sizes compared to modern compressed formats.
What is Microsoft Icon File?
ICO is a specialized image container file format used for Microsoft Windows icons and web browser favicons. It can contain one or more small images of multiple sizes and color depths, allowing icons to scale cleanly in browser tabs and operating system menus.
Why Convert BMP to ICO?
Converting BMP to ICO is standard for creating favicons and application icons. This tool writes one square image up to 256 pixels inside the ICO container, preserving the source proportions.
Frequently Asked Questions (FAQ)
Is this BMP to ICO converter safe?
Conversion runs locally in your browser. Your images are not uploaded to our server for processing.
Can I convert multiple BMP files at once?
Yes, you can drop dozens of images into the upload container. The files will be processed in batch and packaged in an uncompressed ZIP archive.
Are there any file size limits?
Processing uses your device memory. Large files or batches can exceed browser limits; try fewer or smaller images if a conversion fails.
Will my images lose quality during conversion?
PNG avoids additional lossy compression, but resizing or flattening animation can still change the result. If you choose a lossy format (such as JPEG or WebP), the output file size is reduced through mild loss of pixel details, which you can manage using the quality slider.
