BMP is an uncompressed (or minimally compressed) raster image format native to Windows, resulting in large file sizes but no quality loss.
ICO is the Windows icon format, commonly used for application icons and website favicons, and can bundle several resolutions inside a single file.
Frequently asked questions
help
Is it free?
Yes — converting files on TransConvert is free, with no sign-up required.
help
Does converting reduce quality?
It depends on the formats involved — some conversions keep everything exactly, others may show a small trade-off if the target format itself is lossy. We never add any extra compression beyond what the format requires.
help
Is my file kept afterwards?
No — files are processed to produce your download and are not kept afterwards.
help
What's the largest file I can convert?
