Frequently Asked Questions
What is BMP format?
BMP (Bitmap) is an uncompressed image format that stores every pixel individually. Files are large but compatible with virtually all software, especially legacy Windows applications.
When should I use BMP?
BMP is best when you need an uncompressed format for specific software requirements, legacy compatibility, or as an intermediate format for further processing. For most uses, PNG is a better choice.
Why are BMP files so large?
BMP stores raw pixel data without compression. A 12MP iPhone photo could produce a 36MB BMP file vs ~5MB PNG or ~2MB JPG. Only use BMP when specifically required.
Are my files private?
Yes. All conversion happens in your browser. No files leave your device.
