Are my ICO files uploaded?

No. The ICO to BMP conversion runs entirely in your browser, so your images never leave your device.

Will the image quality change?

PNG, BMP and ICO are lossless, so every pixel is preserved. JPG and WebP use compression you can tune with the quality control when it is available.

Can I convert many images at once?

Yes. Add as many as you like and download them together as a single zip.

About this conversion

ICO is the Windows icon format used for favicons; BMP is an uncompressed bitmap with no quality loss. Converting ICO to BMP re-encodes each image in your browser: the pixels are decoded and written back out in the new format, and nothing is uploaded.
